What these millimetres work out to
- In a 30 × 40 mm frame a head band of 70–80% is 28–32 mm from the chin to the crown.
- Of the 40 mm of height that leaves 8–12 mm for the gap above the crown and the space below the chin together.
- At 300 dpi that is a head 331–378 pixels tall — below 331 px the file is too small to print, however good the crop is.
- Against the European 35 × 45 mm standard this frame is 0.86 times as wide, 0.89 times as tall and 0.76 times the area — a photo cut for one of the two cannot be reused for the other.
How to crop it, in three steps
- 01
Upload a photo taken face-on, in even light
- 02
The tool finds the face and aligns the frame itself — check that the head lands in 70–80%
- 03
Save the 30 × 40 mm result — print it or attach it to the application
Do not confuse it with another Vietnam document
Vietnam does not use one frame for everything. This page is about driver's license — 30 × 40 mm. The documents below are cut to a different size, so a file prepared here will not fit them.
- visa 40 × 60 mm
- work permit 40 × 60 mm
- temporary residence card 20 × 30 mm
What we fix for free, and what AI fixes
Fixed for free
- Background. Replaced with the one this document asks for: plain white background.
- Head tilt. Straightened if the head leans slightly to one side.
- Frame. Exactly 30 × 40 mm, by the document’s rules.
- A light shadow on one side of the face. Gently brightened.
- File and print sheet. A file to the document’s rules and a 10 × 15 or A4 sheet to print.
What can't be fixed for free, AI correction fixes
- Hard shadows and uneven light on the face.
- A smile, raised brows or a half-open mouth. Cropping keeps the face it was given.
- Too few pixels. If the original is smaller than 354 × 472 px, enlarging it only blurs the face.
- Clothing and pose. Shoulders out of frame, body turned away from the camera.
Glare on the lenses. Take the glasses off or turn away from the light source and shoot again.
One thing that is specific to Vietnam
- Online driving licence service: a 3 × 4 cm photograph on a white background, file up to 700 KB; head tilted no more than 5°, mouth closed, eyes open; avoid white and black clothing; no thick-framed or dark-lensed glasses (only clear small-frame glasses, removal recommended).
Printing on a single sheet
4 × 2 frames fit on one 10×15 cm sheet — 8 copies from a single print.
Print at 100% scale, borderless, and turn off fit-to-page so each photo keeps its exact size.
