About White Screen Free
White Screen Free is a small, deliberately simple set of browser tools for anything that needs a controlled, full-screen image: cleaning a monitor, testing a panel, lighting a video call, or just blanking a display.
The whole site is static HTML. There is no framework loading in the background, no account system, and no image processing on a server — every tool renders on your own device, which is why it still works when you are offline.
We built it because the existing tools were either bloated with megabytes of script, or so bare they could not adjust brightness. This one aims for both: instant to load, and genuinely capable once it is open.
