The photograph

Drag each marker, or select one and use the arrow keys. Moving a marker sideways moves the centre line the face is cropped around.

Which specification

These are the published figures. The issuing authority’s current guidance is what counts, and this gives you a number to check against it rather than a crop to trust.

The finished photograph

Several on one print

How it works

PASSPORT makes an identity photo that passes on the measurements authorities actually check, above all head height, stated in millimetres. Place the markers, choose the country's size, and it crops to the right proportions and can lay several copies onto one 6 by 4 print to save money at the photo counter. The photo stays on your device.
