About Border Radius & Blob Generator
Elevate your web design with the Organic Blob Shape Generator, a powerful, browser-based tool crafted for modern UI/UX designers and frontend developers. Say goodbye to complex vector editing software and heavy image files. This tool allows you to effortlessly sculpt beautiful, fluid, and organic blob shapes using pure CSS, giving your websites a contemporary and dynamic aesthetic. Unlike basic shape generators, this tool offers granular, 8-point control over your design. Dedicated sliders for horizontal and vertical radii (Top Left, Top Right, Bottom Right, Bottom Left) let you fine-tune every curve to perfection. Customize the visual appeal with a built-in dual-color gradient picker, ensuring your blobs seamlessly match your brand identity or website theme. Need instant inspiration? Choose from 7 carefully curated presets (Circle, Squircle, Leaf, Drop, and more) or hit the "Random" button to discover unique, unexpected shapes. For added flair, enable the "Morph Animation" toggle to watch your shape fluidly transition between organic forms in real-time. The tool generates clean, production-ready CSS code instantly. With a single click, copy the static CSS or the advanced CSS + @keyframes animation code directly to your clipboard. Because everything runs 100% locally in your browser, your workflow remains lightning-fast, completely private, and entirely free of watermarks or usage limits. Perfect for hero sections, background accents, profile pictures, and modern landing pages.

Frequently asked questions
Is this tool free and private?
Yes, it is 100% free to use. All shape generation and code compilation happen locally in your browser, meaning no data is ever sent to external servers.
What is a "CSS Blob"?
A CSS blob is an organic, fluid shape created by applying 8 distinct values to the CSS border-radius property (4 horizontal and 4 vertical radii), breaking away from rigid, perfect circles or squares.
Can I use the generated shapes in my commercial projects?
Absolutely! The generated CSS code is yours to use freely in any personal or commercial web design project.
How do I change the size of the blob in my website?
The generated CSS includes width: 300px; and height: 300px;. You can easily change these pixel values to any size you need in your own stylesheet.
What does the "Morph Animation" feature do?
When enabled, it uses CSS @keyframes to smoothly transition the border-radius values over time, creating a living, breathing, liquid-like effect.
Are these shapes supported in all modern browsers?
Yes, the 8-value border-radius syntax (e.g., 60% 40% 30% 70% / 60% 30% 70% 40%) is widely supported across all modern browsers, including Chrome, Firefox, Safari, and Edge.
Can I export the blob as an image (PNG/SVG)?
This tool is specifically designed to generate lightweight, scalable pure CSS code. If you need an image file, you can take a screenshot of the preview or use a separate CSS-to-image converter.
Why use CSS blobs instead of SVG or PNG images?
CSS blobs load instantly, require zero HTTP requests, scale perfectly to any screen size without pixelation, and can be easily animated or modified with code, making them much more efficient for web performance.
