Trim, match and tape
Use the row and column labels to arrange sheets. Trim the white margin along the corner crop marks. Overlap neighboring printed strips and line up the image using the dashed top/left guides. With zero overlap, butt trimmed edges together.
Before you print.
Does my image get uploaded?
No. Decoding, preview and PDF generation run on your device. We send usage events to Google Analytics, not image contents or filenames. See our privacy notice.
Will this improve a low-resolution image?
No. Enlarging does not add detail. The effective PPI estimate helps you judge whether the result may look soft. PDF exports use high-quality JPEG with white behind transparency; they are not professional color-managed proofs.
Why is the last sheet only partly filled?
The tool preserves your chosen dimensions. If the image does not fill an exact number of sheets, the final row or column has blank space. Trim at the corner crop marks. Posters are limited to 100 sheets.
How do I check my printer’s scaling?
Print our printer test page at 100% and measure its 100 mm reference line before using expensive paper.
