SVG Blob Generator

Create a soft abstract SVG shape you can reproduce, preview, copy, or download without uploading anything.

The same seed and settings reproduce the same blob.

Adds bounded radius variation around the regular shape.

A QUICK WALKTHROUGH

How to use this tool

  1. Choose a seed, 3–12 points, regularity, irregularity, size, fill, and opacity.
  2. Preview the smooth closed blob and change the seed when you want another repeatable shape.
  3. Copy the SVG or path, download the SVG, or reset the controls.

Deterministic abstract geometry

The seed feeds a small local pseudo-random generator, so identical settings produce identical points and path data. The blob is an abstract decorative shape; it does not trace a real object, photo, or geographic boundary and does not call a remote service.

Bounded smooth output

Choose 3–12 points, 0–100% regularity, 0–50% irregularity, and a 64–640px square canvas. The output uses one closed path made from quadratic curves, a solid fill, and opacity from 0–100%. Smoothing keeps the path inside the canvas with a practical margin, while higher irregularity changes each point’s radius without making an uncontrolled polygon.

GOOD TO KNOW

Common questions

Will the same seed always match?

Yes. The same seed and control values use the same local deterministic sequence and produce the same SVG path in this version.

Is this a logo or illustration tracer?

No. It creates abstract decorative blobs from generated points. Use a vector editor or illustration workflow for a specific mark or traced shape.

Does the SVG load anything remotely?

No. Preview, path generation, copy, and download happen entirely in the browser.
