SVG Blob Generator
Generate a random organic blob shape, tweak its randomness and point count, then copy or download the SVG.
How it works
Points are spaced evenly around a circle, then each one's distance from center is nudged by a pseudo-random amount scaled by the randomness slider. The seed feeds a small deterministic pseudo-random number generator, so the same seed, point count, and randomness always reproduce the exact same shape, useful for saving or sharing one you like. Those points are then connected with a smooth Catmull-Rom-style curve converted to SVG cubic bezier segments, which is what keeps the outline organic instead of faceted.
Everything is generated and rendered directly as SVG in this page. Nothing is uploaded.
Common questions
How is the blob shape built?
A set of points is placed evenly around a circle, each nudged inward or outward by a random amount controlled by the "randomness" slider, then connected with a smooth closed curve through all of them. More points means a more detailed, less rounded outline.
Can I get the same blob again later?
Each blob has a seed number shown next to the regenerate button. Type that seed back in (or share it) to reproduce the exact same shape, since the random nudges are derived from it deterministically.
Is this sent anywhere?
No, the shape is generated and rendered entirely in your browser. Nothing is uploaded.
