A browser-based tool turns an image into a tiled, print-ready PDF for assembling into a large poster from ordinary paper.

Landing page captured for the 2026-10-23 issue.

For: People printing oversized posters on home printers
Worth noticing: A calibration sheet lets users measure a 100 mm line so the exported pages can compensate for printer scaling.

Field notes

The workflow includes controls for sheet width, safe margin, overlap, orientation, and output quality, with a live preview intended to show the page grid. A separate calibration PDF uses a measured 100 mm line: the user enters the measured length to correct for printer scaling. The print guide recommends disabling “Fit to page” and printing at Actual Size or 100%.
