PassPose

PassPose checks a US passport, visa, or green card photo against the official rules: head size, eye height, background, light, and expression. The check is free and needs no account. It runs in your browser. PassPose crops and resizes the photo. It does not edit it, because the State Department rejects edited photos. The download costs US$9.99 and gives the photo file at the official size and a 4x6 sheet to print at a drugstore. PassPose is not a government site.
