Make Your Image Seamless & Tileable
Take your own artwork or photo and make it repeat perfectly — this tiles the image you upload, it does not AI-generate a new pattern, so your design stays yours. Preview the repeat live, hunt down every seam, blend the edges smooth, then export a true 300 DPI tile for fabric, wallpaper, gift wrap and print-on-demand products. Built for POD and fabric sellers.

Seamless pattern FAQ
What actually makes a pattern “seamless”?
A pattern is seamless when the right edge of the tile continues perfectly into the left edge, and the bottom into the top — so when it repeats there is no visible line, gap or jump. The classic fix is the offset method: shift the tile by half so its outer edges (which used to be hidden) meet in the middle, then blend that new center seam away. This tool does exactly that with the Edge blend slider, and lets you confirm the result with Seam check. A Mirror layout is seamless by construction, since every edge meets a flipped copy of itself.
What resolution do print-on-demand sites need?
Most fabric and wallpaper POD services (Spoonflower, Society6, Redbubble and similar) work in 300 DPI. At 300 DPI a 3600 × 3600 px file prints at 12 × 12 inches, and 4200 × 4200 px prints at 14 × 14 inches — both common repeat sizes. Export at the largest size your source image can support cleanly; upsizing a tiny tile will look soft in print.
Half-drop vs straight repeat — which should I use?
Straight repeat stacks every tile in a plain grid — great for geometric, structured motifs. Half-drop shifts every other column down by half a tile, which breaks up obvious rows and columns and hides the grid. Half-drop is the go-to for florals, organic and scattered motifs because it reads as more natural and makes the repeat much harder to spot. Half-brick does the same thing horizontally, like laid bricks.
