Free Border Radius Generator — Complex CSS Corner Radii

Generate complex CSS border radius values with independent control over every corner. The UtilixVerse border radius generator builds anything from crisp square cards to perfectpills, squircles, and organic blob corners — with live preview and copy-ready CSS in both pixels and percentages.

Four corners, infinite shapes

Unlike simple rounded-corner tools, this generator gives each of the four corners its own slider, unlocking asymmetric shapes that feel modern and organic. Use the Organic Seed for deterministic hand-drawn-looking corners, Equalize to flatten differences, and presets to jump straight to a finished look. The generated shorthand follows the CSS spec exactly:border-radius: tl tr br bl.

Border Radius Generator FAQ

Common questions about generating CSS border radius values.

How do I create a custom border radius?

Drag the four corner sliders (top-left, top-right, bottom-right, bottom-left) to shape the element, or use the 🎲 Random Shape button for organic "blob-like" corners. Presets like Small, Pill, Squircle, and Blob give instant starting points, and the unit toggle switches between pixels and percentages.

What is the difference between px and % for border-radius?

Pixels are fixed and predictable; percentages are relative to the element size. A 50% radius turns a square into a perfect circle, while large px values create rounded "pill" shapes. The generator supports both and shows the exact CSS syntax, including the four-value shorthand order: top-left, top-right, bottom-right, bottom-left.

What is an organic or blob border radius?

An organic radius gives each corner a different value, creating irregular, hand-drawn-looking shapes used for avatar placeholders, badges, and playful cards. The Organic Seed field generates deterministic asymmetric corners — the same seed always produces the same shape.

Can I apply border radius to images?

Yes — apply the generated class to any <img>, div, button, or container. Combine it with our Box Shadow Generator for complete card styling, and use the generated values in any CSS framework via arbitrary values.
