How to Use the Poster Slicer

Upload your image. Drop it in or click to browse. This is the photo that's getting turned into your poster.
Set the number of columns. That's how many tiles go across. The tool figures out the rows automatically based on your paper size, so everything lines up correctly.
Pick your paper size. Letter or A4 for standard home printers. Go bigger if you have access to a wide-format printer.
Adjust the overlap. This is the strip of shared image on each tile edge — it's what lets you line things up when you tape them together. The default of 20px works well for most people. Go higher if you want more room to work with.
Check the preview. The numbered grid shows exactly how the poster will be split.
Download as ZIP or PDF. The ZIP includes each tile as a PNG plus a color-coded assembly map and a layout guide. The PDF puts one tile per page, ready to send to your printer.
