White Screen
A completely white screen — RGB 255, 255, 255 — filling your entire display, with every control out of the way. It loads in a fraction of a second, works on anything with a browser, and is more useful than it has any right to be: a light source, a tracing surface, a backdrop, and the fastest way to find out whether that mark on your monitor is dust or a dead pixel.
What people use the white screen for
Use a screen as a light source
A monitor or tablet at full white is a large, soft, even light. It fills shadows on a face for a video call, lights a keyboard in a dark room, or works as a torch when nothing else is to hand.
Trace drawings without a lightbox
Lay paper over a tablet or laptop showing white and the light passes through both sheets. It is the same principle as a light table, using hardware you already own — the classic trick for tracing sketches, transferring line art and copying diagrams.
Find dust, scratches and dead pixels
A dead pixel is invisible on a busy desktop and unmistakable as a black dot on a white field. Scratches and coating damage show up the same way. Check a new monitor while it is still returnable.
Check screen uniformity
A flat white field reveals whether the backlight is even across the panel. Dimmer corners, warm or cool patches, and clouding are all things you will never notice on normal content but cannot unsee on white.
Clean a screen properly
White shows dust; black shows grease. Switch between them and you can see exactly what you are wiping and whether it is actually gone.
A clean backdrop for photos and video
A white-filled screen behind a small product, or beside it as a bounce card, gives you an even white ground without buying a light tent.
How to use the white screen
- 1The white screen is already filling this page — nothing to click.
- 2Press F, or use the fullscreen button, to go edge to edge with no browser chrome.
- 3Turn your display's own brightness up if you are using it as a light — that, not the page, controls the output.
- 4Use the brightness slider to dim below full white without touching your system settings.
- 5Move the mouse or tap to bring the controls back; they hide themselves again after a few seconds.
Frequently asked questions
How do I make the white screen truly fullscreen?+
Press F or click the fullscreen button — that uses the browser's real fullscreen mode, so the tab bar, address bar and taskbar all disappear. F11 works in most desktop browsers too. Press Escape to come back.
Why would anyone need a white screen?+
Most often as a light: a screen at full white is a soft, even, dimmable panel that is already on your desk. After that it is a tracing surface, a way to inspect a display for dead pixels and dust, a photography backdrop or bounce card, and a way to check backlight uniformity.
Can I use my screen as a lightbox for tracing?+
Yes, and it works well. Put the original on the screen, blank paper on top, and turn the brightness up — for ordinary printer paper that is usually enough to see through both sheets. Do not press hard on an LCD, and avoid taping anything to the panel.
Will a white screen damage my monitor?+
No. Displaying white is what a screen does — no more stressful than any bright web page. The only thing worth avoiding is leaving any completely static image up for many hours on an OLED panel, where it can contribute to burn-in over time.
Does it work on iPhone, Android and iPad?+
Yes, in any modern mobile browser. Tap once to hide the controls. For a genuinely fullscreen launch, add the page to your home screen and open it from there.
Is it free, and do you track anything?+
Free, no account, no limit. Everything runs in your browser — your colour choices and settings never leave the device.
