Apply one consistent 35×45mm-style frame across a batch so every applicant photo matches the same pixel grid.
Visa portals often specify millimeters and dpi. A widely used digital equivalent for 35×45mm at 300dpi is 413×531 pixels — useful when you already have high-resolution shots and need uniform exports.
Use Bulk Resize with the Visa Photo (35×45 mm) preset. For US-style square 2×2 photos, use the passport photo resizer guide instead. Browse every preset on the document photo guides hub.
