| Mode | What it does |
|---|---|
| Straight repeat | Every tile identical, aligned in a clean grid |
| Brick offset | Alternating rows staggered by half a tile width |
| Mirror repeat | Tiles flip on alternating axes so edges blend seamlessly |
| Half-drop | Alternating columns offset vertically by half a tile height |
Mirror mode has three flip options — H+V (both axes), Horizontal only, or Vertical only — giving you control over how the edges meet.
| Preset | Dimensions | Best for |

Pattern Boon Studio grew out of a real workflow problem — creating seamless repeating patterns from original AI art images, one at a time, across multiple tools with upload limits and format restrictions.
This tool does the whole pipeline in one shot. Four repeat modes. Bulk processing. Offline. Free.
The mirror repeat mode was inspired directly by kaleidoscopic AI art — images where the edges meet and create something completely new that wasn't in the original tile.
