Free SVG Blob Generator — Organic Blob Shapes

Generate random organic blob shapes as SVG with the UtilixVerse blob maker. Blobs are smooth, irregular organic shapes that add personality to hero sections, avatars, badges, andbackground decorations. Because the output is vector SVG, it scales to any resolution without losing quality and weighs only a few hundred bytes.

Fully controllable, fully reproducible

Tune the number of points for simpler or more complex silhouettes, raise thejitter slider for wilder organic forms, and choose a solid or gradient fill. The seed system makes every shape reproducible — type the same seed and you get the same blob, which is handy for design systems and testing.

  • • Blur the blob with CSS (filter: blur(40px)) for a soft color glow behind content.
  • • Combine multiple blobs over a mesh gradient for a rich, layered background.
  • • Add a wave divider under a blob-covered hero for a complete section design.
  • • Use the SVG Optimizer to shave bytes from your final SVG markup.

Free, offline, and private — every blob is generated locally in your browser. ExploreSVG Wave Generator andBorder Radius Generator for more organic design elements.

SVG Blob Generator FAQ

Common questions about generating blob shapes as SVG.

How do I generate an SVG blob shape?

Use the 🎲 New Shape button for a random organic blob, or type any word into the Seed field — each seed always produces the same shape, so you can share and reproduce designs reliably. Then adjust complexity (points), jitter (how organic it looks), opacity, and colors. Copy the SVG or download it as a .svg file.

Why use blobs instead of plain circles or rectangles?

Organic blob shapes feel friendly, modern, and add visual rhythm to a page. They are widely used behind avatars, in hero sections, on pricing cards, and as soft backgrounds. Because they are vector SVG, blobs stay crisp at any screen size and can be styled with CSS filters such as blur for a soft glow.

Can I use the blob SVG in Figma, Photoshop, or other design tools?

Yes. Download the .svg file or copy the code and paste it directly into Figma, Illustrator, Inkscape, or any vector editor. The SVG is standalone — it includes its own xmlns, gradient definitions, and viewBox, so it renders correctly everywhere.

Is the seed feature truly deterministic?

Yes. The generator uses a seeded random algorithm (mulberry32), so the same seed, complexity, and jitter values always produce the identical blob. This is perfect for A/B testing, maintaining brand consistency, or regenerating a shape you liked in a previous session.
