Questions and answers
How does it keep my screen awake?
Your browser has a built-in feature called the Screen Wake Lock API. When you press the button, this page asks the browser to keep the screen on. Everything happens on your device and nothing is sent anywhere.
Why does my screen still sleep when I minimize the window?
Browsers release the lock when a page is hidden. Open the floating window: while it is open, the lock is held from that small window, so you can use other apps or minimize this one.
The floating window goes behind other windows. Can I fix it?
Staying on top is decided by your operating system and desktop. On some Linux desktops, such as KDE Plasma, right-click the title bar of the floating window and choose More Actions, then Keep Above Others.
Does it work when I close the laptop lid or the computer sleeps by itself?
No. Closing the lid, pressing a sleep button or a forced system sleep cannot be prevented by any website. The screen can also turn off when the battery is low or battery saver is on.
Which browsers are supported?
Keeping the screen awake works in Chrome and Edge 84 or newer, Firefox 126 or newer, and Safari 16.4 or newer (caniuse data, October 2026). The floating window needs Chrome or Edge 116 or newer, or Firefox 151 or newer, and is not available in Safari. The page tells you when something is not available.
What are the timer limits?
Choose a preset, any number of minutes from 1 to 720 (12 hours), or a time of day within the next 12 hours. You can add 15 minutes at any time. When the timer ends, the screen is allowed to sleep again.
Is it private?
Yes. There are no cookies, no analytics and no requests to other websites. Your timer choice is stored only in your browser. See the privacy page.
Does it use more battery?
A screen that stays on uses more power than one that turns off. Use a timer so it switches off by itself.
