Design Beautiful SVG Blobs in Seconds
Organic "blob" shapes are one of the most popular design trends in modern web design — they appear as hero backgrounds, section dividers, decorative accents on cards, and even as app iconography. This SVG Blob Generator lets you create unique, perfectly smooth blob shapes with a handful of sliders, then copy the SVG or download it for use in any project.
How the Blob Is Built
The generator places a number of anchor points evenly around a circle, then offsets each point's radius by a random amount based on the selected randomness value. The points are connected into a closed smooth curve using cubic bezier segments derived from a Catmull–Rom spline, which guarantees a clean, continuous outline with no visible corners — no matter how chaotic the underlying points are.
A deterministic seed drives every random decision, which means the same configuration always produces the exact same blob. Hit the re-roll button to cycle through new shapes without changing anything else.
Customization Options
- Complexity — number of anchor points (3 to 20). Lower values give gentle, rounded blobs. Higher values produce complex, wavy outlines.
- Randomness — how much each point can stray from the base radius. Zero yields a circle; full randomness yields dramatic organic shapes.
- Seed — integer that makes every result reproducible. Set the same seed to always get the same shape.
- Fill — pick a solid color or a two-stop linear gradient with an adjustable angle.
- Stroke — optional outline with configurable color and width.
Output Formats
The generator produces clean, minimal SVG markup you can paste directly into an HTML document, a React component, a Figma file, or any design tool that accepts SVG. You can copy the code to the clipboard with one click, or download the shape as a standalone .svg file.
Common Uses
- Hero backgrounds and landing page accents
- Avatar-style image masks
- Decorative shapes behind feature cards
- Abstract badges and sticker-style UI elements
- Blob transitions between page sections
- Presentation slide decorations
Because the output is plain SVG, it scales crisply at any resolution, has a tiny file size, and can be animated with CSS or JavaScript. You can also edit the resulting path in design tools like Illustrator, Figma, or Inkscape if you need further tweaks.
