"The size was right, but it still got rejected" — a common ID-photo stumble. The cause usually isn't the size itself, but the face being slightly off in scale or position relative to the spec.
These are hard to judge by eye. mynaphoto checks official compliance automatically with AI and fixes it before you submit.
An ID photo spec is about more than size.
| Item | Detail |
|---|---|
| Face ratio | Crown-to-chin size relative to the whole photo |
| Face position | Centered and front-facing |
| Size / pixels | Matches the document's spec |
| Background | Plain, light color; no shadows or clutter |
| Tilt | Face and shoulders level and front-on |
Passport photos follow the ICAO (International Civil Aviation Organization) standard, which specifies face ratio and position precisely — missing it is a common rejection cause.
