Is this a free pattern generator?

Yes. You can browse presets, adjust controls, and export SVG, CSS, or PNG without signing in. Processing happens in your browser.

Can I make checkerboard or checkered patterns?

Yes. Open the Checkerboard family to generate checkerboard-style tiles, then adjust colors, density, and scale for checkered backgrounds or textures.

Does it include hex grid or hexagon patterns?

Yes. The Hex grid family creates honeycomb-style hex pattern tiles. Tune density, stroke, and palette colors for hex grid backgrounds.

Can I export SVG patterns for the web?

Yes. Copy SVG markup, download an SVG file, or copy a CSS background snippet with repeat settings for website backgrounds.

Is this a seamless pattern maker?

Yes. Each preset renders a tile designed to repeat seamlessly. Preview the repeat live before you export SVG or PNG.

Can I use it like a random pattern generator?

You can browse 150 presets and filter by family when you want fresh pattern ideas. Pick a tile, then customize colors and spacing.

Does it make stripe or wave SVG patterns?

Yes. Use the Lines family for stripe-style repeats and the Waves family for flowing wave SVG paths. Both export as tileable assets.

Can I download PNG versions?

Yes. Export PNG at 1x, 2x, 3x, or 4x scale when your workflow needs a raster tile instead of SVG.

Online pattern generator for seamless SVG backgrounds

Free online pattern generator for checkerboard, hex grid, stripe, and wave SVG tiles. Adjust colors live, then export seamless SVG, CSS, or PNG.

What is this pattern generator?

Pattern Monster is a hosted pattern maker and SVG pattern generator. Browse 150 tileable presets—including checkerboard, hex, line, and wave styles—tune density and colors in the browser, then copy CSS or download vector SVG and PNG for web backgrounds.

Pattern maker features

Controls and exports for tileable web and brand backgrounds.

Checkerboard and checkered presets
Start from checkerboard-style tiles for checkered layouts, textures, and alternating square rhythms without drawing a grid by hand.
Hex grid and hexagon patterns
Generate hex pattern tiles for honeycomb backgrounds, maps, and technical UI surfaces with adjustable density and stroke.
Stripe, wave, and grid SVG patterns
Line presets cover stripe-style repeats; wave presets export flowing SVG paths; grid presets build mesh-like website backgrounds.
150 presets to explore quickly
Filter by family or search palettes when you want random pattern ideas without starting from a blank canvas.
Live tile preview
See the seamless repeat update as you change tile size, scale, angle, opacity, and colors.
SVG, CSS, and PNG export
Copy SVG markup or a CSS background snippet, download tileable SVG, or export PNG at 1x–4x scale for slides and social assets.

How to create a seamless pattern online

Use the pattern creator workflow in three steps.

Pick a style family
Choose checker, hex, lines, waves, or another family, then select a palette preset that matches your layout.
Tune tile settings
Adjust density, stroke, colors, and tile size until the repeat looks right behind your content.
Export SVG or PNG
Copy CSS for a quick background, download SVG for vector workflows, or export PNG when you need a raster file.

Tips for SVG pattern backgrounds

Get cleaner checkerboard, hex, and stripe output.

01
Match tile size to your section width
A smaller tile can feel busy on full-width heroes; test the repeat at the width you will ship.
02
Use SVG for responsive UI
Vector pattern SVG stays sharp on retina screens and keeps page weight lower than large PNG tiles.
03
Lower contrast behind text
Checkerboard and hex patterns read best as subtle texture when foreground and background colors stay close.
04
Copy CSS for quick prototypes
Paste the generated background snippet into a layout shell before committing to a downloaded asset.

Great for

Common pattern generator use cases.

Website background patterns
Build repeating hero, section, and card backgrounds without opening a separate design app.
Web pattern maker workflows
Generate tileable assets for landing pages, dashboards, and marketing sites directly in the browser.
Checkerboard and hex textures
Quick checkered or honeycomb looks for games, sports themes, and technical product UI.
SVG handoff to dev and design
Share pattern SVG output with frontend teams or import tiles into Figma and slide decks.
Exploring random pattern directions
Browse presets when you need fast starting points for dots, rings, triangles, and glyph repeats.

Why use this seamless pattern maker

Technical details

How the pattern generator works under the hood.

Pattern families: Ten renderer families: dots, lines, grid, waves, glyphs, hex, zigzag, rings, checker, and triangles across fifteen color palettes.
Preview model: The current SVG tile is applied as a repeated CSS background in the live preview panel.
Outputs: SVG string export, CSS background snippet, and PNG rasterization via canvas.
Controls: Tile size, density, scale, angle, opacity, stroke width, and three-color palettes per preset.
Execution: Client-side React rendering only; no server upload or account is required.
