Free SVG Blob Generator

This blob generator creates random, organic SVG blob shapes you can drop straight into a website, app or design. Adjust the complexity and spikiness sliders to go from soft, rounded blobs to sharp, irregular ones, pick a solid or gradient fill, then copy clean SVG or CSS — no accounts, no watermarks, and nothing is uploaded. Everything runs 100% in your browser, so it works offline and your shapes stay private.

How to make a blob

  1. Set the complexity (number of points) for the shape.
  2. Increase spikiness for a more irregular, random blob.
  3. Choose a solid colour or a gradient blob fill.
  4. Copy the SVG markup, or the CSS with the blob as a background image.

Frequently asked questions

What is a blob generator?

A blob generator (or "blobmaker") is a tool that produces random organic blob shapes as SVG. They're popular as decorative background shapes, avatars, hero section accents and image masks.

Is this SVG blob generator free?

Yes — it's completely free with no sign-up. You can generate and copy as many blobs as you like, and there are no watermarks.

Can I use the blobs as a CSS background?

Yes. Copy the CSS output to use the blob as a background-image, or grab the raw SVG to inline it directly in your markup.

Does my data leave my browser?

No. Every blob is generated locally in your browser — nothing is sent to a server, so it works offline and keeps your work private.
