CSS Border Radius Generator

Shape corners visually — blobs, pills & elliptical radii.

The CSS Border Radius Generator rounds each corner independently or in sync, supports elliptical radii, includes preset shapes like blob, organic, pill and circle, and outputs production-ready CSS.

What is a CSS Border Radius Generator?

A CSS border radius generator lets you round element corners visually and export the CSS — from simple rounded boxes to pills, circles and organic blobs. Fontily's offers per-corner and elliptical control with a live preview, so you can shape exactly what you need without writing the syntax by hand.

Features

  • Per-corner control, linked or independent.
  • Elliptical radii for soft, organic shapes.
  • Preset shapes — blob, organic, pill, circle and rounded rectangle.
  • Random generator for inspiration.
  • Live preview and copy-ready CSS.

How to Use the CSS Border Radius Generator

  1. Drag the corner sliders, or pick a preset shape.
  2. Switch to Independent to edit each corner separately.
  3. Enable Elliptical for blob-like curves.
  4. Copy the generated border-radius CSS into your stylesheet.

Benefits

Border-radius syntax gets tricky once corners differ or go elliptical. A visual generator lets you experiment instantly, create trendy blob and squircle shapes, and ship clean CSS that renders consistently across browsers.

Use Cases

  • Buttons, cards and avatars with rounded corners.
  • Pill-shaped tags and badges.
  • Organic blob backgrounds and dividers.
  • Squircle app-icon style shapes.

Conclusion

Fontily's CSS Border Radius Generator turns corner shaping into a few clicks, from pills to blobs, with copy-ready CSS. Design above and paste the result into your project — free and instant.
