Seamless Pattern Generator
Build tileable repeating patterns — dots, stripes, chevron, herringbone, fish scales, diamonds, Moroccan quatrefoil and waves. Every tile is drawn with wrap-around geometry, so the 3×3 preview below shows the true repeated result with no seams.

Seamless check — 3×3 repeat
Single tile (128×128px)
The lattice period divides the tile exactly, so motifs crossing an edge continue on the opposite edge by construction.

About this tool
This generator composites every pattern with a repeating canvas pattern, drawing wrap-around geometry so each tile is exactly periodic along both axes — the 3×3 grid lets you confirm the seams disappear. Patterns are rendered on an HTML canvas at full tile resolution, so the exported PNGs are pixel-accurate and ready for fabric printing, CSS background-repeat, or texture work. Everything runs entirely in your browser; no image is ever uploaded.
