1. Pick what you are printing
A poster split across several sheets, a saddle-stitched booklet, planner refills, or a sheet of business cards. Each page asks for the paper size and the counts.
2. Load your file
Drop in a PDF or an image and it is parsed inside your browser. Nothing is uploaded, so pre-press artwork and confidential documents are safe to use here.
3. Save the print-ready PDF
You get trim marks, cut lines and glue flaps where they help. Print at home or on a convenience-store copier — just set scaling to none (100%) so the millimetres come out right.
Why nothing is uploaded
Uploading artwork or internal documents to a free conversion site puts retention and reuse in someone else's terms of service. Here the parsing, the imposition and the export all run in JavaScript, so the file never leaves your browser's memory and disappears when you close the tab.
Skip the large-format print shop
A single A1 poster from a print shop runs 3,000-6,000 yen in Japan. Tiling it onto eight A4 sheets and printing them at a convenience store costs 80-400 yen. Booklet imposition works the same way — you fix the PDF yourself instead of paying for the service.
Frequently asked questions
Will a home printer give a usable result?
Yes. The PDFs carry a true millimetre page size, so choosing "Actual size" or 100% scaling in the print dialog reproduces the exact dimensions. "Fit to page" shrinks everything by a few millimetres, which matters for business cards and planner refills.
Can I print these at a Japanese convenience store?
Yes. Put the PDF on a USB stick or upload it to Seven-Eleven netprint, Lawson or FamilyMart network printing. The machines print up to A3, so an A4 layout can also be enlarged onto A3.
Which file formats are supported?
PDF plus JPEG and PNG images; iPhone HEIC is transcoded in the browser. Output is always PDF, with paper size and margins specified in millimetres.
Is there a size limit?
There is no server-side limit because there is no server. The practical ceiling is your device's memory — a typical laptop handles a 100-page PDF or a 50 MB image comfortably.
