What is Rounded Image?

Round the corners of any image and save it as a transparent PNG. Upload a picture, set the corner radius (a percentage of the shorter side — 50% gives a circle), preview the result and download. Processing is fully local.

How Rounded Image works

The image is drawn onto a canvas, then a rounded-rectangle clipping path is applied so the corners become transparent. The result is exported as a PNG to preserve that transparency.
