Verify before you print: these figures are consistently published for South Korea and follow the ICAO Doc 9303 standard, but we have not read them off a government page ourselves. Requirements change — India moved from 51×51mm to 35×45mm in September 2025 — and the instruction from the office handling your application always wins. Issuing authority
Making the photo
Physical size is what the authority specifies, so work in millimetres and let the pixels follow. At 300 DPI, 35×45mm is exactly 413×531 pixels — that is the number most upload forms quote, and it is the same photo, not a different one.
A phone photo is not the right shape, so it has to be cropped to 35:45 before resizing — squashing it to fit distorts your face and gets the application rejected. The Passport & Visa Photo Maker centre-crops, sizes to the exact millimetres, and can lay out a 4×6in sheet of copies for a print shop. It runs entirely in your browser — your photo is never uploaded.
