SVG Backgrounds: Waves, Patterns & Blobs That Keep Pages Fast

SVG vs image backgrounds

A hero image can weigh 200 KB. The same background as SVG is often 1–3 KB — and scales to any screen. For flat and geometric designs, SVG wins every time.

Waves and dividers

Layered wave dividers are a classic: generate one with the SVG background generator, tune the colors, and drop it into your hero or footer.

Seamless patterns

Patterns use a small tile with userSpaceOnUse units, so they repeat perfectly. Generate a tile with the SVG pattern generator and use it as a background-image.

Using SVG backgrounds in CSS

Convert your SVG to a data URI and use it directly in CSS:

`background-image: url("data:image/svg+xml,…");`

Performance tips

Keep shapes simple — fewer paths, smaller files

Use one shared SVG for multiple sizes
