People upload photos to pages on social networks, to their websites, open topics on forums, send to friends and relatives via email, etc. Photos taken with modern cameras take up a lot of space on various media.
Users often face the question: “ how to compress a photo?", because the "large weight" of the image causes the following inconveniences:
- The problem of traffic - there are still countries and cities in the world where you can only use wireless Internet, accordingly, it is charged according to the number of bytes downloaded, so photos need to be compressed so that a person can download them if necessary, and not spend all the traffic on one image;
- Loading speed of web pages – even those users who are connected to a high-speed Internet will have problems loading “heavy” photos, that is, the entire page will be loaded, and the photo will still take some time to load. You also need to remember about loading the page on devices using mobile Internet, the speed of which is low, and too heavy photos slow down this process even more;
- Size restrictions - social networks and various sites set restrictions on the size of uploaded photos - this is necessary for their normal functioning;
- Original size - photographs that take up a lot of space on storage media are actually several times larger in size than the one in which they are displayed on the screen, which causes various incidents with downloading to/from the Internet.
To avoid such problems, you need to compress photos for the Internet. For personal use, that is, viewing on your PC or laptop, this is not necessary.

Resizing an image in a graphics editor is not a difficult task. However, if you need to process one hundred or two hundred files, there is a desire to automate this process. Photoshop's batch processing mode can help with this.
You will need
- - Photoshop program;
- - files for processing.
Instructions
Prepare your photos for processing. To do this, create a new folder and move the files you are going to shrink into it. Create another folder in which you will save the processing results.
Start writing down the sequence of commands that will be used to process each . To do this, use the Create new action button, which is located at the very bottom of the Actions palette. If you do not see this palette in the program window, open it using the Actions option from the Window menu.
Enter the name of the action you are recording in the Name field. This is not necessary; by default, the program will name the created sequence of actions Action 1, but a more specific name will allow you to later freely navigate the created actions. Click on the OK button.
Start recording the action itself by clicking on the Begin recording button. It's a round icon at the bottom of the Actions palette.
Follow the sequence of commands needed to resize a photo. In other words, open one of the files whose size you need to reduce using the Open option from the File menu, call the image size settings window using the Image Size option from the Image menu, enter new values for the image size and resolution and click OK.
Save the file to the folder you created for the processed photos using the Save As option from the File menu. Close the saved image window.
Stop recording the action by clicking the Stop recording button in the Actions palette.
Configure batch file processing options. The processing settings window is opened by selecting the Batch option from the Automate group of the File menu. In the window that opens, select the name of the just recorded action from the Action drop-down list.
Specify the files that need to be processed. To do this, select Folder from the Source list, click the Choose button and specify the folder where the photos are located.
Specify a location to save processing results. Do this by selecting the Folder option from the Destination list and clicking the Choose button. Check the Override Action “Save As” Commands checkbox. Without this checkbox, you will have to manually confirm the file saving settings for each image.
Start batch processing by clicking the OK button.

The number of pixels per inch is one of the indicators of image quality. You can reduce their number in different ways, but this does not have the best effect on image quality.
You will need
- - graphics editor.
Instructions
Open the image in which you want to reduce the number of pixels using an advanced graphics editor. Select from the editing functions to resize the image and select a smaller pixel value.
Please note that reducing the number of pixels in a graphic image results in loss of quality. It is best to save the image separately in its original size, since it is impossible to improve the image quality by increasing the number of pixels.
If you need to reduce the size of an image to a certain size while maintaining quality, open it through the Paint program, which is a standard tool in the Windows operating system. Next, save a copy of the image and check if its size has changed. In this case, Paint simply erases from the file additional information about it, which occupied a certain proportion in its overall size.
In the case when you need to change the number of pixels down without changing the image size, use the compression function in graphic editors. Please note that this action will result in loss of quality, but will reduce the weight of the file itself. In this case, it is also not recommended to have only one copy of the image, since it will no longer be possible to restore it.
Photoshop tools are designed to make your life easier. And if you need to resize several images at once, then we have a solution for you! Find out in this short tutorial.
When There Is More Than One...
Resizing one image in Photoshop is easy, but what if you need to resize 10, 50, or even 100 images? You can process everything individually, but this will take up a lot of your precious time, which you could spend on solving other creative problems.
In this tutorial, you will learn how to resize multiple images at once by creating a custom one and using the function Automation > Batch Processing(Automate > Batch).
If you're new to Photoshop and need a very quick fix for this task, choose one of our many Resizing Actions on GraphicRiver.
1. How to Setup Corresponding Folder
In this tutorial we will use the function Automation > Batch Processing(Automate > Batch), which will allow us to resize several images in a directory. Therefore, it is important to make sure that you select the correct folders, one where the original images are stored and the second where the images will be saved after resizing.
First, create two New Folders on your computer. Name the first one Original Images(Original images) and second Resized Images(Modified images).
Make sure all the photos you are going to change are in the first folder. Remember that this step is required. You can now point Photoshop to a directory where you want to edit all of your images before saving them to a second directory. Now let's move on to creating a Photoshop Action to accomplish this task.
2. How to Create a New Set of Operations
This Photoshop Action is a quick and easy way to change your images in seconds. And as an instructor, I find it very useful when I need to prepare multiple images for an article or lesson, so I will create a treatment just for this case.
Step 1
After you have created the directories, open Adobe Photoshop and go to the panel Operations(Actions) via menu Window > Operations(Window > Actions).
Now go to File > Open to open one image from your catalog. Here I will use this stock photo from Pixabay. Its original size is 960 x 635 px.
Step 2
In the panel Operations, click on the button Folders And Create a New Set for your action (for operation). Give it a name - Resizing Action, And click OK.
3. How to Create a Photo Resizing Action in Photoshop
Step 1
With the folder highlighted, click on the button Liszt, to Create a New Operation. Since I'm going to use this action to create appropriately sized images for my Envato Tuts+ post, I'll call this action Tuts+ Post Images. And you give a name that will correspond to your task. When you are done with this, click the button Record to start recording your transaction.
Step 2
While you are recording, go to Image > Image Size(Image > Size) and change the width and height as per your requirements. Our articles are at least 850 px to the width, so I'll adjust the width to that size.
Step 3
But we're not done yet! Since the image has been resized, it's time Save file. Go to File > Save As(File > Save As, and find the save directory Modified Files. When you find the directory, be careful not to change the file name before clicking Save. Then select Quality the image you would like for these jpegs. I need the file size to be smaller, so I choose Medium quality - 6
.
Step 4
The last step for this action is a very important one. While the recording is still active, go to File > Close(File > Close) or click Control-W to close the Photoshop file. This should be your last step while recording this operation and you can now click Stop in the panel Operations. If you don't enable the last step, Photoshop will load all of your images into the folder without closing any of them. And depending on how many of them you have, your computer may start to glitch or freeze.
4. How to Create Automation
Step 1
Now you can use the action you just created to change multiple files in a folder. To do this, go to File > Automation > Batch Processing(File > Automate > Batch).
Step 2
In installations Batch Processing, select Operation Set, which you just created, as well as Operation which one do you want Execute. Before you click OK, Select the folder that contains the images you want to change. Because the created operation saves the images in the folder Resized Images, all your new images will appear there.
That's all! This action will now be applied to every image in the folder, and each file will be closed before a new one is loaded. Enjoy the action by using it in your future projects, or customize it to suit your needs.
Conclusion
By spending some time creating this little action, you will now significantly speed up the processing time of your images in your future projects. I hope you enjoyed this short tutorial! Let me know in the comments if you have any questions.
