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.
