SVG Pattern Generator — Seamless Background Patterns for CSS

Give sections and cards a subtle texture with seamless SVG patterns: dots, grids, diagonal lines, zigzags, waves, plus signs, checkerboards, circles, triangles and more. Adjust the tile size, stroke, colors and opacity, then copy a tiny CSS background with the SVG inlined — no image file — or download the tile.

How to use the SVG Pattern Generator

  1. Pick a pattern — dots, grid, lines, zigzag, waves, plus, checkerboard, circles, triangles, cross-hatch, diamonds or stripes.
  2. Set the tile size, line thickness and opacity; low opacity makes subtle textures.
  3. Choose the pattern and background colors, or a transparent background to lay it over your own color or gradient.
  4. Copy the CSS (the SVG is inlined as a data URI) or download the tile as an SVG file.

Why SVG patterns?

A pattern tile is a tiny SVG — usually under 300 bytes — that the browser repeats with background-repeat. It stays sharp at any zoom level and on retina screens, needs no extra request when inlined as a data URI, and recolors instantly by changing two values.

.hero {
  background-color: #0f172a;
  background-image: url("data:image/svg+xml,…");
  background-size: 24px 24px;
}

Patterns are built so their edges line up perfectly when tiled. To layer a pattern over a gradient, tick Transparent background and list both images: background-image: url(…pattern…), linear-gradient(…). For hero dividers, see the SVG Wave Generator and Section Divider Generator.

Frequently asked questions

How do I add a dot pattern background in CSS?
Choose Dots, set the size and colors, and copy the CSS: it sets background-image to an inline SVG tile and background-size to the tile size, so the dots repeat seamlessly.
Can I use the pattern on top of a gradient?
Yes — tick Transparent background, then add your gradient after the pattern: background-image: url(...), linear-gradient(...).
Do SVG patterns slow a page down?
No. Each tile is a few hundred bytes inlined in the CSS, so there is no extra download, and SVG renders efficiently.
Can I use the pattern in Webflow?
Yes — paste the CSS into an Embed with a style tag targeting your class, or download the SVG tile and set it as a background image with tiling.
Can I install SVG Pattern Generator as a web app and use it offline?
Yes. SVG Pattern Generator is an installable web app (PWA) — installed from your browser, not downloaded from an app store. Click Install app at the top of this page in Chrome or Edge (Windows, macOS, Linux, ChromeOS) or on Android, use Share → Add to Home Screen on iPhone and iPad, or File → Add to Dock in Safari 17+ on a Mac. It then opens in its own window with its own icon, and because it runs entirely in your browser it keeps working offline. Firefox on desktop can’t install web apps. How installing works.
