Spacing — Add gap between pattern elements (0-40px)
Opacity — Control transparency (5-100%)
Stroke — Adjust line thickness for stroke-based patterns (1-8px)

Export Your Pattern

Choose your preferred export method based on your needs:

Download PNG — A raster tile image ready to use as a repeating background
Download SVG — A scalable vector tile for high-quality output

Frequently Asked Questions

What does "seamless" mean?

A seamless pattern tiles perfectly in all directions without visible seams or gaps. When you repeat the pattern horizontally and vertically, the edges connect smoothly to create a continuous design. This is essential for backgrounds that need to cover large areas without showing repetition boundaries.

What is the difference between PNG and SVG export?

PNG is a raster format — the image has a fixed resolution based on the tile size you choose. It's perfect for web backgrounds and general digital use.

SVG is a vector format that can be scaled to any size without losing quality. For web backgrounds, PNG works well. For print or large-format designs where you need perfect clarity at any size, SVG is recommended.

How does the CSS export work?

The CSS export generates a background-image property with your pattern encoded as a data URI. You can paste this directly into your CSS file to use the pattern as a repeating background without needing a separate image file.

This approach reduces HTTP requests and keeps your pattern embedded in your stylesheet, making it easier to manage and deploy.

What is the tile size?

The tile size determines the dimensions of the exported image in pixels. A larger tile size includes more pattern repetitions and produces a larger file.

For most web use cases, 200x200 or 400x400 works well, providing a good balance between quality and file size. For high-resolution displays or print projects, consider using 600x600 or 800x800.

Can I use the patterns commercially?

Yes, absolutely. Patterns you create with this tool are generated entirely in your browser. You own the output and can use it for any purpose, including commercial projects, client work, products for sale, and more.

No attribution required, no licensing fees, no restrictions.

What does the Stroke slider do?

The Stroke slider controls the line thickness for patterns that use outlines instead of fills, such as Lines, Grid, Waves, Circles, Scales, and Arrows.

For filled patterns like Dots, Diamond, and Hexagon, the stroke setting has no visible effect since these patterns use solid shapes rather than outlines.
