How It Works
Keep Screen On With One Click
Use NoSleepScreen when you need a display to stay awake without changing system settings or installing a browser extension.
1. Open the Tool
Go to the homepage and press the wake lock button. NoSleepScreen asks your browser to prevent screen sleep through the standard Wake Lock API when that feature is available.
2. Keep the Tab Open
The wake lock is active while the page is open and visible. This makes it ideal for dashboards, hands-free reading, cooking from a recipe, presentations, classrooms, meetings, and temporary display tasks.
3. Watch the Status
The interface shows whether screen awake mode is ready, active, unsupported, or released by the browser. If the tab becomes hidden or the browser releases the lock, NoSleepScreen tries to restore it when you return.
4. Stop Anytime
Press Stop Wake Lock or close the tab when you want normal screen sleep behavior again. For best results, plug in during long sessions and use reasonable brightness to reduce battery drain.
