The Best Free CSS Border Radius Generator
Rounded corners are a cornerstone of modern web design. The border-radius CSS property lets you soften sharp edges on buttons, cards, images, and containers. However, creating unique organic shapes with different radius values per corner can be tricky to visualize. The GadgetsFocus free online CSS Border Radius Generator makes it simple with a live visual preview.
How to Use
  1. Use “All Corners”: Drag the top slider to set all four corners at once (perfect for simple rounded rectangles or circles).
  2. Fine-tune Individual Corners: Adjust each corner independently using the four sliders below to create asymmetric shapes and organic blobs.
  3. Live Preview: The purple shape updates in real time as you drag the sliders.
  4. Copy CSS: Click “Copy CSS” to copy the generated border-radius property.
Tips for Great Rounded Corners
  • Set all corners to 50% to turn a square into a perfect circle.
  • Use subtle values like 8-12% for card containers and input fields for a polished, modern look.
  • Create unique blob shapes by giving each corner a different high value (e.g., 30% 70% 50% 20%).
