Before you print.

This free tool helps you divide your own image into a tiled poster PDF. You retain your rights to your image and output.

Your materials

Use images that you own or have permission to reproduce. The sample illustration supplied with this tool may be used to test the printing workflow.

Printing and output

Print settings, available margins and colour vary by device and printer. Check the paper size and orientation, print at Actual size, and test one sheet before printing a full set. Export is rasterized at 144 DPI and cannot restore detail missing from the original image.

Availability

The tool is provided as available. We do not guarantee compatibility with every file, browser, printer or paper stock. The current limits are 20 MB per image, 48 megapixels, 16,000 pixels per side, and 64 poster sheets.

Libraries

PDF export uses pdf-lib, distributed under the MIT licence.
