What is file conversion. Topic: converting files to various formats

One of the most popular formats electronic documents are DOC and PDF. Let's see how you can convert a DOC file to PDF format.

You can convert DOC to PDF either using software that works with the DOC format or using special converter programs.

Method 1: Document Converter

First, we will study the method using converters, and we will begin our consideration with a description of the actions in the AVS Document Converter program.

1. Launch Document Converter. Click on "Add Files" in the center of the application shell.

   

   If you like to use the menu, then in this case, click "File" And "Add Files". You can apply Ctrl+O.



2. The shell for opening the object is launched. Move in it to where the DOC is located. With it selected, press "Open".

   

   You can also use another algorithm of actions to add an element. Move to "Explorer" to the directory where it is located and drag the DOC into the converter shell.



3. The selected item is displayed in the Document Converter wrapper. In a group "Output Format" click on name PDF. To choose where the converted material will go, click on the button "Overview…".



4. A shell appears "Browse folders...". In it, mark the directory where the converted material will be saved. Then press OK.



5. After displaying the path to the selected directory in the field "Output Folder" you can start the conversion process. Click "Start!".



6. The DOC to PDF conversion process is in progress.



7. After its completion, a miniature window appears, informing you that the operation was completed successfully. It also prompts you to go to the directory in which the converted object was saved. To do this, press "Open. folder".



8. will be launched "Conductor" in the place where the converted document is placed with PDF extension. Now you can perform various manipulations with the named object (move, edit, copy, read, etc.).

The only disadvantage of this method is that the Document Converter is not free.

Method 2: PDF Converter

Another converter that can convert DOC to PDF is Icecream PDF Converter.

1. Activate Icecream PDF Converter. Click on the caption "To PDF".



2. A window opens in a tab "To PDF". Click on the inscription "Add File".

If there are several objects, then simply circle them with the cursor holding the left mouse button ( paintwork). If the objects are not nearby, then click on each of them paintwork with key pressed ctrl. Free version application allows you to process no more than five objects at the same time. Paid version theoretically has no restrictions on this criterion.

   

   Instead of the two steps above, you can drag a DOC object from "Explorer" into the PDF Converter shell.



4. The selected objects will be added to the list of converted files in the PDF Converter shell. If you want the output to be a single PDF file after processing all the selected DOC documents, then check the box next to "Combine everything into a single PDF file". If, on the contrary, you want a separate PDF to correspond to each DOC document, then you do not need to check the box, and if it is, then you need to uncheck it.

   By default, converted materials are saved in special folder programs. If you want to set the save directory yourself, then click on the icon in the form of a directory to the right of the field "Save to".



5. Shell starts "Select Folder". Move in it to the directory where the directory where you want to send the converted material is located. Select it and click "Select Folder".



6. After the path to the selected directory is displayed in the field "Save to", we can assume that all necessary settings transformations are done. Click the button to start the conversion. "The envelope.".



7. The conversion process starts.



8. After it is completed, a message will appear informing you of the success of the task. By clicking on the button in this miniature window "Open Folder", you can go to the location directory of the converted material.



9. IN "Explorer" the directory where the converted PDF file is located will be opened.

Method 3: DocuFreezer

The next way to convert DOC to PDF involves using the DocuFreezer converter.

1. Start DocuFreezer. First you need to add an object in DOC format. To do this, press "Add Files".



2. The directory tree opens. Using the navigation tools, find and mark the directory on the left side of the program shell that contains the desired object with DOC extension. The contents of that folder will open in the main pane. Mark the desired object and click OK.

   

   There is another method for adding a file to process it. Open the DOC location directory in "Explorer" and drag the object to the DocuFreezer wrapper.



3. The selected document will then be displayed in the DocuFreezer list. In field "Destination" select an option from the dropdown list PDF. In field "Save to" the path to save the converted material is displayed. The default is a folder "The documents" your his user profile. To change the save path if necessary, click the ellipsis button to the right of the specified field.



4. A tree-like list of directories opens, in which you must find and mark the folder where you want to send the converted material after conversion. Click OK.



5. This will then return you to the main DocuFreezer window. In field "Save to" the path that was set in the previous window will be displayed. Now you can start converting. Highlight the name of the file to be converted in the DocuFreezer box and press Start.



6. The conversion process is in progress. After its completion, a window opens, which says that the document was successfully converted. It can be found at the address that was previously registered in the field "Save to". To clear the list of tasks in the DocuFreezer shell, check the box next to "Remove successfully converted items from the list" and press OK.

Flaw this method is that the DocuFreezer application is not Russified. But at the same time, unlike previous programs, which we reviewed, it is absolutely free for personal use.

Method 4: Foxit PhantomPDF

The DOC document can be converted to the format we need using Foxit PhantomPDF PDF viewer and editor.

Method 5: Microsoft Word

You can also convert DOC to PDF using the built-in toolkit of the program Microsoft office or third-party add-ons in this program.

1. Launch Word. First of all, we need to open DOC document, which we will later transform. To go to the opening of the document, move to the tab "File".



2. In the new window, click on the name "Open".

   

   You can also directly in the tab "Home" apply combination Ctrl+O.

3. The shell of the object opening tool is launched. Move to the directory where the DOC is located, select it and press "Open".



4. The document is open in the Microsoft Word shell. Now we have to directly convert the content open file in PDF. To do this, click on the section name again. "File".



5. Next, move on the inscription "Save as".



6. The object save shell is launched. Move to where you want to send the created object to PDF format. In the region of "File type" select an item from the list PDF. In the region of "File name" You can optionally change the name of the created object.

   Here, by switching the radio button, you can select the level of optimization: "Standard"(default) or "Minimum Size". In the first case, the quality of the file will be higher, since it will be intended not only for posting on the Internet, but also for printing, although, at the same time, its size will be larger. In the second case, the file will take up less space, but its quality will be lower. Objects of this type are primarily intended for placement on the Internet and reading content from the screen, and this option is not recommended for printing. If you wish to contribute additional settings, although in most cases this is not required, then click on the button "Parameters…".



7. The options window opens. Here you can set the conditions for whether you want to convert all pages of the document to PDF or only some of them, compatibility settings, encryption, and some other parameters. After desired settings entered, press OK.



8. Returns to the save window. All that's left is to press the button "Save".



9. After that, a PDF document based on the contents of the original DOC file, will be created. It will be located in the location specified by the user himself.

Method 6: Using add-ins in Microsoft Word

In addition, you can convert DOC to PDF in the Word program using add-ons third party manufacturers. In particular, when installing the above-described Foxit programs PhantomPDF, add-in is automatically added to Word FoxitPDF, for which a separate tab is allocated.

We found out that you can convert DOC to PDF using both converter programs and using the internal functionality of the Microsoft Word application. In addition, there are special add-ons in Word that allow you to specify the conversion parameters more accurately. So the choice of tools for performing the operation described in this article is quite large for users.

Many of computer users I'm sure you've come across this problem more than once. Often during work, it becomes necessary to select some piece of text, report or other fragment for further work.

To work you need:

In conclusion, it must be said that the transformation of documents is nothing supernatural. Of course, at a certain stage of working with each program, difficulties may arise, but it will not be difficult to solve them.

For achievement best result most the best option will use at least once each service described above and determine for himself which one is most convenient for you to work with.

Among the many possibilities provided web services 2.0 has the ability to convert files. Data conversion is the conversion of data from one format to another. Usually with the preservation of the main logical-structural content of information.

Data conversion can occur both during operations with files (file-to-file operations) and on the fly (for example, when importing and exporting data).

The conversion can be lossy or non-lossy. Usually associated with the "richness" of a particular data format. For example: conversion from "plain text" format to "OpenDocument Text" format will almost always be lossless, since the OpenDocument format includes everything and even more possibilities than the plain text format. But the conversion from the OpenDocument Text format to a plain text format will most likely preserve the entire text component, but almost always (except for the most simple cases) will result in loss of text formatting (bold/italics, fonts, tables, page placement, and other data will be lost).

Applications designed to convert files can be divided according to the type of files that convert:

Video files;

Text;

and by application type:

Provided by Internet resources;

Installed on PC.

An application for an example of considering the technology of working with converters is located at http://www.zamzar.com.

This online application supports over 1200 different format transitions, includes:

Audio converter;

Video converter;

Music converter;

Image converter;

Converter e-books;

CAD Converter is a multi-purpose converter.

Figure 5

Interface this application English, but quite simple.

To convert a file, select the “Convert Files” tab, where in the first window you will need to select the file to be converted on your PC, in the second window select which format you want to convert the selected file to, in the third window indicate your mail address, where after the conversion it will be sent link to download the converted file, in the fourth window there is a button, when clicked, the conversion process starts. You can convert files no larger than 100 megabytes, which in relation to e-books, images and music does not bring anything bad because it is unlikely that an e-book, music, and even more so an image can have a size of under 100 megabytes (according to at least, as for e-books, often this size is definitely not found).

The algorithm for working with the application is as follows:

1. In the first window, select the file on your own PC, which we are going to convert, and upload it.

2. In the second window, select the format to which you want to convert the downloaded file.

3. In the third window, specify the address Email, where, after the file is converted, a link will be sent where you can download it.

4. In the fourth window, the "Convert" button starts the file conversion.

After starting the file conversion, the conversion progress can be tracked by filling the progress bar.

After the conversion process is completed, a link to the file is sent to the specified email address, where you can download it. When converting, it must be taken into account that during conversion, as mentioned earlier, part of the data may be lost due to the "poor" format into which the file will be converted. The conversion process itself does not take much time, in the case of large files, it takes ten minutes, even with slow data transfer, which, however, does not affect the conversion process at all, since the file has already been uploaded to the application website. I will also mention that given internet the resource is free, but there are features provided and for a fee, to which you can subscribe. To check the speed of this resource, I converted the file "ELTECH - Construction of power supply systems for LED systems - 2010" from pdf format to doc format in less than a minute and a half, the file had a size of 2.32 megabytes. After downloading from the link that was sent to the specified email address and found that there was no loss of data during the conversion, at least visible, which indicates a high-quality file conversion performed by this online application.

Today, there is often such a thing as converting or converting files from one format to another. As it became known, not all users understand what it is, and also on what principles this process is carried out.

Thus, it is worth considering this issue in more detail. For this, we will take as an example universal format PDF, which today is one of the most common, designed for documents of various types.

Fundamentals of the concept: what does conversion mean?

If you deviate from technical parameters, it can be noted that the conversion is a translation from one format to another. In other words, this is the usual conversion of one file. Of course, most users are misled by the very concept of "format translation". Many people, due to their own inexperience, are of the opinion that file conversion is carried out simply as a result of renaming, changing only the extension to another one. This is fundamentally wrong.

In addition, this renaming has nothing to do with conversion. Moreover, the resulting file cannot be opened not only in the program associated with this extension, but also in the "native" application. First of all, it is necessary to understand exactly that this is a process in which the logical-structural content of the data is partially or completely preserved. It should be noted that there are two types of conversion:

Converting from file to file;
changing the format on the fly.

As for the second type of conversion, it is often found in data export or import operations.

Programs for converting To correctly convert the structure of any document or file, special programs are used, which are called converters. They are also divided into types:

narrowly focused;
universal.

As you can immediately understand, in the first case, these programs are focused specifically on several of these formats. The second type of converters consists of big list very different data that does not belong to the same class of data types. True, this versatility often calls into question the quality of the file obtained after conversion. In this article we will talk about the PDF format, as it is considered the most versatile for office documents that can contain text part, graphics, as well as other structures from the field of multimedia.

Convert to PDF text files

Most simple processes are text to PDF conversions. Ordinary text files, which are created using Notepad, should not be considered. It is necessary to take the most common DOC format, corresponding to the Microsoft Word application. IN this case The conversion process will take place in several ways. The first is to use a normal save. When the "Save as ..." command is selected, a window pops up on the screen, where the type of data to be saved is at the bottom.

You just need to click on the drop-down list and select the field indicating the type of PDF document in it. It is denoted in parentheses by the .pdf extension. It is worth noting that given function exists exclusively in office packages released in 2010 and beyond. If they were produced earlier, the conversion to PDF document Word provides for the use of additional plug-ins that are built into the Word shell.

One such plugin is Save program as PDF or XPS. It is developed by Microsoft Corporation. When the installation of this utility is completed, the corresponding field will appear in the format menu during the saving process. These two options are part of a process called on-the-fly conversion. To perform direct conversion, it is suggested to use other converter programs. For instance, Solid Converter PDF or Word to PDF Converter. As for the first program, it is used more often, as it is capable of converting both forward and backward. In other words, this is a direct conversion to PDF of a Word document, as well as a reverse one from PDF to DOC format.

Convert PDF to word document

As already mentioned, the program discussed above is suitable for this process. In addition, it is possible to use converters of the PDF2Word Converter type. However, there is no significant difference in this case. PDF to Word conversion is performed using similar algorithms. As a rule, this is not particularly important, since the main thing is the result.

True, it is believed that the best conversion option is to use the utility Adobe Reader. It also contains the "Save As..." command, as well as a list of supported extensions and document types. You must select a Word document, and then the on-the-fly conversion is performed. In addition, there is an opportunity to use another simple option.

To do this, select the required fragment or entire structure in the PDF document, and then copy it to the clipboard. Next, you need to paste into the text word editor to save it for saving. However, there are also disadvantages. First of all, they are associated with a violation of the structure or formatting of the document. However, these methods are still convenient and effective.

Convert images to PDF and vice versa

It should be noted that all information perceived visually can be converted to PDF format. This also applies to graphics. For such manipulations are usually used specialized programs under names like JPEG to PDF Converter, Image to PDF Converter, and more. The processing procedure is similar to that used in the case of office documents. Any program designed for converting in the area also functions identically. inverse transformation. It should be noted that in most cases you can use your own Adobe features reader. True, in this case you will need to select a graphic file type from the format menu.

Online Services Capabilities

It is also possible to do such transformations manually. To do this, you can find many online converters on the Internet. They are easy to handle. Just upload your file to specific service, determine the conversion direction with the choice of the final format and activate the conversion procedure. In just a couple of minutes, a file will be received, which should be saved to your hard drive.

Thus, it became clear what methods are used to convert files. It is worth noting that it is better to spend a few minutes installing the required programs or find portable versions that do not provide for the installation process. This will be a better option than using online services, since the result may not be what the user expected. However, this applies more to working with graphic material that should be converted to PDF format. For text documents You can use Word and Adobe Reader.

Hello my dear readers!
Did you know that every file or document on your PC, whether it's a picture, an audio file or any video, has its own extension, that is, the file type. Each file type belongs to a corresponding category:

You can click on any category to go directly to it.

Remembering myself about 3-5 years ago, I had no idea about the number of file types that I know about now. As I mentioned in the article About the Author, I received my higher education at the STEP Academy in Kyiv. But before entering there, it was necessary to pass an interview and pass a small test exam. So, one of the tasks of the exam was to write 5 - 7 types of files related to images with a description of their occurrence and properties. You won’t believe it, but apart from jpeg, gif and png, nothing else came to mind, but even knowing these types of files, I didn’t know how they differ and how ... . Sad isn't it? And this is a man who was going to be a web designer. Well, so that you are not as far from the knowledge of elementary file types and can, if necessary, tell who needs what it is and what it is eaten with, I am writing this article.
There is just great amount types and extensions of files, and even a day is not enough to describe all of them. Therefore, I will take only the most used categories and of course the most common file types related to these categories. Let's start with the audio.

Drawings, images.

So the most common types of image files are: JPEG, TIFF, GIF, RAW, and the most common bmp file. All of these files are raster images, but there are more files and stock vector images like: ai, cdr, cmx, eps, fla. And now a few words about raster and vector.

Raster graphics- this is a graphic in which image data is stored in pixels, where each pixel has its own color value of its corresponding model (RGB, CMYK, LAB, HSB). Basically, these are the graphics that are used on digital media. It has the so-called blurring property when zoomed in - loss of quality. Vector graphics- this is graphics that has mathematical data that operate not with points, but geometric shapes, which make up the drawing itself. When we apply zoom (enlargement) to such a drawing, then such a drawing is practically redrawn anew, which does not incur any loss of quality.
Well, now let's take a short tour of the types of these types of graphics.
JPEG- stands for Joint Photographic Experts Group, that is, the name of the company that developed it. This file is compressed, and with a slight loss of quality, it is the most common graphic format for today. You can open it: any viewer or graphics editor, as well as any of the currently existing browsers.
TIFF- Tagged Image File Format, which sounds like this from English - a format for storing raster graphic images. Probably one of the most common file types used in printing houses, as well as in faxes and scanners. As well as jpeg, it is possible to open the majority of graphic editors.
gif- matters Graphics Interchange Format File, can easily store a certain sequence bitmaps, which we often refer to as nimation. This type of file is created mainly by video or graphics editing programs. The format is used in digital advertising, as well as in visual design video. You can open it with any browser, and programs for processing and editing graphics or video editing.
RAW- Raw Image Data File, which means raw in translation. This is data obtained from the matrix of high-quality cameras that does not have any processing and compression in itself, and has a lot of weight. The advantage of such a file is its subsequent processing. Opened and processed special programs or powerful editors type Adobe Photoshop, JRiver media center or rawstudio.
AI– this format applies already to vectors, program-generated Adobe Illustrator. Here it is important to take into account the factor that the file created in a more new version will not open in a later one, or it will open but with the loss of some data. This format creates high quality drawings, but unfortunately is not compatible with other formats.
cdr– This vector file type belongs to CorelDraw. Which has no less popularity than the same Illustrator. As is the case with Illustrator, the program has many versions, and each format of the new version will not be able to be opened in a later version. The very quality of saving the picture in this format is excellent, but there are pitfalls, namely, the format is poorly readable in many similar programs working with vector.
Eps- The format can be safely attributed to the number of universal ones, since programs such as Macromedia FreeHand, CorelDraw, Adobe Illustrator and many other analogues can easily work with it. This vector graphics format also has its own versions, and here you need to be careful, since not every program will be able to open newer versions of this extension.
wmf- Well, how can Microsoft do without its own experience in vector graphics. This type of vector graphics is used exclusively in Microsoft Windows. Although any other program can open it, you should not bother with it, since it does not have the quality of the picture that is present in the above examples.

Video files:

Let's move from graphics to video. I already wrote an article about, in which I mentioned video-related formats.
VHS- an outgrowth of the past, a video format that was used on video cassettes. (Pleasant memories when a whole horde of friends sat at someone’s house and enthusiastically watched a purchased action movie on a cassette), oh, there was a time, now everything is not so and there are fewer friends with whom you can sit like this near the box.
DV (Digital Video)- a format developed by world video recording studios. This is also a cassette series, but of higher quality and which was worked on by more than one leading company, such as Panasonic, Philips, Hitachi.
AVCHD- the recording format of high-definition video files and characteristics, such as 720p, 1080i and 1080p, the media in this case were Blu-ray discs as well as memory cards. We all know it as HD video or HD picture quality. This is the most modern look digital video. The format that began to be used everywhere, and there is probably no such person who would not know what DH quality is for a video.
MPEG-1– Compression format for media such as CD. Video format does not produce High Quality pictures and has an extension of 352x240, isn't it funny. It's very rare to see him in action these days. But you know what it is.
MPEG-2 This format has been widely used DVDs, it allows you to capture HDD and Flash cameras. Previously, this format was used in some DVRs, and it was also used by AXIS Communications.
MPEG-4– A video format that combines well-known codecs: DivX, XviD, H.264, etc. Due to its compression, it has a good data transfer rate. Well, it's worth mentioning that it is supported a large number of DVD players.
HD( high definition) - The most powerful video format in quality, having two types of resolutions referred to as: HD1 (1280x720) and of course HD2 (1440x1080), respectively. But to appreciate this quality, you need a widescreen display of LCD monitors or TVs.
AVI- Dear readers, this is not a format at all, as we all used to think, it is Microsoft development- a container that can easily store 4 streams, such as: video, audio, text and midi. Impressive, isn't it. I am already silent about the scale with which the whole world uses it. Now let me tell you a little secret. You probably noticed that not always AVI files are read by your device, then there is no sound, then there is no video, but there is sound. So the reason is that the AVI container may contain a codec that your reader does not have. To solve this problem, I advise you to download and install the assembly on your PC K-Lite Codec pack. Forget about your problems forever.
WMV- The result of the diligence of Microsoft, this video format is their own development, the result of the video processed in movie maker. In any build of Windows, it will open without problems, it is easy to encode it into another format with the same program that I wrote about in the Installation and configuration post Format programs factory.
MOV- We talked about Microsoft format, it's time to mention Apple, here MOV format and is the creation of this company. At its core, the format is not bad and can contain both graphics and animation, as well as 3D. But it has a drawback, it is not always played by standard players. Sometimes you have to download and install QuickTime Player.
mkv- He's obedient AVI format, can easily contain audio, video, different menus, text, etc. True, there is one significant difference between it and AVI; its code is open and available to anyone. Although it does not have the same popularity as AVI, it has good prospects.
3gp- Well, how can I not mention this format, because we are all familiar with it since our first phones, when the presence of a 20-second video on a mobile spoke of your coolness brighter than any words. You guessed it right, this is the format mobile devices. In which everything is compressed and distorted to disgrace. Today it can only be found on old wap-sites.

And now about the formats used on the Internet:

FLV– The main flash video format for posting and distributing videos on the Internet. It is used by such platforms as YouTube, Rutube, Yandex video, Google video and many others.
SWF- the result of the animation created using the program Adobe Flash. Will be played by all browsers using the installed in them Flash plugin player.
If we draw a parallel between FLY and SWF, then SWF is a flash movie, but FLV is a flash video, well, something like that.
RAM, RM, RA- This is a unique development of RealNetworks, known for the scandal for developing a program capable of licensed discs, which are protected from overwriting, copy to the user's PC. So this format is used for broadcasting on the network, which of course cannot but rejoice. With its help, we can watch IPTV.

Let's move on to the category of audio formats.

What is bitrate?! is the amount of information transmitted in a given period of time. The essence of his principle is how much information we can devote to each second of the playback of our audio file. It is generally accepted to use Kbps or Mbps as a unit of measurement, the second option is less common, you yourself understand why. Now let's move on to the formats directly.
WAV- is one of the quality formats audio that transmit sound quality without compression or loss. True, there is one drawback in this quality, such files take up a lot of memory, which is not entirely advisable on the network for sites. The quality will usually be between 192 Kbps and 320 Kbps.
WMA- the development of Microsoft in order to compete with the well-known mp3 format. What came out of this you can see for yourself. You have all the tracks in your phone WMA format? I knew it. Although partially they were able to achieve a small file size and a more normal sound quality.
FLAC is a format for everyone. This type of audio file is perceived adequately by all platforms and media without exception. It can be compared with the principle of WinRAR known to us, because this format first compresses the file, and during playback, as it were, unpacks it.
MIDI- Globally different from their counterparts. These are not just sounds, but a whole set of different commands for the sound of certain sounds. I don't have one recording studio, which would do without this format. There is just a gorgeous article on this topic, where everything is chewed into pieces, I advise music lovers to read.
MP3- Here, as they say, comments are unnecessary. The most widely used audio format, both online and offline. It is undeniable that this is the most compressed format, and in this plus it takes up very little space. But where there is compression, there is a correspondingly large loss of quality and subtlety of sound. When compressing the track, everything that is almost imperceptible to the human ear is cut out, so we practically do not see the difference between it and the same WAV.
AIFF- format for machines running on Mac OS. This type of file also works without compression, therefore it has no loss in sound quality, therefore it is used along with WAV and SDII in professional audio and video applications.

Text and document formats.

Doc– The most common format of the well-known program from Microsoft Word, which is part of the software package for Windows Microsoft office. Its disadvantage is poor compatibility with other text editors, and even among themselves they are not quite compatible in versions such as 2003, 2007 and 2010.
FB2 – Text format e-books, recently gaining broad scale and is used in many readers. One of the quality readers is Cool Reader.
PDF- A very common document. A format that can contain both text and graphic elements. Developed by adobe systems. Supports both raster and vector graphics, which is a definite plus and convenience. Most word processing programs easily export data to a pdf document.
RTF- The format is still the same adobe company, although it was originally developed by both Microsoft companies and Adobe. Text formatting is built using meta tag formatting. It can be opened and saved by WordPad, OpenOffice, TextEdit. Although there is no mass character in this format.
