There are situations when you need to reduce the size of the jpg file, or, simply put, compress. In this article, we will look at several ways to reduce the size of .jpg images.
There can be several reasons for reducing the jpg file:
- Takes up less disk space
- Site pages load faster on the site
- Some services impose restrictions on the maximum image size.jpg
Let's look at a specific example. Let's have the following image
The image is 477 KB in size and 1600 x 1012 pixels wide. Let's reduce it in a couple of ways.
1. Reduce the .jpg size using Paint
This is the most affordable way to compress a picture. Its most important advantage is that this graphics editor is installed on all computers as a default program that operate on the Windows operating system. To get into the Paint image editing environment, just right-click on the image and select "open with Paint" from the drop-down menu.
The window that opens contains information about the original image size, which is displayed in pixels and as a percentage. Practice shows that it is easier to change jpg in pixels. Adjust the horizontal parameters you need, and do not forget to leave a tick next to the "Maintain proportions" item, so that the height changes automatically and the picture is not distorted.
Confirm the action with the OK button and save the result.
So we have achieved the expected result:
Now our jpg image is 404KB (up from 477) and has a resolution of 1200 x 759 pixels instead of 1600 x 1012 pixels. The result is so-so. Considering that the quality after clicking the "Save" button in Paint deteriorates.
2. Reducing JPG File Size Using Paint.NET
The Paint.NET program itself is very convenient to use due to its clear Russian-language interface. In addition, it takes up very little space, it can be downloaded on the Internet for free.
In order to get into the Paint.NET image editing environment, you need to right-click on the image, and in the "Open with" drop-down list, select the Paint.NET program.
In order to change the image of the jpg file, in the "Image" menu, select the "Resize" item, which is located at the top of the window.
After these steps, a window will open in which you will need to configure the file resolution.
Attention! Do not forget to leave a check mark next to the "Maintain aspect ratio" option so that the image is not distorted.
This time we have reduced the file size by a factor of two. We confirm the changes with the OK button, save the image.
Now the size of the jpg file is only 83 KB, not 477, has an extension of 600 x 380 pixels, while not losing image quality (reduced by 83%). Is this still not enough? 83 KB out of 477 is not the limit.
This image is only 18KB in size and has an extension of 260 by 160 pixels. This compression option is perfect for forums that do not support the ability to install heavy avatars.
The methods we have considered above are good, similar actions can be done in Adobe Photoshop or PhotoFilter, but the result will be the same.
But what if you don't want to download some programs to your computer, but do everything online? Services that allow you to edit images decently, there are plenty to even choose from.
3. How to reduce jpg file size online on the Internet
This option is perfect if you don't have any graphic editors at hand, and you need to reduce the size of the photo right now. There are a lot of such editors on the Internet now. You can reduce the jpg file using the compressjpeg.com online service.
The site greets us with a simple user interface. Before us is the "Download" button. We load the image we need.
This graphical editor has such an easy and intuitive user interface. Using the slider to the right of the image, you can adjust the compression quality of our image (the more the image is compressed, the more it loses its quality).
1. Quality - 100%. Image without any changes. File size - 478KB.
2. Quality - 50%. The image is no longer so clear, but it has not undergone any radical changes. The size of the new file is 155 KB.
3. Quality - 10%. The image is of terrible quality, the pixels are so large that the image is as if "glued" from squares. The size of this picture is 33 KB.
We select the compression method we need, then confirm the changes with the "SAVE" button, and download the finished file with the corresponding button at the top.
Summing up, I would like to say that the best program for reducing the size of a jpg file is the Paint.NET program, since it provides the largest list of settings for image compression, and besides this useful function, it also has a lot of other useful tools.
There are times when you need to quickly reduce the amount of space on your computer's hard drive, which is taken up by a photo in JPG format. It is desirable that the procedure takes place without significant loss of picture quality. There are several easy ways to make photography "lose weight."
Is it possible to reduce JPG size online
The weight of the picture is taken as its size in megabytes, which sometimes needs to be made smaller. This procedure is extremely necessary for those who often work with photographs, because modern devices take pictures of considerable size. It will not be possible to store a significant number of "heavy" drawings - this requires an additional hard disk, and often the price for one more information storage is high. However, special programs have already been created that reduce the volume of pictures. In addition, before installing them, you can try compressing photos online.
On the World Wide Web, you can find many services with which you can figure out how to compress a JPG photo to a smaller number of megabytes. They all work according to the same principle - the user uploads the necessary image to the site, clicks just one button, and after a while the system will ask to save the image with a reduced size to the computer. Internet services are completely free, so this method of compressing photos without losing quality is considered one of the best and fastest.
As a standard, such portals have many additional functions and capabilities - cropping a picture, turning in the right direction, mirroring, or even adding beautiful frames / effects. The resources are freely available, so to find them, you just need to enter a query into any search engine, and in a second get a whole list of photo compression sites.
How to compress a JPG file
It also happens that the speed of the Internet or the technical data of the computer / browser does not allow uploading photos to the network. Then special services come to the rescue that can compress photos without losing quality. You can use third-party utilities or standard (basic Windows set). Therefore, before you can reduce the JPG file, you need to figure out how these programs do their job.
How to compress a photo to the right size in Paint
Paint is a standard Windows program for processing any images, so there is no need to install it. With its help, you can easily compress photos to the desired format. You do not need to download it, it is already present in the basic set of the operating system. The program is easy to use - a few mouse clicks are enough to make the picture of the desired size. How to reduce the size of a JPG file using Paint:

How to reduce the weight of a JPG file in Photoshop
A very popular service that will help you figure out how to reduce the size of a JPG file without degrading quality is Photoshop. A graphic editor with a wide range of functions can frighten inexperienced users with an abundance of incomprehensible buttons. However, if you know the sequence of actions, then it will be easy to reduce the number of megabytes in photos. Before compressing a JPG using Photoshop, you need to install it. What to do after that:
- Open the picture with Photoshop (right-click on the photo, "open with", select Adobe Photoshop).
- Alternatively, the picture can be opened directly from the utility - the "File" tab - the "Open" item.
- In the upper work area of the "Image" menu, then select "Image Size".
- The window that opens will allow you to select all the necessary proportions of the photo (centimeters / pixels, width).
- At the bottom of the window, be sure to check the box "Maintain proportions" (when changing parameters, they will be edited evenly).
- In the "File" menu, select the "Save As" sub-item.
- Choose a jeepg format that will keep the original quality.
- After choosing the format, click on the "Save" button.
Other Ways to Compress JPG without Losing Quality
To process a picture and reduce its weight, you can use third-party utilities, online web services - some of which are free, but you will have to pay to work with others. They provide different percentages of image compression, which is important - without affecting the quality. If you don't know how to reduce the size of a JPG file, then in the table below you can find the programs you need to help in this simple task:
| Utility / web service | Platform | Compression, percent |
| JPEGmini Lite |
However, even the most successful frames do not pass the tests on your favorite sites: the size or weight of the image exceeds the maximum limit. And users are storming the search engine trying to figure out how to reduce the size of a jpg file.
But how can you reduce the size of the jpg file and not end up with a photo with clearly visible pixels? First, you need to understand what the weight and size of an image is.
Image resolution and size
Users who are not constantly working with graphic editors often confuse such basic concepts as resolution and image size. Trying to figure out how to reduce the size of a jpg file, many people change the resolution and vice versa.
The size of a photograph or image is the physical manifestation of the picture, that is, the size in centimeters, millimeters, inches, etc.
Image resolution is a well-defined number of pixels per inch. Measured linearly - the number of points in one straight line.
Data on image resolution are provided by manufacturers of cameras and photographic equipment: from 320x240 to 7680x4800. The higher the resolution of the camera, the clearer and better the photo or video clip will be.
It is worth noting that when the physical data of the image - the size - changes, the number of pixels will remain constant, but they will be stretched over a larger space. Thus, the clarity of the picture will be lost. By reducing the size of the photo, but not changing the resolution, you can take a picture of better quality.
How do I reduce the size of my JPG file?
However, how can you modify the file without resorting to programs? One of the easiest answers to the question of how to reduce the size of kb of a * .jpg file is to get help from the resources involved in changing the image online. But keep in mind that these types of sites usually host an incredible amount of ads. Almost every click leads to a third-party resource.
When choosing a site that will help you resize a photo, you should be careful. To get started, search resources where users share reviews about various things, and choose those that have been awarded the most stars or "pluses".
However, due to the fact that the resizing work is done automatically, the quality of photos can be noticeably affected.
Photoshop: a quick way to resize an image
One of the most popular graphic editors - Photoshop - is most often used by ordinary users to apply filters and resize photos and images. Many do not even have questions about how to reduce the size of a jpg file in Photoshop.
To reduce the physical parameters of the file, you must first open it in a graphical editor. Then open the "Image" menu and select the "Image size" item. You can also use the Alt + Ctrl + I keyboard shortcut to open the dialog box.
To change the physical parameters of the picture, you need to change the width and height of the photo. The icon combining the metrics allows you to keep the aspect ratio of the base file. These indicators are usually measured in centimeters or pixels, but there are also percentages, inches, millimeters, points and peaks.
The next step is to save the changes. This can be done by selecting the "Save As" item in the "File" menu or using the hot keys Ctrl + S. Further, the graphics editor will offer to select parameters: format and quality, or otherwise, the weight of the image.
Resizing a picture in Paint
Owners of personal computers on which a graphics editor is not installed can use the help of the program preinstalled in the Windows operating system - Paint.
The question of how to reduce the size of a jpg file in Paint is simple to answer. First of all, you need to open the file in the program. Then select the item "Resize and Skew" in the drop-down menu or use the keyboard shortcut Ctrl + W.
The window that appears will offer to change or tilt the image. Physical parameters can be changed: horizontally or vertically. To achieve the best quality, it is recommended to check the "Maintain proportions" option.
And the last step is to save the resulting image.
Change resolution in Photoshop
On many sites where you need to add an image to your profile, there is a limitation not only on the file size, but also on its resolution. For example, the weight of an avatar should not exceed 100-150 kilobytes. In such cases, changing the physical parameters of the photo is unlikely to help.
In order to change the weight or resolution of a photo in Photoshop, you need to open the file in a graphics editor and click on the "Image" menu. Next, find the item "Image size".
Below the already known parameters that determine the width and height is the line "Resolution". This parameter is measured in pixels per inch, or pixels per centimeter.
Change photo weight in Paint
Unfortunately, the built-in Windows Paint program did not include such a function as "reduce the weight of the * .jpg file while maintaining the size". This editor only allows you to change the size of the photo and its tilt.
However, if the original file has a file extension other than JPG, you can still find a loophole and resize the image. The fact is that formats such as BMP, RAW and others are very heavy.
To change the size, it is enough to open such an image in the editor and select the "Save As" item in the menu and change the format to JPG. In most cases, the weight of the photo will immediately decrease several times.
Hello. Quite often, when working with graphic files (pictures, photographs, and indeed any images) they need to be compressed. Most often, this is necessary to transfer them over the network or put them on the site.
And despite the fact that today there are no problems with the volumes of hard drives (if it is not enough, you can buy an external HDD for 1-2 TB and this will be enough for a very large number of high-quality photos), store images in a quality that you will not need - not justified!
In this article, I want to consider several ways how you can compress and reduce the size of a picture. In my example, I will use the first 3 photos that I come across on the vastness of the worldwide network.
1) bmp is the image format that provides the best quality. But you have to pay for the quality with the space occupied by the pictures saved in this format. The size of the photos they will occupy can be seen in screenshot # 1.
Screenshot 1. 3 pictures in bmp format. Pay attention to the size of the files.
2) jpg is the most popular image and photo format. Provides reasonably good quality with amazing compression quality. By the way, please note that a picture with a resolution of 4912 × 2760 in bmp format is 38.79MB, and in jpg format it is only 1.07MB. Those. the picture in this case was compressed about 38 times!
As for the quality: if the picture is not enlarged, then by eye it is impossible to recognize where is bmp, and where is jpg. But when you enlarge a picture in jpg, blur starts to appear - this is the effect of compression ...
Screenshot # 2. 3 pictures in jpg
3) png - (portable network graphics) is a very convenient format for transferring pictures on the Internet (* - in some cases, pictures compressed in this format take up space even less than jpg, and their quality is higher!). Provides better color reproduction and does not distort the picture. Recommended for images that should not lose quality and that you want to upload to a website. By the way, the format supports transparent background.
Screenshot # 3. 3 pictures in png
4) gif is a very popular format for pictures with animation (more about animation :). The format is also very popular for transferring pictures on the Internet. In some cases, it provides the size of pictures smaller in size than in the jpg format.
Screenshot No. 4. 3 pictures in gif
Despite the huge variety of graphic file formats (and there are more than fifty of them), these files (listed above) are most often found on the Internet, and indeed in general.
How to reduce image size in Adobe Photoshop
In general, of course, for the sake of simple compression (conversion from one format to another), installing Adobe Photoshop is probably not justified. But this program is quite popular and those who work with pictures not even so often have it on their PC.
1. Open the picture in the program (either through the "File / open ..." menu, or the combination of buttons "Ctrl + O").
3. Set the save settings:
Quality: depending on the selected quality (and you can set the compression from 10 to 100), the size of the picture will depend. Examples of compressed images with different quality will be shown in the center of the screen.
After that, just save the picture - its size will be an order of magnitude smaller (especially if it was in bmp)!
Result:
The compressed image began to weigh less, about 15 times: from 4.63 MB was compressed to 338.45 KB.
Other image compression programs
1. Fastone image viewer
One of the fastest and most convenient programs for viewing pictures, easy editing, and, of course, compressing them. By the way, it allows you to view pictures even in ZIP archives (many users often install the AcdSee program for this).
In addition, Fastone allows you to reduce the size of tens and hundreds of images at once!
1. Open the folder with the pictures, then select the ones you want to compress with the mouse, and then click on the "Service / Batch Processing" menu.
Move the pictures from the left to the right (those that we want to compress);
Choose the format we want to compress them into;
Actually that's all - after that, just press the start button. By the way, in addition to this, you can set various settings for image processing, for example: crop edges, change the resolution, put a logo, etc.
3. After the compression procedure - Fastone will provide a report on how much hard disk space has been saved.
2. XnVew
A very popular and convenient program for working with photos and pictures. By the way, I edited and compressed the pictures for this article in XnView.
Also, the program allows you to take screenshots of a window or a certain part of it, edit and view pdf files, find similar pictures and delete duplicates, etc.
1) To compress photos, select the ones you want to process in the main window of the program. Then go to the Tools / Batch menu.
2) Select the format into which you want to compress the pictures and press the start button (you can also set the compression settings).
3) The result is rather awkward, the picture is compressed by an order of magnitude.
Was in bmp format: 4.63 MB;
Now in jpg format: 120.95 KB. "By eye" the pictures are practically the same!
3. RIOT
Another very interesting program for compressing images. The bottom line is simple: you open any picture (jpg, gif or png) in it, then you immediately see two windows: one is the original picture, and the other is the output. The RIOT program automatically calculates how much the picture will weigh after compression, and also shows you the compression quality.
What else captivates in it - the abundance of settings, pictures can be compressed in different ways: make them clearer or turn on blur; you can turn off color or only tints of a specific color range.
By the way, a great opportunity: in RIOT you can specify what file size you need and the program will automatically select the settings and set the image compression quality!
Here's a small piece of work: The picture was compressed to 82KB from a 4.63MB file!
Online services for compressing images
In general, personally, I do not really like to compress images using online services. Firstly, I think it takes longer than a program, secondly, online services do not have so many settings, and thirdly, I would not like to upload all pictures to third-party services (after all, there are also personal photos that you show only in close family circle).
Very often there is a need to reduce the size of a JPG file - photos, scanned documents, other images.
Why you need to reduce file size
This allows you to significantly save disk space when storing archives, to speed up the process of transferring image files by e-mail. It is often necessary to bring a photograph to the minimum volume required by some programs, above which photographs and drawings are simply not accepted. The first way to reduce the memory footprint of an image is to convert it to the JPG format, which itself is already a compressed image. But this is not enough. Let's figure out how to reduce the size of a JPG file.
Reducing file size in Paint.NET
The Paint.NET software product (not to be confused with the standard paint editor for Windows operating systems) is freely distributed on the Internet. It "weighs" a hundred times less than the widely used "Photoshop", downloads quickly and takes up almost no disk space. The presence of an understandable interface in Russian, the ability to quickly change the size, format and resolution of graphic files gives it the right to take its rightful place among your constantly used tools.
How to reduce JPG file size using this program? It's very simple - run the program, drag and drop the edited file onto its working field with the mouse. In the main menu of the application, select "Image" - "Resize". In the window that appears, adjust the resolution according to your preferences. Make sure the "Maintain aspect ratio" checkbox is checked. Click "OK".
To change the format and quality level of the picture in the main menu, select "File" - "Save As", specify a new name, select press "OK". Specify the level of picture quality. When the level changes in the range of 95 - 100%, the visual perception of the image remains almost unchanged. This can be seen in the preview window to the right of the menu, where the final file size is also highlighted. After selecting the desired value for the quality (and volume) of the image, click "Save". Job is done.
How to reduce the size of a JPG file in Photoshop
Different versions of Adobe Photoshop allow you to reduce the size of images without losing their quality. This is especially important when saving photos for publication on the web. After loading the photo file into the program, correct its color rendition, contrast and saturation, if you think it is necessary. Then go to resizing: select menu item Image -> Image Size. The current dimensions of the image will appear in the window. To change them, enter new values in the Width and Height fields, you can only enter one of them - the second value will change proportionally. Then select the "Save For Web" option from the "File" menu.
In this case, the application will independently perform optimization of the photo for publication on the network, reducing its disk volume at the sizes you specified.
Select JPEG High when saving a photo. If you are satisfied with the resulting volume, save, if not - change the image quality slider to your liking. After all the manipulations, save the photo under a different name - it is ready for publication.
Working with the PicPick editor
You can resize or resize your JPG file with PicPick image capture. It is also freely available on the Internet. The possibilities of this application are wide. It allows you to capture the entire screen or part of it, add inscriptions and drawings to the image, combine different fragments of images, convert the format of pictures and many other functions.
Resizing images is achieved as follows: load the image, for example, by selecting the Open menu item. In the Image menu, select Resize and in the drop-down menu - Image Resize / Zoom. There are two options here: resize as a percentage (either increase or decrease), or change the number of pixels along the width or length of the image.
In the latter case, if the “Keep aspect ratio” checkbox is checked, it is enough to change only one of the dimensions, the other will change automatically. It is also possible to resize the image to one of the most common sizes by selecting the required one in the lower form window. Click OK. Save the result in the right place, in the required format and under the name you need.
We hope that after reading this article, your question will forever be resolved - how to reduce the size of a JPG file - and you will be confident that you will be able to perform this simple task in relation to your graphic files at any time.
