CSS Blob Shape Generator
Generate an organic blob shape as SVG for backgrounds and decoration, and copy the code.
Soft organic shapes
Blobs — soft, irregular, rounded shapes — are a popular decorative element that adds an organic, friendly feel to otherwise rectangular layouts. This generates a random blob as SVG and copies the code, so you can drop a smooth organic shape behind content or as an accent.

Why blobs soften a design
The web's grid of rectangles can feel rigid, and organic blob shapes are a quick antidote — used as a background shape behind an image, a coloured accent, or a mask for a photo, they add a soft, modern, approachable character. As SVG they scale sharply and recolour easily. The key to using them well is subtlety and purpose: a gentle blob or two as background accents lifts a design, while blobs everywhere in clashing colours look chaotic. They also work beautifully as masks, clipping a photo into an organic shape instead of a hard rectangle. Generating them randomly gives you variety to choose from until one sits right with your layout.
