Features
Check the result before you print.
PosterSplit brings paper size, margins, overlap, scale, and assembly guides together so large prints are easier to prepare with a home or office printer.
02
Photos, PDFs, and SVGs
Use images for posters, PDF drawings for reference, or SVG artwork for clean line output. Pick the source that fits what you are making.
03
Assembly guides included
Page numbers, matching labels, overlap areas, and cut lines help you see where to trim and how each sheet connects after printing.
04
Printer calibration
Compensate for subtle horizontal or vertical scaling differences caused by printers and drivers, especially useful for full-size patterns and drawings.
05
A larger workspace on Mac
On Mac, preview your poster on a wide canvas while adjusting source, paper, size, guides, and export settings side by side.
06
On-device processing
Core source handling and PDF generation are performed on your device. Your photos and drawings are not uploaded to a developer-operated server.
Workflow
Choose. Adjust. Export.
PosterSplit turns large-format printing into a simple three-step flow. You can make the key decisions in order, even if you do not use professional print software every day.
