How is the circle cropped?

The tool takes a centred square equal to the image's shorter side and masks it to a circle on a canvas. The area outside the circle is transparent in the exported PNG.

Crop any photo into a circle

Turn any photo into a perfect circle — the standard shape for avatars, profile pictures and team headshots. The tool crops a centred square from your image and masks it to a circle, exporting a PNG whose corners are transparent so it works on any background.

How it works

  1. A centred square is taken from the image, sized to the shorter side so nothing is stretched.
  2. That square is drawn onto a circular clip path on a local <canvas>.
  3. The result is exported as a PNG, optionally resampled to a fixed diameter.
square side = min(width, height)
crop origin = centred, so equal margins are trimmed on the long axis

Behind the circle

By default the corners are transparent. If your destination does not handle transparency well, choose a solid white, black or light-grey background to fill behind the circle.

Everything runs on a local canvas, so your photos are never uploaded.
