A white screen tool turns your entire display into a bright, solid white surface. It sounds almost too simple to be useful, and that's exactly why it works: a clean white screen makes dust and fingerprints visible for cleaning, reveals dead or stuck pixels, and gives you a soft light source for video calls, all without installing anything.

Works instantly in any browser, on desktop or mobile, with no sign-up and no download. It's also where this site's name comes from: not just a white screen, but the whitest one your display can actually show.

How to use it

  1. Pick a color from the swatches, or enter a custom hex value in Settings.

  3. Open Settings for brightness, color temperature, Keep Awake, OLED protection, or to download the color as a PNG.

Frequently asked questions

Is a white screen safe for my eyes?
Yes, at a comfortable brightness. A full-brightness white screen viewed up close for a long time can cause eye strain, the same as any bright display. Lower the brightness slider or take breaks if you're using it for an extended session.
Does this drain my battery or affect my OLED screen?
A full white screen uses more power than a dark background because it lights every sub-pixel at once, especially on OLED and AMOLED displays. If you're worried about OLED wear from extended static use, turn on OLED Protection in Settings, which gently varies brightness every 30 seconds.
Will this work on my phone or tablet?
Yes, it works in any modern mobile browser. On iPhone, true fullscreen mode is limited by iOS itself rather than by this tool. See the next question for the workaround.
Can I download this as an image?
Yes. Pick a color, then use the Download option in Settings to save a PNG at your chosen resolution.
Why won't fullscreen work properly on my iPhone?
Apple restricts true fullscreen mode for regular web pages on iPhone, and that restriction applies to every browser on iOS, not just Safari, since Apple requires all iOS browsers to use its WebKit engine. On iPhone, this tool switches to a full-page view automatically instead. For the closest thing to true fullscreen, swipe down from the address bar and choose "Hide Toolbar."

Cedrick Reese built this white screen for WhitestScreen.com. The white is a plain #FFFFFF background color set by your browser, not a photo, so there's no compression or tint between the color and your panel. Brightness, color temperature, and the OLED protection option (which shifts brightness 3% up or down every 30 seconds) all run on your device. Nothing on this page depends on outside data, so there's nothing that can go out of date.
