About Border Radius Generator

The Border Radius Generator lets you round each corner independently with sliders and a live preview, then copy the exact border-radius CSS — including the four-value and eight-value syntax for organic blob shapes. It takes the trial and error out of getting corners just right. Everything runs in your browser with nothing uploaded. Add depth with the CSS Box Shadow Generator, and backgrounds with the Gradient Generator.

Frequently Asked Questions

Can I round corners individually?

Yes. Each corner can be set separately, and you can use the horizontal and vertical radius syntax to create asymmetric, blob-like shapes, all reflected in the live preview.

Is the output standard CSS?

Yes. The generated border-radius value is standard CSS you can paste straight into your stylesheet to reproduce the exact shape shown in the preview.

Is Border Radius Generator free to use?

Yes. Border Radius Generator is completely free with no sign-up, no subscription, and no usage limits. Every tool on CodeUtilityKit is free forever.

Is my data safe when I use Border Radius Generator?

Absolutely. Border Radius Generator runs entirely in your browser. Your input is processed locally with JavaScript and is never sent to, stored on, or logged by any server — so it is safe even for private or sensitive data.
