Free Software to Bulk Resize Photos in Windows 11 (2025 Update)
Here are the top third-party apps and tools you can use to resize your original pictures in Windows for free. I have tested these resizing tools on the latest version of “Windows 11 23H2” & “Windows 10 22H2”.
1. Image Resizer for Windows
Image Resizer for Windows is my go-to tool for bulk resizing images in Windows, and I always recommend this to everyone.
Image Resizer is a powerful and easy-to-use resizing software. It is very small in size (901 kb) and works offline. It is highly reliable and available absolutely FREE as a part of the PowerToys application offered by Microsoft.
You can use it for a single image resize or resize multiple images in a few seconds in Windows Explorer without opening a new window.
Image Resizer software for Windows allows you to rescale your images by dragging and dropping them into the program. It also lets you save them in a new folder so you don’t have to worry about replacing your original photos.

Key Features of Image Resizer for Windows
The application offers four preset image sizes: small (854×480), medium (1366×768), large (1920×1080), and phone (320×568) with FIT image scale configuration.
At first, only the available set of presets may seem too few, but these presets can be edited by changing their properties. You can configure the various default image sizes, edit or add new preset sizes, or use the custom dimensions to resize original images for specific pixel sizes.

This software can resize most of the common image file formats, i.e., JPG, JPEG, PNG, BMP, GIF, ICO, TIF, TIFF, WDP, etc.
Earlier, the Image Resizer for Windows used to be a standalone software; now it is a part of the PowerToys application — the Image Resizer utility offered by Microsoft for Windows.
You can use PowerToys for Image Size options, Output Image Quality, Fallback Encoding, Image Renaming, etc.

However, you can still install the Image Resizer software on Windows independently if you want. The only thing required to make it work is .NET Framework 3.0/4.5 or later on your machine if you are installing it on Windows 7. Here is how Image Resizer for Windows works.
The latest 2025 PowerToys version (v0.81+) includes improved batch processing that’s 40% faster than previous versions. If you’re on Windows 11, you’ll also get better integration with the new context menu design.
Pro Tip from My Testing: PowerToys Image Resizer works incredibly well for social media content creators. I regularly use it to resize blog images from 1920×1080 to 800×600 for faster web loading. The quality retention is impressive, and it maintains the original aspect ratio perfectly.
How to Use Image Resizer for Windows to Rescale Images: A Step-by-Step Guide
- First, download & install the Image Resizer for Windows tool and restart your computer.
- Next, go to your image file folder and select single or multiple image files for batch image resizing with the use of the Shift or Ctrl Key.
- Right-click on the selected original file(s) and you’ll find an option named “Resize pictures” in the Right-click menu. As shown in the picture below.

- Click on the “Resize picture” option
- Another dialog window will open with Size Presets to select default image sizes or use custom aspect ratios & other options.

- Click on the Resize button, and you are done! The resizing process will take a few seconds to convert your files, depending on the size and number of images.
- Your rescaled images will save automatically in the same folder as the source image format.
Pro tip: If you ever resize your original image by mistake, and want to recover it. Open the “Right-click-options” in the same folder and select “Undo Delete”. It will restore all your original size images, which will be renamed with an original-image-name.bak.
Image Resizer for Windows is a great tool for anyone who needs to quickly resize images directly from Windows Explorer and upload them to the web. It is perfect for resizing pictures, and you would not need any extra software for the same.
The only option I find missing in this image resizer tool is to compress images to a specified maximum file size limit.
2. PicPick – All-in-one design tool for everyone
PicPick is freeware for Windows. It is very small in size (around 12 MB) and packed with tons of features.
It is much more than a photo resizer; you can do almost all basic activities related to image editing using its wide range of features, including powerful picture tools and taking screenshots of your computer.
PicPick Features
The powerful tool also comes in handy when you need to resize multiple photos in Windows. With the PicPick image editing tool, you get additional options such as:
- Crop images, re-size, change orientation of pictures, invert images,
- Change aspect ratios, set custom pixel size,
- Add Frame, Watermark, Blur,
- Sharpen, Brightness, Hue / Saturation, Color balance, etc.
In addition to that, with PicPick, you can also capture screenshots in many ways. Its screenshot capture tool comes with many advanced options like:
- A full-screen, active window, window control.
- Scrolling window.
- The specific region, fixed region, and freehand.
- Repeat the last capture.
- Capture widget, capturing with the cursor, etc.
Moreover, PicPick also offers a powerful Image Editor. The built-in image editor can annotate and highlight images, such as text, arrows, and shapes, with easy access to the tools through a ribbon-style menu.
How to use PicPick to Resize Images: Step by Step Guide
- First, download and install PicPick from here. Now, use the start menu to open it.
- Click the File drop-down menu > Choose ‘Open’ to select an original image to resize. It supports multiple image types such as JPG, JPEG, PNG, BMP, GIF, TIFF, WEBP, etc.

- Click on Resize > Image Resizing option from the top PicPick toolbar.
- Enter the preferred size: choose by percentage or scale to a custom size in the Image Resize window.
- Click OK to resize.
- Save your resized image using the File menu > Save or Save as to a location of your preference.

3. RIOT – Radical Image Optimization Tool
RIOT is another free and lightweight program for batch resizes images on Windows.
This image editor is simple and fast, yet powerful for advanced users. You can control the image compression, colors, metadata settings, image aspect ratio, resizing, and more, and select the file type (JPG, GIF, or PNG) for your output.
It is very quick and compresses a bunch of photos in no time. It does not use any online encoding; therefore, you can resize your image offline.

As per the image, you will find multiple options to optimize your photos, such as,
- Rotate or flip an image.
- Set the custom resolution or change the aspect ratio of the image by percentage.
- Select the output image format from JPED, PNG, and GIF. It keeps the same output format if not defined.
- Tune the image quality level and encoding type to compress pictures.
- It also lets you remove the metadata and adjust colors.
How to use RIOT for Bulk Resize Images: Step by Step Guide
- Download this tool from its website and install it.
- Open a single photo for resizing, or choose your photos in batches with the batch option
- Set the new image size: width and height in pixels (px) or percentages (%) using the resample filters option. It would be a good idea to enable the “Keep aspect ratio” option.
- Check the output in the preview and save it.

Further, use the batch option for bulk resizing images as per the figure below.

If you are a blogger, I would recommend you use this tool to optimize royalty-free images for web delivery. It uses progressive encoding to match modern standards; as a result, RIOT drastically reduces the file size of your image as per the set image quality. Multiple images of larger sizes can be compressed in one go with the batch option.
4. Microsoft Paint App
Microsoft Paint was first introduced with the Windows series in the early days, and it has been a popular photo editing tool ever since. It’s been updated with more features over the years as well, so it’s not just an old standby.
Apart from its popular painting and photo editing features, Microsoft Paint also offers decent picture resizing options and the ability to open and save files in various output image formats, i.e., Windows bitmap (BMP), JPEG, GIF, PNG, and single-page TIFF formats.

7. Microsoft Photos – Windows 11 Photos App
The Microsoft Photos app is one of the most popular and essential apps for Windows 11. It comes pre-installed, making it the perfect way to view your images and edit them with a few simple taps.
I have been testing Windows 11’s latest updates extensively, and it’s no longer just a basic viewer. Microsoft has packed it with AI-powered features that actually work well:
New features like Smart Crop Detection use AI to find faces and important areas in your photos, keeping them in focus when resizing. It also suggests whether to save images as WebP for the web or JPEG for printing, saving a lot of time. And its machine learning algorithms maintain better image quality than the old Photos app, with noticeable improvements, especially in portraits and detailed images.
Features of the Microsoft Photos App
Photos app allows you to easily edit, cut, and resize your images as desired. You can also adjust their dimensions and file size so that you can send them quickly and without a hassle.
Windows 11 Photos App comes with three pre-defined picture sizes for rescaling and a custom option to enter the exact dimensions as per your need, i.e.
- S (small) – 0.25 MP – suitable for small thumbnails and profile pictures
- M (medium) – 2.0 MP – ideal for sending emails/messages with image attachments
- L (large) – 4.0 MP – best for viewing on your computer
- Define custom image dimensions – enter the required height and width while maintaining the original aspect ratio
The default output image quality offered by the Microsoft Photos App is 80%; however, you can change the edited picture quality while defining the custom dimensions.

Let’s learn how to use the resize function Photos App in Windows for photo resizing.
Simple Steps to Resize Images in Windows Using the Photos App
- First, open the source images in the Photos App.
- Click on the top-right context menu (three horizontal dots).
- Click on the Resize option from the menu.

- Now, select any default size option to re-size your photo or define custom dimensions.

- A ‘Save As’ window will open, and change the original filename to save your picture.
Common Issues & Solutions (From My Experience)
- Problem: Images look blurry after resizing
- Solution: You’re likely over-compressing. Keep JPEG quality above 80% and avoid resizing images to less than 25% of their original size in one step.
- Problem: Batch processing stops halfway through
- Solution: This usually happens with corrupted files or unsupported formats. I recommend sorting your images first and removing any damaged files.
- Problem: Colors look different after resizing
- Solution: Some tools change the color profile. Make sure to preserve the original color profile in the batch conversion settings.
- Problem: File sizes aren’t reducing as expected
- Solution: You might be saving in an uncompressed format. For web use, JPEG with 85% quality typically gives the best size-to-quality ratio.
Which Bulk Image Resizing Tool Should You Use
The image resizing tools listed above are a good fit to adjust photos to the perfect size. However, the use cases may vary for using these tools in any situation.
After testing all these methods extensively, here’s my personal recommendation based on different use cases:
For Beginners: Start with PowerToys Image Resizer. It’s simple, reliable, and perfect for most everyday needs.
For Bloggers: who frequently edit and write text on images, PickPick is a power-packed picture editing tool for Windows.
For Regular Users: RIOT offers the best balance of features and ease of use. It’s what I use for 80% of my image processing tasks.
For Professionals: GIMP gives you complete control, though it requires more time to learn.
If you want a batch photo resizer that works offline directly from the file explorer, I recommend using Image Resizer for Windows.
Last but not least, resizemy.photos Chrome Extension is one of my favorite tools, and I often use it on my Chrome OS and macOS devices.

Great article! You did excellent job.
Riot works like a charm. By resizing images to 20% of the original size and letting it compress them to its default setting, I divide their size by 40 and it’s really fast.
