Blob Generator — free online shape maker
You want to drop a soft, rounded shape behind your text or under a logo, but drawing one by hand never looks quite right. The corners come out stiff, the curves go lumpy. We added a free tool that does it for you — Blob Generator — right in your browser.
What it does
It creates unique, smooth organic shapes you can use as backgrounds, behind logos, or in illustrations. You move a few sliders to change how the blob looks, pick the color you want, and then save it as an SVG or a PNG. Every shape comes out clean and rounded, no drawing skills needed.
Nothing leaves your device
Everything happens right in your browser. Your shapes are made on your own computer, nothing is uploaded to a server, and nothing is saved anywhere after you close the page.
How to use it
- Open Blob Generator and move the sliders until the blob looks the way you like.
- Pick a color for the shape.
- Export it as SVG or PNG and drop it into your design.
It's free with no limit. There are more small tools on the Apps page.
