Use a second monitor or laptop as soft face fill when a ring light is not available.
Even backlight makes dust, oil, and smudges obvious before you wipe the panel.
A calm white field for tracing, sketching under paper, or cutting visual noise.
Spot uneven backlight or obvious panel defects before a full dead-pixel sequence.
No. Fullwhite runs in the browser — no app, no account, and no extension.
Press Esc, click the stage again, or use the browser exit-fullscreen control.
Yes. Zoom Lighting adds brightness, color temperature, and optional wake lock for longer video calls. White Screen is a pure #FFFFFF field for the simplest fill, cleaning, or inspection job.
Use White Image to export 1080p, 1440p, or 4K pure white PNG from canvas in the browser — files stay on your device.
A bright full field can use more power than dark UI, especially on OLED. Use it for short tasks, lower system brightness if needed, and exit fullscreen when you are done.
No. It is a practical browser #FFFFFF field, not a lab reference. For camera-balanced meeting light, use Zoom Lighting presets instead of assuming perfect white point.
A fullscreen white screen is one of the simplest utilities on the web: open the page, go fullscreen, and you get an even #FFFFFF field edge to edge. People use it as improvised face light on a second monitor, as a bright surface for wiping fingerprints, as a calm backdrop for tracing paper, or as a quick way to notice blotchy backlight before running a full dead-pixel sequence.
Unlike a photo of a white wall, a browser white screen is uniform and free of texture. Unlike a desktop wallpaper, it is one click into true fullscreen with UI hidden so you are not fighting dock icons or browser chrome. Fullwhite keeps the path short on purpose — no signup, no install, and keyboard shortcuts (F, Space, Esc) so you can enter and leave without hunting menus mid-call.
Pick White Screen when you want pure white with zero controls: cleaning, tracing, a quick panel glance, or the fastest soft fill. Choose Zoom Lighting when you will stay on a call and need brightness, cooler or warmer temperature, and optional wake lock so the panel does not dim. Choose White Image when you need a file — a pure white PNG at 1080p, 1440p, or 4K generated locally with Canvas for slides, mockups, or design templates.
If you are hunting dead or stuck pixels, start with Dead Pixel Test for a fixed white → black → red → green → blue sequence. Color matrix pages (black, red, green, blue, and more) are available from the same nav when you need a single solid field without the full test flow.
For video, place the lit panel slightly off-axis in front of you rather than behind the camera; raise system or page brightness gradually while watching your webcam preview. For cleaning, finish with a dry microfiber pass after any liquid so you do not leave streaks under a bright field. For inspection, step back so your eyes can scan the whole panel, then lean in on any dark speck and confirm it on black and primary colors.
Fullwhite is a browser tool, not a hardware calibrator. Results depend on your display, ambient light, and camera. Use it as a convenient light and inspection surface, then switch to the specialized tool on this site when the job needs temperature control, a downloadable asset, or a structured pixel check.
