When a portal asks for a small portrait file, batching one consistent 300×400 export saves time — still verify head crop and background rules.
National IDs, employee badges, and vendor portals rarely share one global size. The ID Photo (3:4) preset gives a compact 300×400portrait that fits many "upload a photo" fields when you need consistency across many headshots.
Start in Bulk Resize and pick ID Photo (3:4). For biometric 35×45mm exports, see visa photo resizer. See the full list on document photo guides.
