Blob Maker is a free SVG blob shape generator that creates random, unique organic shapes in seconds — copy SVG code or download as .svg for use in Figma, web design, and CSS animations.

What is Blob Maker?

Blob Maker by Georg Eckert is a free browser-based SVG shape generator specializing in organic, blob-like shapes. Unlike geometric shapes, blobs have irregular, flowing edges that add a natural, friendly quality to designs — perfect for backgrounds, hero sections, and image masks.

Why Use Blob Shapes in UI Design?

Blob shapes have become a key element of modern web and UI design because they:

• Break the monotony of rectangular layouts
• Add visual warmth and approachability
• Create interesting backgrounds without stock images
• Work beautifully as image masks for profile photos and cards
• Animate smoothly with CSS transitions

Key Features

• Randomize on click — Generate a new organic shape instantly with every click
• Complexity slider — Control how many curves the blob has (simple oval → complex organic form)
• SVG download — Download the generated shape as a clean .svg file
• SVG code copy — Copy the raw SVG markup to use directly in HTML or Figma
• Color picker — Choose the blob's fill color before downloading
• Free to use — No account, no watermarks, unlimited generations

How to Use Blob Maker

1. Go to blobmaker.app
2. Click Randomize to generate a shape, or drag the complexity slider
3. Pick your color using the color wheel
4. Click Download SVG to save, or copy the SVG code
5. Paste into Figma, HTML, or your CSS file

Using Blobs in CSS

You can apply blob shapes as CSS background images using inline SVG:

.hero-blob {
  background-image: url("data:image/svg+xml,...");
  background-size: cover;
}

Or combine with Fancy Border Radius for a pure CSS blob that can be animated.
