What is CSS Border Radius Generator?
A CSS border radius generator is a visual tool that helps you create rounded corners for any HTML element.
The CSS border-radius property rounds the corners of an element's outer border edge. You can set a single radius for all four corners or specify each corner individually for asymmetric shapes. This tool gives you independent control over top-left, top-right, bottom-right, and bottom-left corners with a live preview. You can also link all corners to adjust them simultaneously. The generated CSS works in all modern browsers without vendor prefixes.
How to use CSS Border Radius Generator
- 1
Adjust corner values
Use the sliders or type values directly for each corner — top-left, top-right, bottom-right, and bottom-left. Toggle the link icon to adjust all corners at once.
- 2
Preview your shape
The live preview box updates instantly as you change values. Watch how different corner combinations create pills, leaves, blobs, and other organic shapes.
