Shared standards do not mean identical portals
European visa rules reference ICAO photographic standards, while each national authority can publish its own digital format, KB, dimension, and upload instructions.
Use the rule shown in your application
Select the EU / Schengen custom profile, then copy the current minimum and maximum file size, required dimensions, and accepted format from the specific country portal.
Avoid false “EU compliant” promises
A technical converter cannot verify biometric suitability or guarantee acceptance across every member state. The EU Visa Code provides the common regulatory context; the destination authority supplies the operational upload rule.
