Overview
ScreenWhite is a free web tool that fills any display with pure white in a single click, no signup required. It is handy as fill light for video calls, a light table for tracing, or a quick dead pixel check. The page paints in the first frame and works across desktops, phones, and tablets.
Key Features
- Fullscreen button: Tap it or press F to turn the whole screen white and hide all on-page elements until you exit.
- Brightness and warmth sliders: Adjust from 10% to 100% brightness and 2000K to 9000K color temperature so the white matches your room light.
- Keep awake option: Enables the browser wake lock, preventing the display from going to sleep while the page is open.
- Timer: Set a countdown from 1 to 60 minutes to stop the white screen automatically, useful for timed light sessions.
- Download panel: Create white PNG, JPG, or WEBP images from 1x1 up to 7680x4320, with no watermark and no files stored on the server.
Whether it is for a video call glow, a tracing surface, or a display check, ScreenWhite keeps things free, private, and quick.
