Background pattern generator
Polka dots, diagonal stripes, grid, zigzag or waves: pick two colors and the density, watch the tiled preview and download a seamless PNG tile ready to repeat.
The downloaded tile repeats seamlessly with no visible joints.
What makes a pattern truly seamless
A seamless tile is an image whose edges line up perfectly: whatever exits on the right comes back in identical on the left, and the same holds vertically. This generator draws every motif with that continuity in mind — the diagonal stripes, for instance, are spaced at exact fractions of the tile — so you can repeat the PNG forever without seams or visible steps.
How to use the downloaded PNG
On a website, one line of CSS is all it takes: background-image: url(pattern.png);
background-repeat: repeat;. The same tile works as a fill in Canva, PowerPoint, Photoshop
or GIMP (via "Define Pattern"), as a background for YouTube thumbnails and social posts, or as a
subtle texture for letterheads and greeting cards. The higher the density, the smaller and
tighter the weave.
