PowerToys Image Resizer is one of the most useful features in Microsoft's free utility collection. It adds a "Resize pictures" option to the Windows right-click context menu. Select a photo in File Explorer, right-click, pick a size, done. No app to open. No browser tab. Just right-click.
Here is how to set it up, configure custom size presets, and when a browser tool is a better choice.
Installing PowerToys and Enabling Image Resizer
PowerToys is free from Microsoft. Two ways to install:
Option 1: Microsoft Store — search "PowerToys" in the Microsoft Store app, click Install. Automatic updates.
Option 2: GitHub — download the latest release from github.com/microsoft/PowerToys. Manual updates, but you get the newest version immediately.
After installation:
- Open PowerToys Settings (system tray icon or search "PowerToys")
- Find "Image Resizer" in the left sidebar
- Make sure the toggle is ON (it should be by default)
Now right-click any image file (or multiple selected images) in File Explorer. You will see "Resize pictures" in the context menu. On Windows 11, you may need to click "Show more options" first to see it in the classic context menu.
How to Use PowerToys Image Resizer
The workflow is simple:
- Select one or more images in File Explorer
- Right-click > "Resize pictures" (or "Show more options" > "Resize pictures" on Windows 11)
- A dialog appears with size presets: Small (854px), Medium (1366px), Large (1920px), Phone (320px)
- Choose a preset or click "Custom" to enter specific dimensions
- Options: resize original file, create a new copy, or replace the original
- Click "Resize" — done
Batch resizing is the killer feature. Select 200 photos in a folder, right-click, resize — all 200 are processed in seconds. No other free tool on Windows makes batch resizing this fast.
The resized files are saved alongside the originals with a size suffix by default (e.g., "photo (Small).jpg"). You can change this naming pattern in PowerToys settings.

The default presets (Small/Medium/Large/Phone) may not match your needs. To add custom sizes:
- Open PowerToys Settings > Image Resizer
- Scroll to "Image sizes" section
- Click "Add new size"
- Name it (e.g., "Instagram Post"), set dimensions (1080 x 1080), choose resize mode
Useful custom presets to add:
- Blog — 1200 x auto (width only, height proportional)
- Email — 600 x auto
- YouTube Thumbnail — 1280 x 720
- Instagram Post — 1080 x 1080
- Print 4x6 — 1800 x 1200
Resize modes: "Fill" forces exact dimensions (may crop). "Fit" scales to fit within dimensions (may leave blank space). "Stretch" forces exact dimensions (may distort). "Fit" is safest for most uses.
When PowerToys Is Not Enough
PowerToys Image Resizer is excellent for batch work on Windows, but it has gaps:
- Windows only — Mac, Linux, Chromebook, and phone users need something else
- No format conversion — a JPG stays a JPG, a PNG stays a PNG. You cannot convert during resize.
- No quality slider — you cannot control JPG compression level
- No preview — you do not see the resized image before saving
- Windows 11 context menu — the extra "Show more options" click is annoying for some users
For these situations, a browser tool fills the gap. The WildandFree resizer offers format conversion (JPG to WebP, PNG to JPG), a quality slider, and works on every platform. It processes locally just like PowerToys — no server upload.
The ideal setup for Windows power users: PowerToys for quick batch work from File Explorer, browser tool for one-off resizes that need format conversion or quality control.
PowerToys vs Browser Tool — Quick Comparison
