ID Photo Size & Pixel Converter — One Photo, Every Format (2026)
A resume needs one size, a passport another, My Number a different pixel count again — every Japanese document has its own ID photo spec, and matching each one is more tedious than it sounds. Doing it by hand in an editing app often throws off the aspect ratio or crops your face.
mynaphoto's size converter turns one photo into the exact size and pixels for every format automatically.
Common ID photo sizes
Documents specify both millimeters (print) and pixels (data).
| Document | Data size (px) |
|---|---|
| Resume / OpenES | 450 × 600 |
| My Number Card | 480 × 617 |
| Passport | 600 × 800 |
| US Visa | 800 × 800 |
The full list is in our ID photo size guide. Print millimeters and online pixels are different — use the one that matches how you'll submit.

Tips for the original photo
A little margin while shooting gives the converter more to work with.
- Leave space around your head — room to crop to each aspect ratio
- Shoot front-on and upright — a stable face position gives a natural result
- Shoot at high resolution — quality holds up even when scaling to larger sizes
