When you need a 100x100 pixel image

A 100x100 pixel square image is the standard for small profile pictures, forum avatars, directory listings, and thumbnail icons. Many platforms, admin panels, and content management systems require exactly this size for user photos or product thumbnails.

Because the output is very small, the source image quality matters less than the cropping. Center the most important part of the image — usually a face or logo — and the tool handles the rest.

This tool outputs a square crop at exactly 100x100 pixels. If your source image is not square, it will be cropped to a square aspect ratio before resizing.
