When to use this tool

Decorative rounded corners for app icons, social-media avatars, marketing imagery, or thumbnails. The radius is uniform across all four corners.

Avatar / profile pic. Set radius to half the image width for a circle.
App icon. Match the platform's corner radius (e.g. iOS uses ~22% of icon size).
Card thumbnails. Slim radius (8-16px) for a polished look.
Decorative blog images. Rounded corners read as more designed than hard-edge.

How big should the radius be?

Depends on intent. 8 px for subtle. 24 px for clear. ~22% of image width for iOS-style. Half the smaller dimension for full circle.

Output is always PNG?

Yes — to preserve transparency at the corners. Convert afterward via PNG → JPG if you need a flat-background JPG.
