Round the Corners of an Image

Why round an image's corners?

Rounded corners are everywhere in modern design — app icons, cards, avatars, thumbnails, UI mockups. Softening the sharp 90° corners of a photo makes it feel friendlier and more polished, and it helps an image sit comfortably inside rounded buttons, cards, and containers.

This tool rounds all four corners by the radius you choose, set as a percentage so it scales with the image. With a PNG or WebP output, the area outside the rounded corners is kept fully transparent, so the image drops onto any background cleanly. Choose a solid background colour instead if you'd rather fill the corners.

How to round the corners of an image

1. Open your image. Drag it onto the tool, choose a file, or paste it.
2. Set the radius. Drag the rounded-corners slider until the curve looks right. Keep the border at zero for corners only, or add a border too.
3. Keep it transparent and download. Leave the background transparent (PNG/WebP) so the corners cut out cleanly, then click Download.

Keep a transparent output

For rounded corners to actually cut out, export as PNG or WebP with the background set to Transparent. If you export as JPG — which can't store transparency — the corners are filled with your chosen background colour instead.
