SVG Wave and Blob Generator — Free Design Backgrounds
Create fluid SVG waves and organic blob shapes for your website backgrounds in seconds with this free online SVG generator. Adjust curves, randomness, and colors visually, then copy production-ready SVG code — no design software, no plugins, and no watermarks.
SVG shapes are the modern way to add visual interest to hero sections, section dividers, and landing pages: they are infinitely scalable, weigh a fraction of a PNG, and can be styled or animated with CSS. Regenerate until you find a shape you love, then drop the markup straight into your HTML or export it as a file.
How to Generate an SVG Wave or Blob
-
Pick a shape type
Choose between smooth wave graphs for section dividers or organic blobs for decorative backdrops.
-
Tune the parameters
Adjust complexity, randomness, and height, and pick colors that match your brand palette.
-
Regenerate until it clicks
Every click produces a new random variation — iterate until the shape feels right.
-
Copy the SVG code
Copy the compact SVG markup and paste it directly into your HTML, JSX, or CSS.
Why Use This SVG Shape Generator?

Waves and blobs in one tool
Hero dividers, footers, and abstract background shapes without opening Illustrator or Figma.
-
Copy-ready markup
Clean, minimal SVG code that drops straight into any framework — React, Vue, Astro, or plain HTML.
-
Infinite variations
Randomized generation means you will never ship the same blob as another site.
-
Tiny file sizes
Vector shapes are a few hundred bytes — far lighter than raster background images.

No accounts, no export limits, no watermarks.
Frequently Asked Questions
How do I add an SVG wave divider between sections?
Generate a wave here, copy the SVG code, and place it between your sections (or as an absolutely positioned element at the bottom of one). Set its fill to match the next section's background color for a seamless transition.
Are SVG backgrounds better than PNG images?
For geometric shapes like waves and blobs, yes — SVGs scale perfectly at any resolution, weigh dramatically less, load faster, and can be recolored or animated with CSS.
Can I animate the generated blobs?
Yes. The generated paths are standard SVG, so you can animate them with CSS transforms, or morph between blob shapes using animation libraries for a fluid organic effect.
Is the generated SVG free for commercial use?
Yes — shapes you generate are yours to use in personal and commercial projects without attribution.
