CSS Output
Generate Organic CSS Blob Shapes
Create irregular blob shapes by randomizing border-radius values, then copy the CSS for landing page backgrounds, profile frames, illustrations, badges, and decorative sections.
Control Shape Complexity
More randomization creates playful organic shapes, while lower complexity keeps the blob softer and easier to place behind text or cards.
About This Tool
CSS Blob Generator creates organic fluid blob shapes as SVG or CSS clip-path values for use in web design. Blob shapes are used as decorative backgrounds, image masks, and section dividers that break away from rectangular layouts.
When to Use It
Use this when designing a landing page that needs soft organic shapes, when creating an image mask for a profile photo, or when generating background shapes for a hero area.
How to Use
- Adjust the complexity and randomness sliders.
- Click Randomise to generate a new shape.
- Choose between SVG output or CSS clip-path.
- Copy the code and paste it into your stylesheet or HTML.
Frequently Asked Questions
Can I animate a CSS blob shape?
Yes. CSS animations can morph between two clip-path values to create a flowing blob animation. Define two keyframes with different blob shapes.
What is the difference between SVG and clip-path output?
SVG output creates a standalone shape element. Clip-path applies the blob shape as a mask to any HTML element such as an image or div.
Are blob shapes accessible?
Blob shapes are decorative. Add aria-hidden='true' to purely decorative SVG blobs so screen readers skip them.
