Common questions

What's the difference from just setting one border-radius value?

A single value rounds all four corners equally. This tool lets you set each corner independently, useful for effects like a card with only its top corners rounded, or an asymmetric "blob" shape.

What units does this use?

Pixels. If you need percentage-based radii (for perfect circles/ellipses regardless of element size), you'd adjust the generated CSS manually, swap px for % on each value.

Is this sent anywhere?

No, the preview and CSS are generated entirely in your browser. Nothing is uploaded.
