SVG Blob Generator
Create random, organic, and unique SVG shapes for your next design project.
About the SVG Blob Generator
The SVG Blob Generator is a specialized tool for web designers and developers who want to add organic, flowing shapes to their projects. In modern web design, "blobs" have become a popular alternative to standard boxes and straight lines. They add a friendly, approachable, and dynamic feel to user interfaces, often used as background elements behind product shots, hero headers, or testimonials.
Creating these organic shapes manually in vector software like Illustrator can be time-consuming. This tool automates the process using mathematics. It generates unique shapes by randomizing points around a circle and connecting them with smooth curves (splines). This means every click of the "Generate New Blob" button creates a completely unique shape that you can claim as your own.
You have full control over the aesthetic. Adjust the "Complexity" to add more curves, or tweak the "Randomness" to make the shape wilder or more uniform. Once you are happy, you can copy the raw SVG code to paste directly into your HTML, or download the file to use in your design tools like Figma or Sketch.
How to Use the Tool
- Click the "Generate New Blob" button to instantly create a random shape.
- Use the "Points" slider to control how complex or simple the shape is (fewer points = smoother, rounder blob).
- Use the "Randomness" slider to control how much the shape deviates from a perfect circle.
- Customize the "Fill Color" and "Opacity" to match your brand or website theme.
- Add a "Stroke" (outline) if you want a line-art style blob.
- Copy the code from the text box or click "Download SVG" to save the file.
Frequently Asked Questions
How do I use these blobs in CSS?
The easiest way is to download the SVG and set it as a background image: background-image: url('blob.svg');. Alternatively, if you copy the code, you can Data-URI encode it or paste the SVG tag directly into your HTML for full control over styling via CSS.
Can I use these blobs for masking images?
Yes! SVG blobs are perfect for clipping masks. In your HTML/SVG code, you can wrap the blob path in a <clipPath> tag and apply it to an <image>. This creates the popular effect where a photo appears inside an organic liquid shape.
Are these shapes copyright free?
Yes. The shapes are generated mathematically by your browser in real-time. You have full rights to use any shape generated by this tool in your personal or commercial projects without attribution.
Why does the code use a `viewBox`?
The `viewBox` attribute allows the SVG to be responsive. It defines the coordinate system of the shape. By keeping the viewBox square (500x500), the blob will scale perfectly to fit whatever container you place it in on your website.
