White Screen for X-Ray Film

A bright, even white screen works as a portable stand-in for an X-ray light box, useful for a quick look at your own film without dedicated equipment. Hold the film up to the screen at maximum brightness in a dim room for the clearest view. It's free and works instantly, no app or sign-up needed.

How to use it

1. Turn this page's brightness slider and your device's own screen brightness all the way up.
2. Dim the room and tap the fullscreen button on the white area.
3. Hold the film flat, just in front of the screen, so the light comes through evenly.

Watch out for: a phone that dims or locks mid-look cuts your light, so lengthen the screen timeout and turn off auto-brightness before you start.

Cedrick Reese built this page. It's a plain white background with a single brightness control. A phone or monitor is dimmer and less even than a dedicated medical light box, which the page says up front, along with the note that this isn't medical equipment. There's no outside data behind it.
