Hello readers of my blog!
I think everyone knows such a program as adobe reader which is free. It facilitates opening, viewing and printing pdf documents. The browser automatically detects the adobe reader during installation and installs a plugin for it. After that, you can view all documents for this format.
You, as users, will be able to add comments, graphic notes, callouts, lines, and more. Unfortunately (and for some, fortunately), in practice there is no program that can completely protect a document from copying.
I want to note that you can protect your author's text by "not showing" it completely. On the site, you can post certain excerpts of your work, and the full text for download can only be offered after payment. But if this option does not suit you, then consider a number of protection programs.
Quite often used free PDF Freeze converts pdf to image. This way the content is protected. This program is aimed at replacing text with an image (). The content cannot be copied or highlighted, which will create difficulties during operation.
The tool in question has encryption methods that prohibit the ability to print, copy, edit. The application is available in several themes.
To convert a file to an image, you must first download and install PDF converter freeze. Next, open a simple interface, add a PDF file from your computer, select the quality level and encryption method. You simply specify the parameters you need and click on the "Freeze" button.
After that, you should open a new window in which you should specify where to save the output image.
Ready! Image PDF find where indicated. As you can see, the program is elementary and will not bring difficulties even to an inexperienced computer scientist.
Online protection
There is an online protection method. To do this, just follow the link. The tool allows you to encrypt a document completely and protect some properties of a PDF file (for example, only print or copy protection).
There are three methods you can use.
First, you only allow the document to be opened after the correct password has been entered.
Secondly, you always allow the text to be opened, but restrict certain actions. For example, prohibit its printing.
Thirdly, you can combine the above two options - set a password and simultaneously restrict actions.
Two passwords are set - “user” and “administrator”. If the recipient sets a "custom" password, they will be able to view the document. You, using the "administrator" password, have full control over the document and, if necessary, print it.
The maximum allowable size is 50MB. If you need to protect a file big size, then you will have to wait a few minutes, since uploading to the server takes some time and directly depends on the connection speed.
Thus, with the help of the methods described above, you can take measures to preserve your copyright on the PDF document.
Sincerely! Abdullin Ruslan
We all use PDF documents quite often. This is due to its functionality and convenience. However, each of us may encounter the need to remove protection from a PDF file. This may be needed for different reasons, for example, in order to print text, edit a file, open it in a non-standard way through Photoshop, convert from this format to another so that the file can be read by another device, and so on.
The reason for this is completely irrelevant. The main thing is that if the PDF file is protected, you will not be able to do all of the above. Therefore, our task today is to learn and understand how not to become a hostage of this situation. So how do you unprotect a PDF file? Below I will describe several ways that allow you to do this. However, all of them can only remove the password from these documents. You won't be able to find out exactly what it was, but after that you can do whatever you want with the file.
If you look for programs that provide removal of protection from PDF files through search engines, then the vast majority of them will be paid. But I still managed to find a few working methods that cost me nothing. It is them that I will now share with you, which will save you from the dreary search for a solution.
Online Services
Let's start with online services, thanks to which the protection of PDF files can be easily removed. Advantage this method is that you will not need to download the software to your HDD, then install the software with all the ensuing consequences. After all, I am absolutely sure that you are not so often wondering How to remove protection from a PDF file? As a rule, such a need in life arises a couple of times.
How to do it?
Using your browser, go to www.freemypdf.com. This resource is quite old, but for all its time of existence it has proven itself quite well. It not only allows you to remove the password, but also removes restrictions such as security PDF files from copying, from printing, and the like. However, if your file initially asks for a password even just to open it, then this service won't be able to help you.
So, I'm telling you how to remove protection from a PDF file using this online service. We go to the site, then click on the file selection button. Next, you need to specify the path to the file that you want to unlock. Remember that the volume of such a document should not exceed one hundred and fifty megabytes. Otherwise, this method will not be able to help you. When the file is specified, click on the button that says "Do it!" We are waiting for some time. After that, it will be possible to download the required document without a password and in decrypted form.
Second way
The second way to get rid of the password is www.pdfunlock.com. It works on the same principle as the one above. Drag and drop your document password protected, right in the window of this site. If the file was on your hard drive, click the "My Computer" button. If it is found, click on the button " Google Drive" or "Drop Box". Next, you need to click on the "Unblock" button and wait until the process of removing protection is completed.
Free software
Now it's time to learn how to unprotect a PDF file using free software. Let's start with the first program called "PDF Password Remover Tool". Download it from the developer's site. Just do not confuse this software with a similar one called "PDF Password Remover". Latest Program does everything the first one does, only it costs twenty-nine US dollars.
How to use?
How to use this miracle? And everything is very simple. Even a schoolboy can figure out the interface of this software. We find the field called "Open PDF file", and in it we indicate the document that needs to be "neutralized". Next, go to the field called "Save PDF file", where you need to specify the name under which it will be saved new document no longer protected. Find the "Convert" button and wait for the process to complete. This software is able to cope with many passwords, so, as a rule, there is no need to look for any other solutions to this problem.
We move on. I present to your attention the following program, which will allow you to unlock a protected document. It's called "Free PDF Unlocker" and you can also download it from the developer's site. It is quite simple and allows you not only to get rid of the password, but also to remove any prohibitions and restrictions on PDF files. This is both print protection and copy protection. It does not present difficulties for her and the ban on opening files. She easily overcomes this obstacle. However, it is not always able to cope with some new documents that have enhanced protection.
Paid software
All of the above is usually enough to remove the password. These methods are quite simple and do not require any material investments. But if, for some reason, none of the above methods solved your problem, and the PDF document still has a password, try using another program called "Very PDF Password Remover". You can download it, like all the previous ones, on the developer's website.
The full version of this software costs one thousand Russian rubles, but trial version it won't cost you anything. You can easily figure out its interface, and for sure it will do everything you need. The program copes with any difficulties that relate to the PDF format.
There is also a sea of similar software, usually paid, which I do not see the need to use, because, as you can see, there are enough free programs that solve the problem. If you still decide to use the paid software, then the best of options I also suggested.
I will end here, because I told you everything I wanted to. All listed ways They definitely work, because I personally checked them more than once. I hope I saved you from wasting your time looking for a solution to this actual problem on Internet resources, as well as thematic forums.
