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.
- id card 40 × 60 mm
- passport 40 × 60 mm
- residence permit 40 × 60 mm
- visa 40 × 60 mm
What cropping will not fix
- A wrong background — cropping does not repaint the wall behind you. This document needs: plain light
- A shadow on the face or on the wall. Step 1–2 m away from the wall and shoot facing a window.
- Glare on the lenses. Take the glasses off or turn away from the light source and shoot again.
- 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.
Thailand-specific things to know
- ON-SITE capture at DLT offices (no BYO photo)

Where these numbers come from
Source: Department of Land Transport of Thailand. Last checked against the official page on 2026-05-17.
- 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.
What the cropper is still good for here
It will not produce the official photo for this document. It is here for the neighbouring jobs: a portrait for the application form, a copy for your own records, or another Thailand document that does accept a photo you prepared yourself.
The photo is cropped in your browser. It is not uploaded to a server and we do not store it.
How to crop it, in three steps
- Upload a photo taken face-on, in even light
- Move the photo until the eyes sit on the guide line and the head fills 70–80%
- Save the 30 × 40 mm result — print it or attach it to the application
