Keep Screen Awake
Prevent your device from sleeping while this page remains open.
Ready when you are.
How it works
This tool uses the browser Wake Lock API to ask your operating system to keep the display on. When active, the screen will not dim or turn off on its own. The lock is released automatically when you stop the tool, switch tabs, or close the page. Nothing is sent to a server.
Wake locks apply only to the display — they do not prevent your computer from entering system sleep if you close the lid or trigger it manually.
FAQ
What is a Screen Wake Lock?
A Screen Wake Lock is a browser API that allows a web page to request that the device keep its display on. When a wake lock is active, the operating system is instructed to suppress the automatic screen timeout that would normally dim or turn off the display.
Can a website keep my screen awake?
Yes, in browsers that support the Wake Lock API. The browser requests permission from the operating system to prevent the screen from turning off. No special permissions dialog is shown to the user — the page simply makes the request when you activate the tool. Chrome, Edge, and Android Chrome support this feature. Safari and Firefox do not yet support it.
Does Keep Screen Awake drain battery?
Yes, keeping your screen on continuously will use more battery than allowing it to dim and sleep. The exact impact depends on your screen brightness and device. On laptops and phones, the display is typically the largest source of power consumption, so expect a noticeable reduction in battery life if you keep the screen awake for long sessions. Lowering your screen brightness can offset some of this.
