SVG Blob Generator

Generate smooth, random organic "blob" shapes as clean SVG. Tune the complexity and contrast, fill with a solid color or a gradient, hit regenerate until you love it, then copy the SVG, the path data, or download the file.

Organic Blob Shapes in SVG: Why and How

Soft, irregular "blob" shapes have become a signature of modern web design β€” framing avatars, anchoring hero sections, and adding playful background depth. Because they're built as SVG paths, blobs stay razor-sharp at any size, weigh just a few hundred bytes, and can be recolored or animated with CSS.

How a Blob Is Built

This generator places a ring of points around a center, then randomly pushes each point in or out. The "contrast" control sets how far they can move β€” low values give a gently wobbly circle, high values give dramatic, lumpy shapes. The points are then connected with smooth cubic BΓ©zier curves (a Catmull-Rom spline) so the outline flows continuously with no sharp corners. The "complexity" control is simply how many points there are: fewer points make calmer shapes, more points make busier ones.

Ways to Use Your Blob

Solid Fill or Gradient?

A solid fill keeps the blob crisp and lightweight β€” perfect for flat, minimal designs. A gradient adds dimension and energy, great for hero backgrounds and landing pages. This tool writes the gradient definition straight into the SVG so the file is fully self-contained with no external dependencies.

Tips for Clean Results

Keep complexity between 4 and 8 for natural-looking blobs; higher counts can look spiky. If you'll animate between two blobs, generate both with the same complexity so the paths have matching point counts and interpolate smoothly. And remember an SVG blob is just text β€” you can paste it inline, reference it as a background image, or save it as a .svg file.

Frequently Asked Questions

It's a smooth, random organic shape drawn as an SVG path. Blobs are popular for backgrounds, image masks, and decorative accents because they're resolution-independent, tiny in file size, and easy to recolor or animate.
Copy the full SVG and paste it inline in your HTML, save it as a .svg file, or use it as a CSS background. You can also copy just the path data to use the blob as an SVG clipPath for masking images.
Complexity is the number of points around the blob β€” more points means a busier shape. Contrast is how far those points can move from a circle β€” higher contrast gives more dramatic, lumpy blobs.
Yes. Generate two blobs with the same complexity so their paths have the same number of points, then animate the d attribute between them for a smooth morphing, "liquid" effect.
Yes β€” each "Regenerate" produces a fresh random shape based on your complexity and contrast settings. Everything is generated locally in your browser; nothing is uploaded.
