CSS Border-Radius Generator: From Rounded Cards to Organic Blob Shapes
About This Tool
Free CSS border-radius generator — drag sliders to set each corner independently (top-left, top-right, bottom-right, bottom-left) with a live preview box, from simple rounded cards to organic "blob" shapes, then copy the exact `border-radius` CSS. No sign-up, no upload, entirely browser-based. Designers use asymmetric border-radius values to create soft, organic shapes for hero images, avatars, and decorative blobs that stand out from plain rounded rectangles. This tool makes it easy to preview the effect live and fine-tune the horizontal and vertical radius of each corner before copying clean CSS into your project.
