Can I set each corner to a different value?

Yes, that's the core feature — each of the four corners is independently adjustable rather than one uniform radius applied everywhere.

Can I create an elliptical (non-circular) rounded corner?

Yes, CSS border-radius supports separate horizontal and vertical radius values per corner, and this tool exposes that for more organic, non-uniform shapes.

Does it show a live preview as I adjust each corner?

Yes, you see the actual shape update in real time as you adjust each corner's value.

Does Border Radius Generator upload my files to a server?

No. Border Radius Generator runs entirely in your browser using on-device processing, your files never leave your device.

About this tool

Setting different corner radii on each corner of an element — for an asymmetric, organic shape rather than a uniform rounded rectangle — means writing out all four border-radius values correctly, which is easy to mix up without a visual reference. This tool lets you design per-corner CSS border radii visually and copy the generated code, letting you see the shape as you adjust each corner instead of guessing at four separate values.
