Cleaner joins
Add overlap, crop marks, and page labels so the sheets are easier to trim and assemble.

The original image and generated PDF stay in your browser.
Print one image across several sheets
Choose a page grid when you know how many sheets you want. Use exact width when the finished poster must match a measurement. The tool preserves the image proportions and shows the resulting page count before export.
FAQ
How do I print a large image on multiple pages?
Upload the image, choose the paper and poster size, create the PDF, then print every page at Actual Size or 100%.
Why should poster pages overlap?
Most home printers leave an unprinted edge. A small overlap repeats part of the image so you can trim one sheet and align it over the next without a white gap.
Which resolution is good enough for a poster?
Around 150 effective DPI is a practical target for posters viewed from a short distance. The preview warns you when the selected size drops below 100 DPI.
Is my image uploaded?
No. Image decoding, page rendering, and PDF creation all run locally in your browser.
