How it works

1 Add your photo.
2 Choose cm, mm or inches, type the size and pick a DPI (300 is standard for printing).
3 Download. The file stores the size, so it prints at exactly that size.

What DPI should I choose?

300 DPI for printing photos and documents. Use 200 if a form asks for it, or 72–96 for screens only.

How many pixels is 3.5 × 4.5 cm at 300 DPI?

413 × 531 pixels. The tool shows the pixel size as you type, so you can check it against any form’s rules.

Will it print at the right size?

Yes. We save the DPI inside JPG and PNG files, so printing software uses the size you set.
