The 3×4 cm format is a common size for ID cards, applications and forms in many countries. This page helps you produce it from any recent portrait: the tool finds your face, centres and crops it to the 3:4 ratio, and gives you a digital file plus a print sheet that you can take to any photo shop or print at home.

The layout follows general ICAO photo guidance. Because rules differ per authority, check what your specific office asks for before printing many copies. Everything runs in your browser, so your photo is never uploaded.
