Do not confuse it with another Thailand document
Thailand 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.

What we fix for free, and what AI fixes
Fixed for free
- Background. Replaced with the one this document asks for: plain light background without textures, shadows, or foreign objects.
- 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.

Where these numbers come from
Source: Department of Land Transport of Thailand. Last checked against the official page on 17 May 2026.
What the source confirms
- The Department of Land Transport legal instruction applies to vehicle registration, tax, driving licences and driver-related services.
- It says civil-registry database records should be used instead of copies of ID-card and house-registration photos for covered DLT matters.
- This confirms that the Thai driving-licence route is authority-managed rather than a standard applicant-supplied print-photo route.
- The public DLT source does not publish an applicant-supplied print-photo size for this workflow.
- This page therefore explains the authority/civil-registry image route instead of treating the licence as a reusable home-print photo.
