Seamless Pattern Maker App for PNG & JPG, Repeat Pattern and Digital Paper Tool

Create seamless repeat patterns, digital papers, fabric designs, sublimation backgrounds and more from your own PNG and JPG artwork with Pattern Loom.

Pattern Loom is an easy-to-use browser-based seamless pattern maker that lets you arrange your own design elements and instantly see how they repeat—without a subscription, account or complicated design software.

Upload individual design elements, arrange them on the tile, and Pattern Loom automatically continues edge artwork on the opposite side. Preview the full 3×3 repeat, then download a finished PNG in the size and background you choose.
