About
[*] what is this
a free browser tool that keeps your screen awake — no download, no account, no setup.
Keep Screen On is a simple online utility built for one job: preventing your device screen from sleeping while you work, read, present, cook, or watch tutorials.
It works entirely in your browser using the Screen Wake Lock API with a video-based fallback for broader compatibility. No data leaves your device.
