Craft seamless, eye-catching designs with the best free pattern generators available today. These tools let you access seamless vector patterns for all your design needs—whether you’re sprucing up backgrounds, adding text effects, or testing mockups. Patterns can take illustrations to the next level and serve as the foundation for complex graphic design projects: a subtle pattern can liven up flat website builds, while bold, attention-grabbing designs work perfectly as standalone abstract art when illustrations or stock photos just won’t cut it.
If you own Adobe Illustrator, you can create patterns using its new Adobe Firefly-powered text-to-vector tool. But if you don’t have that software, don’t worry—there’s a wide range of free online pattern generators, many of which let you save SVG files. And if you need typography to pair with your patterns, check out our roundup of the best free fonts too.
The Top Free Pattern Generators
01. Repper
Repper is primarily a paid tool (plans start at $6.99 per month for personal use), but it includes a 14-day free trial—any designer with a knack for pattern-making will want to give it a spin. What makes it stand out? It’s shockingly easy to create beautiful, seamlessly tiling patterns. Just upload a source image, tweak any of its 28 tiling settings, and you’ll quickly generate dozens of stunning abstract designs.
It also has fun effects to experiment with, and the Metamorphosis tool is a fan favorite—it lets you instantly craft MC Escher-style designs that feel both whimsical and polished.
02. Pattern Monster
Unlike Repper, Pattern Monster doesn’t let you generate patterns from your own images—but it makes up for that with a huge library of pre-made patterns you can fully customize. You’ll start with the site’s existing pattern selection, but once you find one you like, you can tweak its details: adjust the pattern itself, angle, zoom, color, and dimensions, then export it as an SVG or PNG file. Best of all? This online tool is 100% free (donations are appreciated if you want to support the creator).
03. Patternify
If you’re after a simple pattern for a website background, Patternify (created by Sacha Greif) is the solution. It’s a CSS-focused pattern generator—just paint pixels on a grid (up to 10×10 in size), and Patternify converts it into either a downloadable, tileable PNG or Base64 code you can plug right into your site’s source. The results aren’t super sophisticated, but it’s ideal if you’re building a retro-themed website and need a quick, custom background.
04. Mazeletter
For a fun twist on pattern generation, Mazeletter is a must-try. It’s less a “tool” and more a collection of nine free fonts—all designed to help you build complex, infinitely tiling maze patterns just by typing letters.
Created by Paul Cronan of Fathom Foundry, Mazeletter draws inspiration from his lifelong love of mazes. Each of the nine fonts has a unique look: you can either build patterns by hand or play around by typing letters directly on the Mazeletter site, and you’ll be amazed at how quickly you can create intricate, labyrinth-style designs.
05. Patterninja
If you want to make colorful, repeating patterns with full control over every element, Sergiy Yavorsky’s Patterninja is a standout tool. You can build patterns using ready-made icons—scale them, reposition them, or rotate them to get the exact look you want—or upload your own images to use as pattern elements.
Once you’ve nailed your perfect pattern, downloading and sharing it takes just seconds—no complicated steps required.
06. Patternizer
If stripes are your vibe, you’ll love Patternizer. It’s a simple but powerful tool focused entirely on creating stripe or crisscross plaid patterns. You can add as many layers as you want, then customize each one: set the color, rotation, opacity, width, gap, and offset to get a look that’s uniquely yours.
With a little experimentation, you can turn these basic elements into surprisingly complex patterns. When you’re done, export your design as CSS—so you can add it to any website in minutes.
07. GeoPattern
Similar to Mazeletter, GeoPattern lets you generate abstract tiling patterns by typing random text. But instead of maze-like designs, it creates vibrant SVG patterns you can save and use on your website. It uses Secure Hash Algorithms (SHA) to turn text into colors and shapes—you don’t need to understand the technical side to love the results.
The JavaScript-powered online version is a fork of Jason Long’s original GeoPattern tool. It gives you a bit more control over your designs, though it helps if you’re comfortable with basic code. You can check it out here (note: original link context preserved for accessibility).
08. Gerstnerizer
Gerstnerizer is a bit trickier to master than the other tools on this list, and it only generates black-and-white (or colorless) patterns—but it’s worth trying for its unique, chaotic designs. Based on various dot grids, it creates patterns using lines: you set the line thickness, opacity, and curvature in the controls, then choose one of three pattern shapes. From there, you can either draw lines manually or generate random ones, then save your design as an SVG.
It’s not the most intuitive tool, but for anyone looking to create bold, experimental patterns, it’s a fun option to explore.
