What is SVG Shape & Wave Generator?

SVG Wave Generator creates smooth, organic waves and blobs from a handful of sliders, then hands you clean, raw SVG you can drop straight into a page. Switch between Wave and Blob modes, tune the shape and colors, and copy or download the markup. Everything renders live in your browser, and the preview is the exact SVG string you export, so what you see is what you ship.

How to use SVG Shape & Wave Generator

Choose wave or blob
Use the toggle at the top of the Controls panel to pick Wave for layered section dividers or Blob for a rounded organic shape.
Shape it with the sliders
For waves, adjust complexity (number of points), variance, height, layers, and opacity. For blobs, set the number of points and variance. More variance means a more irregular, hand-drawn feel.
Pick your colors
Choose a fill color with the swatch, flip a wave vertically, or enable a gradient fill for blobs and set both start and end colors.
Randomize until it clicks
Click Randomize to roll a new seed and instantly regenerate the shape while keeping your slider settings. The current seed is shown so you can reproduce a result.
Copy or download the SVG
Reveal the SVG code panel to copy the markup, or click Download to save a wave.svg or blob.svg file. The exported SVG is exactly what the preview shows.
