SVG Blob Generator – Free Organic Shape Creator
Generate beautiful random blob shapes for backgrounds, illustrations and UI design. Control complexity, smoothness and colors — then download as SVG or copy CSS.
What Is the SVG Blob Generator?
The SVG Blob Generator creates smooth, organic blob shapes as scalable SVG files — perfect for website backgrounds, hero section illustrations, profile image frames, and decorative elements. Adjust complexity and smoothness, apply colour gradients, and download a clean SVG or PNG file ready to drop into your design or code.
Every click generates a unique blob — click Randomise to explore hundreds of organic shapes instantly.
Downloads as a pure SVG — infinitely scalable, tiny file size, and fully editable in Figma, Illustrator, or code.
Apply solid colours or two-stop gradients to your blob to match any brand palette or design system.
Also export as a high-resolution transparent PNG for use in tools that don't support SVG.
How to Use
Adjust Complexity & Smoothness
Use the Complexity slider to control how many points define the blob shape (more = spikier), and the Smoothness slider to control how rounded the curves are.
Choose Your Colour
Pick a solid fill colour or enable gradient mode to blend two colours. Match your website's brand colours for a cohesive look.
Randomise Until Perfect
Click Randomise to generate a new random blob shape. The controls stay the same, only the random seed changes — keep clicking until you find a shape you love.
Download SVG or PNG
Click Download SVG for a vector file you can edit in Figma, Illustrator, or your code. Or Download PNG for a raster image with transparent background.
Frequently Asked Questions
Blob shapes are popular in modern web design as decorative backgrounds, hero section fills, profile picture frames (clip-path), section dividers, illustration accents, and UI card backgrounds. They add visual interest and an organic, friendly feel compared to rigid rectangles and circles.
SVG is a mathematical description of the shape — it scales to any size (from a tiny icon to a 4K display) without pixelation or quality loss. A blob SVG is typically under 1 KB versus hundreds of kilobytes for a PNG at the same visual quality. SVG also supports CSS animations and can be edited directly in code.
Use it as an <img> tag or reference it in CSS: background-image: url('blob.svg'). For inline use, paste the SVG code directly into your HTML and style it with CSS. Inline SVGs can be animated and coloured with CSS variables — useful for interactive or theme-aware designs.
Yes. All blobs generated by this tool are completely free to use in personal and commercial projects with no attribution required. The shapes are algorithmically generated, so they are not subject to any copyright or licensing restrictions.
To animate a blob morph, generate two blob shapes with the same number of points and use CSS @keyframes to transition the d attribute of the SVG path between the two states. Libraries like anime.js and GSAP make this easier with built-in SVG morphing support.
Download the SVG file, then drag it into Figma. Right-click the shape and choose "Edit Object" (or press Enter) to access the individual vector nodes. From there you can adjust control handles, change the fill, apply effects, and use it as a clip mask for images or other content.
