SVG Blob Generator
Generate organic blob-shaped SVG paths for hero backgrounds, decorative dividers, or section accents. Tweak complexity (number of vertices) and randomness, lock a seed for reproducible shapes, and copy the SVG markup. Pure SVG — no JS dependency at runtime.

How to use the SVG Blob Generator
Adjust complexity (more vertices = bumpier outline), randomness (0 = perfect circle, 100 = wildly irregular), and seed (same seed always produces the same shape — useful for reproducibility). Color and size are self-explanatory.
New blob picks a new random seed and regenerates. Copy SVG gives you the raw markup; Copy CSS background gives a data-URI suitable for background-image; Download .svg saves to a file.
About SVG Blob Generator
The “blob” — an organic, roundish shape with irregular edges — has become a standard design element for hero sections, illustrations, and decorative dividers since around 2018. The shape is mathematically simple: distribute N points evenly around a circle, perturb each point’s distance from the center by a random amount, then connect them with smooth Bezier curves. The result reads as “organic” because the smoothness combined with irregular vertices avoids both perfect-circle uniformity and angular polygon-ness.
Why generate them in-browser rather than using an SVG library? Most pages need only one blob, statically positioned. Loading a JS library just to compute one path at build time is overkill. This tool generates the path once, you copy the resulting SVG into your page, and there’s zero runtime cost.
Common use cases
- Hero section backgrounds — large blob behind the headline as a color accent.
- Avatar shapes — clip-path to a blob for organic profile images.
- Section dividers — use a blob as a non-rectangular section transition.
- Decorative spots — small blobs as background accents in landing pages.
