This tool preselects a 256x256 square. You can crop to fill the square, fit inside with background space, or switch output formats.

The size is useful for small avatars, interface icons and lightweight thumbnail images.

ResizeKit performs the resize in browser memory and does not upload your image.

Very detailed images lose detail at 256 pixels. Start with a clear, centered source image when possible.

Is 256x256 good for avatars?

Yes. It is a common compact square size for avatars, thumbnails and small UI images.

Will details be lost?

Fine details may become hard to see at 256 pixels. Use a clear centered source image.

Does ResizeKit store the image?

No. The tool processes it locally and does not store files.
