Make a PNG Square
Crop an image to a perfect square by trimming the longer sides equally from the centre — the fastest way to get a square avatar or a uniform thumbnail. Drop one file or a batch; it all runs in your browser, nothing uploads.

How it crops
The tool takes the shorter side as the square's size and crops the longer side evenly from both ends, keeping the centre of the image. A 1600×900 photo becomes 900×900, losing equal strips from left and right. Nothing is stretched — the result is a true, undistorted square.
