— what it is

Organic blob shapes have become a staple of modern web design — soft, irregular backgrounds and dividers that break up the geometric rigidity of a grid layout. Generating them manually would mean wrestling with cubic Bézier curves. The CSS Blob Generator handles it automatically: adjust the size, complexity, and colour, watch the shape update live, and copy the SVG or CSS background code.

Web designers creating landing page backgrounds, section dividers, or decorative elements who want a distinctive organic shape without hand-editing SVG paths. Also useful for generating multiple blob variants quickly when iterating on a design.

— frequently asked questions

What is a blob shape?

An organic blob is a smooth, irregular rounded shape — not a circle or polygon. They're used in web design to add a natural, non-geometric visual element.

Can I get the same blob twice?

Each generation is random by default. To save a shape, copy the SVG code after generation.

Can I animate the blob?

You can add CSS animations to the SVG output manually — morphing blob animations require JavaScript or additional CSS.

What's the difference between SVG and CSS background output?

SVG is a code block to embed in HTML. CSS background uses a data URI to reference the shape as a background image.

Will the blob look the same on all screens?

Yes — SVG shapes scale losslessly to any size.
