Rounded Corners

Clip images to a radius or a full pill.

Loading tool

Turn a square mark into an app icon shape or a circular avatar. Clipping is local; the download keeps alpha.

How to use this tool

Choose a file on this device. Pick an image from your computer or phone. The file stays in this browser tab.
Set size or quality. Use the sliders and format controls. A preview is shown when the tool can make one.
Download the new file. Save the result. The original on disk is not overwritten.

Pixels or a percent of the shorter side. 50% on a square source yields a circle.

Files never leave the device. The clipped bitmap is not stored after you leave.

Why did JPEG download look square again?

JPEG cannot store transparency. Export PNG or WebP.

Can each corner have a different radius?

Yes. Unlock corners to set them independently.

Does this add a border?

Optional stroke sits inside the clip. Turn it off for a clean mask.

Will CSS border-radius look the same?

Close, but CSS radii follow the box model. This bakes the clip into pixels.

Can I round a screenshot of a window?

Yes. Match the OS radius if you want the chrome to look native.
