How it works
Four steps from full battle map to printable room sheets.
Step 1
Upload your map
Drop a PNG, JPG, or WebP battle map. Everything stays in your browser.
Step 2
Calibrate the grid
Auto-detect the grid or mark a square so each game square prints at one inch.
Step 3
Draw room polygons
Outline each room on the map. Snap to grid, rename, and refine corners.
Step 4
Print letter sheets
Preview US Letter layouts and download a PDF ready for fog-of-war play.
