Poster Tiler: Print a Large Picture Across Several Sheets
Make a large poster from a picture with an ordinary printer: choose the poster width, the paper, margins, and overlap, see how many sheets it takes and the print resolution, and download a PDF with one tile per page, labelled and with corner marks for trimming and gluing.
Poster Tiler: Print a Large Picture Across Several Sheets: The poster is divided into a grid of sheets, each printing the area inside its margins, with neighbouring tiles sharing the overlap so they can be glued. A 3000 × 2000 px picture 600 mm wide is 600 × 400 mm, which takes eight A4 sheets, four across and two down, with 10 mm margins and overlap, printed at 127 dpi.

Nothing is uploaded
Print the PDF at 100% (actual size), trim one edge of each sheet along the corner marks, and glue it over its neighbour's overlap, working row by row: A1, A2, and so on. The picture never leaves your browser.
Planning
The tool picks the orientation that needs the fewest sheets unless you choose one; landscape suits wide pictures and portrait tall ones, but not always.

Frequently asked questions
How big a picture do I need?
For a sharp poster up close, aim for at least 100 to 150 dpi at the final size; seen from a distance, less is fine. The tool shows the resolution as you change the width.
Why print at 100%?
Fit to page shrinks each sheet slightly, so the tiles would no longer line up; choose Actual size in the print dialog.
Which edges do I cut?
Trim the top or left margin of each sheet along the corner marks and glue it over the overlap of the sheet before it, row by row.
