Why is the output PNG?

The corners need to be transparent and JPG has no transparency, so results are always PNG.

It is centre-cropped to a square first and then to a circle, so nothing gets stretched.

⭕Round Corners Online - Make Rounded or Circle Images

Give your pictures rounded corners, or crop them into a perfect circle for an avatar. Everything outside the shape becomes transparent and the result is saved as a PNG, ready for websites, slides, posters and social profiles. The radius is set as a share of the short side, so a whole batch comes out consistent. Everything runs locally and images are never uploaded.
