How to use

  1. Choose JPG, PNG, still WebP or PDF. For a PDF, select the one page to enlarge.
  2. Set target width in mm, A4 or Letter paper, orientation, margins and overlap. Review the sheet count and source resolution.
  3. Save the tiled PDF and print at Actual Size / 100%. Disable Fit, automatic scaling, Borderless and a second poster split in the viewer.

A worked example

A 600mm × 400mm image on portrait A4 with 10mm margins and 5mm overlap produces 4 columns × 2 rows, or 8 PDF pages. Assemble left to right, one row at a time. Test two adjacent sheets for size and alignment before printing the rest.

Before entering, saving or printing

Password-protected PDFs, annotations/forms on the target page, Word and animated WebP are unsupported. Enlargement cannot create missing detail.
