SVG Blob Generator

The Online SVG Blob Generator is an and easy-to-use tool for creating unique SVG blob shapes for your website or digital projects. SVG blobs are abstract, organic shapes that can be used for backgrounds, illustrations, buttons, or decorative elements, giving your designs a modern and dynamic look.

With this tool, you can customize the blob’s color, complexity, and randomness to create a shape that perfectly matches your design needs. Whether you want smooth, simple forms or more intricate, irregular shapes, the generator gives you full control over the final result.

Once you’ve created the perfect blob, you can download it as an SVG or PNG file for further editing or integration. This makes it a fast and convenient way to generate high-quality, scalable graphics without needing advanced design software.

How to use it

The svg blob generator is a great free online tool to create cool looking blobs for your website.

Choose your coloursPick Solid for one colour or Gradient for two, then use the colour boxes to choose them. Swap colours flips the direction of a gradient.
Shape the blobPoints sets how many bumps the blob has, and Randomness sets how uneven they are. Moving either slider makes a new shape.
Roll the dicePress New blob for another random shape with the same settings, or switch to Outline only for a line version.
Save itDownload as SVG or PNG, or copy the SVG code straight into your page.

Ideas for your blobs

Hero backgrounds

Place a large, soft gradient blob behind a heading to add depth without a photo.

Image masks

Use the path as a clip-path so images and avatars take on an organic shape.

Tiny and scalable

The SVG is only a few hundred bytes and stays sharp at any size, which is better than a big PNG.

Frequently asked questions

How do I use the SVG on my website?

Save the file and add it with an img tag, or paste the copied SVG code straight into your HTML. You can also use it as a CSS background by saving the file and pointing background-image at it. Our Image to Base64 Converter can embed it directly in your stylesheet.

What is the difference between Points and Randomness?

Points is how many anchor points make up the shape, so more points give more bumps. Randomness controls how far each point can wander from a perfect circle. Low values give a rounded, regular shape, and high values give a more irregular one.

SVG or PNG, which should I choose?

SVG is a vector format that stays sharp at any size and can be recoloured in code, so it is the best choice for websites. PNG is a fixed-size picture, which suits places that do not accept SVG. PNG downloads keep a transparent background.

Can I get the exact same blob again?

Each blob is generated at random, so there is no seed to recreate it. If you like one, save the SVG file or copy the code. The path in the code is the shape itself.

Can I use transparent colours?

This version uses solid colours picked with your browser’s colour picker. To make a blob see-through, add an opacity or fill-opacity attribute to the path in the downloaded SVG.

Is anything uploaded?

No. The blob is created and saved entirely inside your browser, and nothing is sent to our servers.
