It depends on the image size and the paper. The count and grid (for example 5 × 6) appear as soon as you change anything, and Auto orientation picks portrait or landscape, whichever fits more copies.

If the shape of your photo differs from the image size you enter, the photo is cropped to fill the box. You can drag the sheet preview to choose which part of the photo stays (double-click to centre it again).

A4, Letter, A5 and 4 × 6 in. Every sheet keeps a 5 mm margin and a 2 mm gap between images, with dashed guides to cut along.

Use 300 dpi for sharp prints. 150 dpi makes a smaller file that is fine for drafts, and 600 dpi is the finest, though it only helps if your photo has enough pixels. DPI sets how much detail is stored for each image; the size on paper stays exactly what you entered.

PDF is best for printing because the page is exactly the paper size and each image keeps its real size in millimetres. JPG or PNG suit online print shops that only accept an image.

Print the PDF at 100% or Actual size. Options such as Fit to page or Shrink to fit make every image smaller than the size you chose. Most home printers also cannot print to the very edge of the paper, which is why the sheet keeps a margin.

No. It places your photo at the size you enter and repeats it on the sheet. It does not check face position, head size, background colour or any other official requirement, so confirm those with the authority that asked for the photo.

An image can be 10 to 1000 mm on each side, with at most 500 copies on one sheet.

No. The sheet is built in your browser, so the photo never leaves your device.
