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 CSS
The CSS is generated live in your browser as you adjust the controls, so there is nothing to install and nothing is uploaded. Copy the ready-to-use declaration straight into your stylesheet, tweak the values to taste, and it will render exactly as it does in the preview here.
