How to Use SVG Blob Generator

Follow these steps to get the best results.

1
Set complexity and smoothness
Use the Complexity slider to control how many anchor points the blob has, and Smoothness to control how rounded the curves are between them.
2
Choose colours
Select a fill colour or enable the gradient toggle to blend two colours diagonally across the shape.
3
Randomise until you find the right shape
Click Randomise Shape to generate a new random blob with the same settings. Each click produces a unique organic form.
4
Download or copy
Click Download SVG to save the file, or Copy SVG to grab the code and paste it directly into your HTML or design tool.

Why Use This Tool?

Organic blob shapes have become one of the defining visual trends in modern web design — they add visual warmth, break rigid grid structures, and create a sense of organic naturalness that geometric shapes cannot. SVG format is ideal for these shapes because it is infinitely scalable (perfect at any resolution from favicon to full-screen background), lightweight (typically under 1KB), and can be animated with CSS or JavaScript. This generator creates mathematically smooth curves using cubic Bezier interpolation between randomly distributed anchor points.

Frequently Asked Questions — SVG Blob Generator

What is a blob shape in web design?
A blob is an organic, irregular closed shape — somewhere between a circle and an abstract splatter. They are widely used as background decorations, image masks, icon backgrounds, and section dividers in modern web and app design.
Can I use the SVG as a CSS background?
Yes. You can use it as an SVG background image in CSS, inline it directly into HTML, or reference it as an img src. For CSS background use, encode it as a data URI.
Can I animate the blob?
Yes. The SVG path can be animated using CSS animations on the d attribute (in browsers supporting it) or using JavaScript libraries like GSAP or anime.js for smooth morphing between two blob paths.
Does the SVG work in all browsers?
Yes. SVG is supported in all modern browsers. The generated SVG uses only basic path, linearGradient, and defs elements which have universal browser support.
Can I use these blobs commercially?
Yes. The shapes generated by this tool are algorithmically produced and contain no proprietary content. You may use them freely in personal and commercial projects without attribution.

About SVG Blob Generator

SVG (Scalable Vector Graphics) is an XML-based vector image format that describes two-dimensional graphics using geometric shapes, paths, and text. Unlike raster formats like PNG or JPEG, SVG images are resolution-independent — they render perfectly at any size from a tiny icon to a full-screen display. Blob shapes are closed SVG paths where control points are positioned using cubic Bezier curves that interpolate between irregularly spaced anchor points on a perturbed circle. The result is an organic, asymmetric shape that avoids the rigid regularity of circles and rectangles while maintaining a smooth, natural appearance.
