About CSS Border Radius Generator
OptiPix CSS Border Radius Generator lets you design rounded corners visually. Control all four corners together or individually (top-left, top-right, bottom-right, bottom-left). Link or unlink corners — when linked, all corners move together. In advanced mode, set both horizontal and vertical radii per corner for the full 8-value CSS syntax that creates organic blob shapes. Preview the border radius on a customizable box in real time. Choose from shape presets: Circle (50%), Pill (9999px), Squircle (iOS app icon ~22%), Organic Blob, Leaf, and Drop shapes. Copy the generated CSS. Customize the preview box size, background color, and border. Everything runs locally in your browser.
How It Works
The tool constructs CSS border-radius strings from the slider values. In simple mode, it generates 'border-radius: TL TR BR BL'. In advanced mode, it generates the full 8-value syntax with horizontal and vertical radii separated by a slash.
