A hundred pixels square is a small avatar and thumbnail size used by forums, chat apps and comment systems. At a hundred pixels a face stays recognisable but fine text vanishes, so this square belongs to avatars and list thumbnails, never to anything a viewer must actually read. Forum software and comment systems lean on it because a wall of hundred-pixel faces loads instantly even on a slow connection. If your source is a wide photo, expect the sides to be trimmed as it fills the little square. It is the size many profile pictures and list thumbnails are actually displayed at. This tool resizes any image to exactly 100×100 pixels and does it entirely in the browser - the picture is decoded, scaled and returned without being uploaded anywhere. Because the target is fixed dimensions rather than a fixed file size, it scales to fill 100×100 and covers the frame where the source is a different shape, so the whole area is used rather than left with borders.
Shape and export choices
- Choose any image of any shape. It is decoded in the browser so the scale reads the original pixels.
- It is scaled to fill exactly 100×100; a source of a different aspect ratio is covered so the whole square is used with no empty bars.
- The 100×100 result appears at true size. Download it from this tab, with nothing sent to a server.

100×100 from any source
If your source is a wide photo, expect the sides to be trimmed as it fills the little square. Whatever you start from, the result is exactly 100×100.
Check the image before download
- Filling a 100×100 square from a non-square source trims the overflowing edges. If precisely what stays matters, crop the image first, then resize.
- Enlarging a source smaller than 100×100 cannot invent detail and will look soft, so start from an image at least 100×100. The output is a JPG and drops the original's metadata such as camera model and GPS, which is usually welcome before sharing.
Questions about Resize Image to 100×100
What if my photo is not square?
It is scaled to fill 100×100 and the overflowing sides or top-and-bottom are trimmed, so the square is fully used with no bars. Crop first to control exactly what remains.
Will enlarging look blurry?
Making a small image 100×100 cannot add detail, so it will look soft. Start from a source at least 100×100 for sharpness.
