The 35 × 45 mm print format is common for Schengen applications, but photo rules vary by destination and application channel. The signed-in Voyalo tool checks framing, background and quality against the format you select.
The checker is listed as free for account holders; sign-in is required. No photo is accepted on this public page. Confirm the rules with the receiving authority. Voyalo is not a government agency; tool guidance is not an official acceptance decision.
