About this tool

The corners are cut away in a smooth curve and the cut-off areas become transparent. The slider runs from 0 percent, which leaves square corners, to 100 percent, which rounds the shorter sides completely. On a square picture, 100 percent gives a circle.

Transparent corners need a format that can store transparency. PNG and WebP can. JPG cannot, so if you choose JPG the corners are filled with white, which looks fine only on a white page.

The picture keeps its original pixel size. Only the corners change, so you can drop the result straight onto a coloured background, a slide or a web page.

Practical uses

Profile pictures and thumbnails with a soft look.
App store or social graphics with rounded tiles.
Pictures placed on slides or web pages with a coloured background.

Tips for better results

Around 10 to 25 percent gives a modern, gentle rounding on most photos.
Always choose PNG or WebP if the picture will sit on anything other than white.
For a perfect circle, use the Crop Image to Circle tool, which cuts a centred square first.
