Open Resize Image to 100×100Where 100×100 is used
User avatars on forums and communities, comment sections, game platform profiles, small thumbnails and favicon-adjacent icons. Some systems even crop to circle, so keep your subject centered with margin.
Square-crop to 100×100
- Open the Resize Image tool.
- Drop your image.
- Set width 100px and height 100px.
- Enable center crop so faces and subjects stay in frame.
- Download.
Square-cropping prevents stretching — the result is a clean, undistorted avatar.
Keep avatars sharp at 100px
Export as PNG for logos and icons (sharp edges), or JPG for photos. At 100px the file size is trivially small, so pick the format that keeps your content crisp rather than the smallest file.

Frequently Asked Questions
Does resizing to 100×100 stretch my image?
Only if the source isn't square. Enable center crop and the tool crops to 1:1 first, then resizes — no distortion.
Is 100×100 too small for a profile picture?
It's the standard for forums and avatars. For modern social networks, use 400×400 and it will be downscaled automatically.
Can I make any image square?
Yes — the crop centers the image and takes the largest possible 1:1 section, preserving the most important central content.
