SVG Blob Shape Generator

Generate a random, smooth, organic blob shape. Tune the number of points and irregularity, pick a color, then download a clean SVG file.

How to use the SVG blob generator

  1. Set points and irregularityMore points add detail, higher irregularity makes the outline lumpier.
  2. Randomize until you like itEvery click generates a fresh random blob with the same settings.
  3. Download the SVGGet a single-path SVG file ready to drop into any project.

How the blob shape is built

Points are placed evenly around a circle, each with a randomized radius based on the irregularity setting, then connected using smooth Catmull-Rom curves converted into cubic Bezier segments, which keeps the outline organic instead of jagged.

Point count

Fewer points make simpler, rounder blobs; more points allow finer, more detailed silhouettes.

Irregularity

Controls how far each point's radius can stray from the average, from gentle waves to spiky shapes.

Smooth curves

Catmull-Rom to Bezier conversion keeps every edge smooth and continuous, with no sharp corners.

Scalable output

The downloaded SVG uses a single vector path, so it stays crisp at any size.

SVG Blob Shape Generator FAQ

How is the blob shape generated?

Points are placed evenly around a circle with a randomized radius, then joined with smooth Catmull-Rom curves converted to cubic Beziers, producing an organic closed shape.

What does the irregularity slider do?

It controls how much each point's radius can vary from the average, so higher values create lumpier, more irregular blobs.

Can I get a different blob with the same settings?

Yes, press Randomize to generate a new random blob using your current point count, irregularity and color.

What file format does the download use?

The download is a plain SVG file with a single filled path, so it scales to any size without quality loss.

Can I use the blob as a background shape?

Yes, SVG blobs are commonly used as decorative background shapes behind images or hero sections on websites.
