Why Use This Tool?

How are these patterns built without images?

Every pattern here is generated with pure CSS gradient functions — radial-gradient() for dots, repeating-linear-gradient() for stripes and diagonal lines, and layered linear gradients combined via background-size and background-position for the checkerboard and grid-line effects. Because it's CSS rather than an image file, the pattern is infinitely scalable, loads instantly, and can be recolored just by editing two color values.

Will the pattern tile seamlessly?

Yes. Each pattern type uses a repeat unit sized exactly to your chosen spacing value, so background tiles line up edge to edge with no visible seams, no matter how large the element is that you apply it to.

Where can I use these patterns?

These lightweight CSS patterns work great as subtle section backgrounds, card textures, email backgrounds, or decorative dividers on any website — they add visual texture without the file-size or loading cost of a background image.

Is this free for commercial use?

Yes, every pattern generated here is free to use in personal and commercial projects, with no attribution required. The tool runs 100% client-side in your browser, and none of your design choices are ever uploaded or stored.
