A free CSS pattern generator for geometric backgrounds

Pattern Generator lets you pick a geometric tile, customize foreground and background colours plus scale and opacity, then copy CSS or download SVG and PNG — in your browser, with no upload. Here is how it compares to other ways people source background patterns.

What is the fastest free way to get a CSS background pattern?

Open Pattern Generator, click a pattern, tune colours and scale, and click Copy CSS. You get a ready-to-paste background property with an inline SVG data URI that tiles on any element. Need a design asset instead? Download the SVG tile or a 1600×900 PNG from the same screen. Nothing is uploaded — the preview and exports run locally in your browser.

Pattern Generator vs. the usual options.

Designers and developers typically grab background patterns one of four ways. Each fits a different job — pick the row that matches yours.

Option Custom colours & scale Export formats Browser-local Best for
Pattern Generator Yes — foreground, background, scale, opacity Copy CSS, SVG tile, PNG (1600×900) Yes — runs in your browser Production CSS plus Figma and slide assets from one preview
Hero Patterns Limited — pick from preset patterns CSS only Yes — static pattern catalog Quick CSS snippets from a curated library
CSS-only gradient tools Yes — but gradients, not tiled geometry CSS only Yes — generators run in browser Linear and radial gradients, not repeating tiles
Figma community patterns Varies — depends on the file Figma fill / sometimes SVG download No — use inside Figma or download Mockups when you already work in Figma

Why a browser-local pattern tool helps.

Background patterns are usually chosen early in a project — before brand colours are final or before a client review. A browser-local generator lets you iterate on colour and scale without creating accounts, uploading files, or waiting on a server round-trip. Pattern Generator keeps the preview and export on your device.
