Tile ID photos onto a print sheet
Fill a sheet of photo paper with copies of your cropped ID photo so one print gives you several. A convenience-store L-size print in Japan costs 30-40 yen, far less than a photo booth.

How many fit on one sheet
With a 3 mm margin, an L-size sheet (89 x 127 mm) holds eight 30 x 40 mm photos, four 35 x 45 mm, or twelve 24 x 30 mm. A4 holds around 45 at 30 x 40 mm. Pick a paper and a size and the count is calculated instantly; the photo is turned sideways automatically when that fits more copies.
Printing at a convenience store
Take the exported JPEG on a USB stick or through the chain's print app, then choose "photo print" and "L size" — not "plain paper", which has no gloss and is not usable as an ID photo. Choose borderless so the sheet is filled edge to edge.
Cut lines and margins
Cut lines draw a hairline around each photo as a cutting guide; aim for the centre of the line, since cutting inside it makes the photo slightly small. The margin is adjustable from 0 to 10 mm — raise it if your printer struggles with borderless output.
Frequently asked questions
Should I print the JPEG or the PDF?
For a convenience-store photo print, use the JPEG — a PDF is treated as a plain-paper document there. For an A4 print at home, the PDF carries the page size and is more likely to come out at true scale.
The printed photos came out slightly the wrong size
That is the printer's "fit to page" scaling. Set scaling to none or 100% in the print dialog. The output carries a real 300 dpi tag, so at 100% it prints at true size. Measure one photo with a ruler to confirm.
Why did my photo get rotated?
Only the arrangement on the sheet rotates, when doing so fits more copies. The photos themselves keep the aspect ratio you chose.
Can I mix different sizes on one sheet?
Not currently — one size per sheet. Run the layout twice and print two sheets; at 30 yen each that is still cheap.
