What is a white screen used for?
A white screen turns a display into a flat, even surface of one colour, used for lighting, backdrops, tracing and checking a panel for faults.
A plain white screen is the most useful blank surface a display can make. It throws even, neutral light across your face on a video call, backlights thin paper for tracing, shows up dust and specks that vanish against ordinary content, and reveals dead pixels, which stay dark when everything around them is lit.
- Fill light for video calls — set the screen beside your face and raise brightness until the shadows soften.
- A light table for tracing — lay paper on a tablet or laptop screen and the lines show straight through.
- Spotting specks and dead pixels — foreign material and permanently dark pixels are hardest to miss against a white field.
If you need a file rather than a lit screen, the white screen 1×1 download page lists every size with its real file size. The black screen is the opposite reference and the one to use on OLED, the cream screen is a warmer white for long reading, and the dead pixel test cycles through this and five other fields to check a panel properly.
How do you make your screen white?
Open this page and press Full screen, or press F. The colour fills the display and every other element disappears until you press Escape.
The colour is painted before any script runs, so there is no flash of white before the page settles. On a phone or tablet, add the page to your home screen and it opens straight into the screen with no browser interface at all.
Is a white screen website safe to use?
Yes. This page changes the colour of a browser tab and nothing else. It installs nothing, needs no account, and stores nothing about you.
The only thing it asks the browser for is a wake lock, and only when you switch Keep awake on. Downloads are generated on request and never stored. There is no upload path, so nothing can leave your device.
How bright is a white screen compared with a ring light?
Much dimmer. A phone or laptop screen is a useful fill light up close, but it cannot compete with a dedicated LED panel at any distance.
A screen is a large, soft, low-output source, which is exactly why it flatters faces: the light wraps rather than punches. Move it closer rather than turning it up, since halving the distance is worth far more than any brightness setting. Warm it past 4000K if the rest of the room is lit by bulbs rather than daylight.
Does a white screen stop the display going to sleep on its own?
Only if you switch Keep awake on. A web page cannot keep a display lit unless it explicitly asks for a wake lock.
The Screen Wake Lock API is what makes this possible. It works in current versions of Chrome, Edge, Safari and most mobile browsers, requires a secure connection, and may be missing on older devices. Where it is unavailable the toggle is disabled rather than silently doing nothing.
Is looking at a white screen bad for your eyes?
Not inherently, but a bright screen close to your face for a long stretch causes strain. Lower the brightness and warm the colour temperature.
Digital eye strain comes from reduced blink rate and sustained focus at one distance rather than from the colour itself. Drop the brightness slider to around 60%, warm the temperature past 4000K, and follow the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds.
Will my screen go to sleep while this is open?
Not with Keep awake switched on. It holds a browser wake lock, which asks the operating system to keep the display on with no input.
The wake lock is released the moment you leave the page, so it cannot keep your screen on by accident. Browsers also drop the lock whenever the tab is hidden; this page takes it again automatically when you come back.
How do you download a white background image?
Open the download panel, choose a format and a size, and the white image is generated and saved immediately. No watermark, no account.
PNG, JPG and WEBP are available from a single pixel up to 8K (7680 × 4320). PNG files are generated on the server as a one-bit palette image, which is why even an 8K download is only a few kilobytes. Direct links work too: white-1920x1080.png.
Does the white screen work on a phone, tablet or TV?
Yes, on any device with a browser. Add it to your home screen on mobile, or open the link in a TV browser and tap once.
On iOS, Safari does not allow a web page to enter true fullscreen, so the page fills the viewport instead and the result is the same once you add it to your home screen. On a TV, casting the tab also works.
Can you get a screen in an exact shade rather than this white?
Yes. Every hex code has its own page: put the six characters after /screen/ and that link opens the exact shade on any device.
This white is #FFFFFF. Any other shade works the same way: put its six characters after /screen/ and that address opens the exact colour. Because the colour travels in the URL, sending someone the link is a reliable way to agree on a shade without screenshots or colour pickers. The named colour screens all have their own pages, and the screensavers, prank screens and display tests live in the full list of screen tools.
How this tool works
Specifics, because “it turns the screen white” is not much of an explanation.
- The colour is in the HTML, not the CSS. Each page carries its colour as an inline style on the element itself, so the browser paints it in the first frame — before the stylesheet loads and before any script runs. That is why there is no flash of white on the black screen.
- Brightness and warmth change the colour, not a filter. Moving the temperature slider converts a Kelvin value to red, green and blue multipliers and recomputes the actual colour, rather than laying a CSS filter over the top. A filter would tint the controls too, and would cost a compositing pass on every frame.
- PNG downloads are built by hand on the server. There is no image library. A solid colour is written directly as a one-bit palette PNG, which is why an 8K download — 7680 × 4320, over 33 million pixels — comes back in about four kilobytes. JPG and WEBP are encoded in your browser instead, since those formats have no comparable shortcut.
- Keep awake uses the browser’s own wake lock. It asks the operating system to keep the display on and releases it the moment you leave. Browsers drop the lock whenever the tab is hidden, so the page takes it again when you come back.
- There is no database. Your settings live in the address bar, which is what makes a link reproduce your exact setup on someone else’s device. Nothing about your visit is stored.
- The page is about six kilobytes. No frameworks, one stylesheet, no web fonts beyond a single family. Speed is the main thing this site has over the alternatives, so it is guarded deliberately.
