Need to quickly resize a group of pictures in Windows 10? With Microsoft PowerToys utility, you can do this directly from File Explorer with a right click – no need to open an image editor. Here’s how to set it up and use it.

What is PowerToys Image Resizer?

Easy bulk image resizing is just a few clicks away in Windows 10 thanks to the “Image Resizer” module included with Microsoft PowerToys, a free suite of utilities for Windows 10 users.

When fully configured, Image Resizer allows you to right-click a set of images in File Explorer (or on your desktop) and resize them to a preconfigured or custom size. The resulting resized images are written to the same location as the source images.

Step 1: Install PowerToys and activate the image resizer

First, if you don’t already have it (it’s not installed by default), you’ll need to download Microsoft PowerToys on the Microsoft website.

The latest version is usually listed at the top of this download page. Look for an EXE file such as “PowerToysSetup-0.27.1-x64.exe ”. Download and run this file.

Once the installation process is complete, launch PowerToys from your desktop or the start menu and click on “Image Resizer” in the sidebar. Then make sure that the “Enable Image Resizing” switch is in the “On” position.

Then you can close the PowerToys window and try resizing the images in File Explorer.

Step 2: Resize Pictures in File Explorer or Desktop

With Image Resizer enabled, resizing images is just a few clicks away. First, find the images you want to resize in File Explorer or on your desktop.

Sample images in Windows 10 File Explorer.

Select a group of images with your mouse, then click on it with the right mouse button. In the menu that appears, select “Resize images”.

An Image Resizer window opens. Choose the desired image size from the list (or enter a custom size), select the desired options, and click “Resize”.

After that, the resized images will appear in the same folder as the source images. You can do this with as many images as you want. Very convenient!

Optional: Configure Image Resize Settings

If you want to configure the image sizes listed in the Image Resizer window that appears when you resize the images, launch PowerToys, then click “Image Resizer” in the sidebar.

On the Image Resizer options page, you will see three main sections that allow you to configure how Image Resizer works.

First, you will see a section called “Image Sizes” which defines a set of profiles that you will choose when you run Image Resizer (There is also an option for a custom size when you run it.). Here you can edit any of the included profiles or add your own predefined custom size.

Then you will see an “Encoding” section. By default, Image Resizer will save the resized image in the source file format, but if it fails, it will save the image in the format specified in the “Fallback encoder” option here. You can also specify the JPEG quality level, PNG interlacing, or TIFF compression.

Finally, the “File” section allows you to specify the file name format of the resized images. The default includes the name of the original file plus the size you selected.

Technically, you don’t need to change any of these settings to use Image Resizer, but it’s good to familiarize yourself with them in case you want to change how they work later. Have fun resizing!
