DPI (dots per inch) links print millimetres to digital pixels. Formula: pixels = (mm ÷ 25.4) × DPI. Most passport documents in our catalog use 300 DPI — so 35×45 mm becomes 413×531 px and 51×51 mm becomes 600×600 px.

Why DPI matters for uploads
Embassy validators infer expected pixels from published mm size.

Embassy validators infer expected pixels from published mm size. Exporting at the wrong DPI places head-height bands incorrectly even if the JPEG looks sharp on your phone screen.

Frequently asked questions
What DPI for US passport photo?
300 DPI — 600×600 pixels for 51×51 mm.
Can I use 72 DPI screen resolution?
No — always export at the document’s catalog DPI for submission.
Why does Singapore use 290 DPI?
ICA publishes an exact 400×514 px digital size; our catalog stores the derived DPI for that pair.
Does higher DPI mean better approval odds?
Only when the authority asks for it (e.g. nz-passport at 600 DPI). Otherwise match catalog pixels exactly.
