Passport Photo Cropper

Passport photos are one of those things where a small detail gets genuinely expensive. The booth costs money, the photographer costs more, and if the authority rejects the photo the whole game starts over. Yet you often already have a good photo on your phone - it just needs the right format and the right face position. That is exactly what this tool does.

At the core are the biometric presets. The German 35x45 format for ID card, passport and driving licence is there, as is the Schengen visa, the US 2x2 inch format for passport and visa, plus formats for the UK, China at 33x48 millimetres, India, Japan, Canada at 50x70 and Australia. For applications there is the classic 4.5x6 cm format and a compact 3.5x5 cm variant.

So the photo actually gets accepted, guidelines show the correct head position. The biometric formats have rules for how high the face must sit in the frame, and the notes on standards like ICAO help you meet them. You can zoom and move freely until chin, eyes and head height fit.

For printing there is the print sheet. Instead of expensively developing a single photo, you place several passport pictures on a 10x15 cm sheet and print them at home or at the drugstore. You can set the resolution to 300 or 600 DPI so the print stays sharp.

The photo is processed server-side with Sharp so the result is cleanly scaled and cropped - a single image, not a batch. In the end you download the finished passport photo or the print sheet. An honest note: whether an authority accepts the photo also depends on lighting, background and expression. The tool helps with format and position, the rest you bring yourself.
