The Blob Generator creates smooth, organic “blob” shapes — the soft, rounded forms that are popular as backgrounds, section dividers, and decorative accents in modern web design. Adjust the complexity and contrast, pick a colour, and generate a fresh random blob with one click.
Each blob is a clean SVG path, so it scales to any size without losing quality. Copy the SVG or just the path, or download it as an SVG or PNG — all generated in your browser.
How to make a blob
- Click “New blob” to generate a random shape.
- Use Complexity to change how many points (and bumps) the blob has.
- Use Contrast to make the edges gentle or more dramatic.
- Pick a colour, then copy the SVG or path, or download SVG/PNG.
What are blob shapes used for?
- Soft background shapes behind headings, hero sections, or cards.
- Decorative accents and section dividers.
- Masks for images (clip an image to a blob shape).
- Illustrations and playful UI details.
Why SVG blobs?
Because a blob is a single vector path, the SVG is tiny and stays razor-sharp at any size — perfect for responsive designs. You can drop the SVG straight into your HTML, use the path in CSS or a component, or export a PNG when you need a raster image.
Adjusting complexity adds more control points for busier shapes, while contrast controls how far the edges push in and out from a circle.
Frequently Asked Questions
What is a blob shape?
A blob is a smooth, closed, organic shape — like a rounded splodge. It’s made from a single curved SVG path and is widely used as a soft background or decoration in web design.
Can I use these blobs commercially?
Yes. The shapes are generated by you, so you can use the SVG or PNG freely in your own projects.
How do I change the blob shape?
Click “New blob” for a fresh random shape, or adjust the complexity and contrast sliders to reshape the current one.
Is the SVG scalable?
Yes. The blob is a vector path with a viewBox, so it scales to any size without blurring.
