Live guides and checks for the U.S. State Department photo rules. Everything runs on your phone; no photo is uploaded.
Photo output: 1200×1200 px JPEG (2×2 in), head 1–1⅜ in (50–69% of height), eyes 1⅛–1⅜ in from the bottom (56–69%), white background. This tool helps you follow the rules but cannot promise the passport office will accept the photo.
Use the single photo for online renewal. Print the 4×6 sheet at 100% (no cropping or "fit") at any photo kiosk, then cut out a 2×2 in photo.
