Free SVG background generator, animated by default.
Vayro is a browser based SVG background generator with four engines: Wave, Blob, Mesh Gradient and Shape Scatter. Every engine animates. Shape it with live controls, then export plain SVG + CSS that drops into any site. Free, no account, nothing you make leaves your browser.

What makes it different from other SVG background generators
Most SVG background generators stop at a static shape. You get a wave or a blob as a file and the motion is your problem. Vayro is motion first: every engine has animation built in, and the export carries it. Wave, Blob and Shape Scatter export CSS keyframes; Mesh Gradient uses native SVG animate for the drift, because CSS cannot animate those attributes portably.
The export is built around one rule: the SVG class names always match the CSS selectors. Paste the SVG, paste the CSS, it animates. No renaming, no bundler, no JavaScript runtime. Switch to static mode and you get the same composition without motion.
Everything is seeded and deterministic. The same seed always produces the same background, so a share link reproduces a composition exactly, and you can come back a month later and get the same file.
Four engines, one export contract
Wave stacks layered, flowing shapes for hero sections and dividers. Blob scatters soft organic forms across the canvas with slow drift. Mesh Gradient blends blurred colour points into aurora and vignette effects. Shape Scatter distributes geometric shapes with float, pulse or drift motion. Each has its own presets, colour palettes and canvas sizes from HD to 4K, square and portrait included.
All four export the same way: Copy SVG, Copy CSS, Download SVG, Download PNG, or copy a share link. Every animated export includes a prefers-reduced-motion guard so users who opt out see a stable static frame.
Three steps to a live background
- Step 1Pick an engine
Wave, Blob, Mesh Gradient or Shape Scatter. Start from a preset or a blank canvas.
- Step 2Shape it live
Colours, layers, complexity, speed, blur, canvas size. Every slider updates the preview instantly.
- Step 3Copy and paste
Copy the SVG and the CSS. Class names match, so it animates the moment it lands in your page.
Common questions
Is the SVG background generator free?
Yes. The whole generator is free to use today, with no account, no credit card and no watermark. Exports are yours to use in client work and products.
Does it generate animated SVG backgrounds or only static ones?
Both. Every engine animates by default and exports the animation as CSS keyframes or SVG animate. Switch to static mode to export the same composition without motion.
Do I need JavaScript to use the exported background?
No. The output is a plain SVG file plus a CSS block. There is no runtime library and no build step. It works on static sites, WordPress, Webflow, React, anywhere a browser renders SVG.
What sizes can I export?
Presets from 1280x720 up to 3840x2160, plus 1200x630 for social cards, 1080x1080 square and 1080x1920 portrait, or any custom size in between.
Is my design sent to a server?
No. Vayro runs entirely in your browser. Share links encode the design in the URL itself, so nothing is stored on our side.
