CSS Blob Generator
Generate organic blob shapes with border-radius CSS.
Organic blob shapes in CSS
Perfectly round corners can feel rigid; organic, asymmetric “blob” shapes add a soft, modern touch to avatars, backgrounds, and decorative elements. This generator produces those shapes using multi-value border-radius, with a live preview.
Hand-tuning eight border-radius values to get a pleasing blob is tedious, so a generator that lets you shape it visually saves time. Adjust until the form feels right and copy the border-radius CSS into your project.
Copy-ready blob CSS
The organic shape is an asymmetric border-radius with eight values, copied as a single property. It is generated in your browser, nothing uploaded.
