SVG Blob Generator is a free color & design tool that runs entirely in your browser — organic blob shapes with a copyable path. No upload, no account, no limits.
Generate the soft, organic blob shapes used behind headings, avatars and hero sections, and copy the path straight out. Set how many points the outline has and how far they wander, then shuffle the seed until a shape looks right — the same seed always rebuilds the same blob, so a shape you like is reproducible rather than lost on the next render.
The outline is a closed Catmull-Rom spline converted to cubic béziers, which is what keeps it smooth all the way round instead of looking like a polygon with rounded corners. Export the whole SVG, or take just the path data if you are dropping it into an existing file or a component.
Yes. The shape is derived from the seed, so noting the seed is enough to rebuild it exactly — shuffling only changes the seed for you.
Points sets how many anchors the outline has: fewer is rounder and calmer, more gives it more lobes. Wobble is how far each anchor is allowed to drift from a perfect circle, so zero is a circle and one is strongly irregular.
Take the path data and convert it to a percentage-based clip-path, or simpler, use the SVG directly as a mask — the exported file has a single path, which is what both approaches need.
Every calculation happens on this page, in your own browser. Your input is never sent to a server, never logged and never used for training — which also means the tool keeps working when you are offline.
