SVG Blob Generator

Shuffle organic blobs, fill with colour, gradient or photo, and export as SVG, PNG, path or clip-path. Every shape is seeded, so you can always get it back.

Other shapes from this seed

Eight more shapes at the same edge count and growth — press one to take it.

Shape

More edges is more detail; higher growth pulls the low points back out towards the circle, so 9 is nearly round and 1 is a splash.

The seed and the three numbers above are the whole shape. Note them down — or read them off the filename — and this blob comes back exactly.

Backdrop

Transparent is what you want for a background shape — the page behind it shows through in both the SVG and the PNG.

Size

The SVG scales to anything regardless — this is the box its coordinates are written in, and the size of the PNG.

The path is the d attribute on its own; the CSS is a clip-path rule that cuts an element to this shape.

How it works

How to make an SVG blob?

  1. Set the shape

    Pick a preset or use the sliders. Edges control outline points; growth controls roundness.

  2. Shuffle until one is right

    Hit shuffle for a new blob at the same settings. Eight alternatives sit under the preview.

  3. Colour it

    Fill with a solid colour, gradient, radial, or your own photo. Add outline or shadow if needed.

  4. Take it away

    Download SVG or PNG, or copy the SVG, path, or CSS clip-path into your code.

Spec sheet

Features worth using

Shapes you can get back

Every blob has a seed on screen and in the filename. Enter it anytime to recreate the exact shape.

Edges, growth and rotation

3–20 outline points, nine steps of roundness, and rotation that turns a shape without replacing it.

Solid, gradient or radial

Flat fill, linear or radial gradients, ready-made palettes, and a random colour pair button.

A photo inside the blob

Crop any picture to the shape. The image is embedded in the SVG, so it works offline.

Four ways out

Download SVG or PNG, or copy the markup, path data, or CSS clip-path — same shape every time.

Nothing is uploaded

Everything runs in your browser. No uploads, no account, no watermark.

The two sliders

What edges and growth actually do?

A blob is a circle whose radius wanders. Edges is how many times it is allowed to wander — the number of points the outline curves through. Growth is how close the nearest point may come to the centre, so it sets how deep the valleys go. Every shape below is drawn by the same code as the tool above.

Low growth cuts deep valleys and reads as a splash. High growth barely leaves the circle.

Three edges is a rounded triangle. Past a dozen the bumps get small enough to read as texture rather than form.

Where they go

What to use an SVG blob for?

UseHow
Hero and section backgroundsA large, low-contrast blob behind a headline breaks up a flat page without the weight of a photo. Keep the backdrop transparent so the page colour shows through.
Avatar and image masksFill with a photo instead of a colour. The picture is cropped to the shape and centred, so a square portrait comes out organic rather than boxed.
CSS clip pathsCopy the clip-path rule and drop it on a div, an image or a video of the same size. The element is cut to the blob, and everything inside it stays live.
Slides, posts and thumbnailsA PNG with a transparent background drops straight into a deck, a story or a canvas app as a shape you can move around.
Logos and stickersTurn the outline on and the fill off for a drawn line, or stack two blobs at different seeds for a lockup with depth.

Questions

Frequently asked questions

Is this SVG blob generator free, and can I use the shapes commercially?

Yes — free, no account, no watermark. Use the shapes anywhere, including commercial work, with no attribution.

What is an SVG blob used for?

Background shapes, section dividers, photo masks, and decorative colour fields. As vectors they stay sharp at any size.

Does anything get uploaded?

No. Generation and export stay in your browser. Photos are embedded locally and never sent to a server.

Can I get the same blob back later?

Yes. Each shape has a seed (shown on screen and in the filename). With the same seed, edges, growth and rotation, it comes back exactly.

Can I export a PNG with a transparent background?

Yes. Keep the backdrop transparent for a PNG with alpha, up to 2000 px. Set a backdrop colour if you want it flattened.
