Blob Shapes tips

🫧

Enable the elliptical (X / Y) toggle for organic blob shapes. Different X and Y values per corner produce asymmetric, hand-drawn-feeling forms.

💡

Random blobs work best when no two corners share radius values. Even subtle asymmetry (e.g., 40px/60px on one corner) reads as intentional.

🎨

Animate the radius values via CSS for morphing blob backgrounds — a popular hero-section effect for landing pages.

🔍

For SVG-precise control over blob shapes, use a tool like blobmaker.app; this generator is best when you want native CSS without extra markup.
