SVG Blob Generator Online

Updated 2026-10-24

Generate organic SVG blob shapes online for free. Drag the complexity and randomness sliders, pick a colour, and randomize until you find a shape you like, then copy or download the SVG. Everything runs in your browser, so nothing you create is uploaded.

Those soft, irregular blob shapes are everywhere in modern web design, but drawing a smooth organic outline by hand is fiddly. This generator places points around a circle at random distances and joins them with a smooth spline, so every click gives you a clean, scalable blob, ready to drop in as a background shape, an image mask, or a decorative accent.

// how to use

1 Drag the complexity and randomness sliders to shape the blob and pick a fill colour.
2 Click Randomize until you get a shape you like.
3 Copy the SVG or download it to drop into your design or code.

// examples

complexity 10, randomness 80%

Output

A more irregular blob with more points and stronger wobble.

// faq

Is anything uploaded to a server?

No. The blob is generated entirely in your browser, so nothing you create leaves your machine.

How is the blob shape made?

Points are placed around a circle at slightly random distances, then joined with a smooth Catmull-Rom spline so the outline flows naturally. More points and more randomness give a more irregular shape.

What do complexity and randomness control?

Complexity sets how many points form the outline, so higher values allow more lobes. Randomness sets how far each point strays from a perfect circle, so higher values make the blob more organic and uneven.

Can I recolour or resize it later?

Yes. The SVG uses a single fill attribute you can change in code or a design tool, and because it is vector it scales to any size without losing quality.

Where can I use the SVG?

Paste it inline in HTML, use it as a background shape, an avatar mask, or a decorative section divider, or import it into design tools that accept SVG.
