A digital passport photo at 350×450

Why these numbers. 35×45 mm scaled to 10 pixels per millimetre gives 350×450 — easy to remember, and some portals use exactly that for uploaded photos.

For printing you want more pixels: 413×531 at 300 DPI. Use the 413×531 or 35×45 mm page, which saves the DPI.

Framing. Head roughly 70–80% of the height, eyes about 40% from the top, plain background. Drag the preview to line it up.

File size. Usually 15–40 KB as JPG. If a form caps it lower, use JPEG to 30 KB.

Similar: 350×467 (3:4).
