Document photo rules should be easy to understand
Foto3x4 combines a focused iPhone workflow with free, source-linked guides for passport, visa and ID photo requirements.
Why we built it
Photo rules vary by country and document. The outer size is only one part: face height, background, expression and file format can all change. Foto3x4 keeps those checks together.
How we publish requirements
Each detailed requirement page links to the issuing authority or government source used during review. We show the verification date and avoid opening pages that do not provide distinct value.
What the app does
The iPhone app helps select a document preset, align the face, prepare the background and export a digital file or print layout. The final acceptance decision always belongs to the issuing authority.
