Small tool. Bigger canvas.

Poster Tiler helps adult educators, event organizers, shop owners and makers turn one image into paper pieces that fit an ordinary printer.

What the tool calculates

A4 or Letter paper, portrait or landscape, a printable rectangle inside your margin plus a 3 mm annotation gutter, and a repeated strip between neighboring sheets. It preserves your image's proportions. The PDF adds crop marks, sheet coordinates and a 100 mm check sheet.

What still needs a real printer

PDF dimensions do not certify physical output. Printer drivers, paper feed, margins and scaling can change the result. Measure the check sheet and test two seams before a large run. Physical print size has not yet been verified on a real printer. Mobile memory limits still need broader device testing.

Deliberately small

One JPG or PNG at a time. No PDF input, URL imports, AI enlargement, batch processing, cloud storage, accounts or printer-driver control. This tool is intended for adults and is not designed as a children's service.
