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 413 × 531 px, enlarging it only blurs the face.

- Guichet.lu says the identity-card photo is generally taken on the spot during the application.
- This applies at the Guichet.lu reception desk or in the commune of residence.
- Applicants normally do not need to bring a photo for the standard route.
- Special routes can allow an ICAO-compliant recent photo to be scanned.
- This confirms a mainly authority-managed image route with exceptional applicant-photo handling.
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 Luxembourg 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 35 × 45 mm result — print it or attach it to the application
