Pattern Generator (Advanced) — SVG / CSS Patterns, Free
Generate seamless SVG / CSS patterns: dots, lines, geometric, organic. Customize colors, density. Browser-only.
About Pattern Generator Advanced
Pattern generators produce seamless tiled patterns for use as backgrounds, hero sections, dividers, and design accents. Common patterns: dots, lines, grids, hexagons, waves, chevrons, plus organic patterns like topographic / subtle noise. The ZTools Pattern Generator (Advanced) produces SVG patterns with configurable color, density, opacity, scale, and rotation — and outputs as CSS background, SVG file, or copy-pasteable data URI.
Use cases
- Hero section background. Solid color is flat. Subtle dot or line pattern adds depth without distraction.
- Email / newsletter dividers. Pattern strip between sections. Renders in most email clients.
- Print materials. Brochures, posters, business cards — patterned backgrounds at print resolution.
- App empty states. Pattern + illustration in empty states feels intentional, not bare.
How it works
- Pick pattern type. Dots, lines, grids, hexagons, chevrons, waves, plus signs, etc.
- Configure. Foreground / background color, density / spacing, opacity, scale, rotation.
- Preview. Live tile preview at multiple sizes. Toggle dark / light backgrounds.
- Export. SVG file, CSS background-image with data: URI, or PNG raster.
Examples
Input: Subtle dots, brand color #2563eb at 8% opacity
Output: Light blue dots scattered on white — adds texture without dominating.
Input: Diagonal stripes, dark mode
Output: Subtle diagonal lines in slightly-lighter shade — depth without overpowering content.
Input: Hexagon grid, large scale
Output: Tech / science-y pattern. Useful for SaaS / engineering hero sections.
Frequently asked questions
SVG vs CSS data URI?
SVG file better for caching (one HTTP request); CSS data URI eliminates the request but inlines the pattern in every page using it.
Will SVG patterns work in email?
Most modern clients yes; Outlook for Windows can be quirky. Test before campaign send.
Performance?
SVG patterns at typical complexity are negligible. Avoid overly-complex patterns (1000+ elements per tile) — they degrade scrolling.
Privacy?
All in browser.
Pro tips
- For backgrounds, keep opacity low (5-15%) — patterns should support content, not compete.
- Use SVG for vector crispness — same file scales from mobile to billboard.
- For dark mode, generate two variants (light bg / dark bg) — colors flip differently than just inverting.
- For subtle patterns, prefer 2-color (foreground + transparent) — more colors clutter quickly.
