What Keep Screen Awake does
Keep Screen Awake keeps your screen from dimming or locking while this page is open and visible. Pick how long you need, press Start, and leave the tab in front.
It's useful when you're reading a long document, following a recipe, watching a dashboard, or showing something to the people around you. When the time runs out, or you press Stop, your screen goes back to its normal behavior.
It doesn't change your device's settings, and it doesn't stop your computer from sleeping for other reasons. It only asks the browser to keep the display on while you're looking at this page.
Choose a preset from 15 minutes to 4 hours, Unlimited, or a custom length up to 24 hours. A timed session ends by itself, which is handy if you might walk away and forget. Your last choice is remembered for next time, and the remaining time shows in the browser tab so you can check it at a glance.
How Screen Wake Lock works
Modern browsers include a feature called Screen Wake Lock. A page can ask the browser, "please keep the screen on for now," and the browser agrees as long as the page stays visible.
WakeMode only makes that request after you press Start, never when the page loads. The browser can take the lock back at any time, for example when you switch tabs or your battery runs low. When that happens, the status changes to Interrupted, and WakeMode asks again as soon as the page is visible.
The elapsed and remaining times keep counting the whole way through, so your session length stays accurate.
The lock is tied to this one page. If you open WakeMode in two tabs, only the tab you're looking at holds it. Closing the page, reloading it or navigating away releases the lock immediately, so nothing keeps running in the background after you leave.
Screen Wake Lock is supported in current versions of Chrome, Edge, Safari, Firefox and Opera. If your browser is too old, the tool tells you before you press Start, and the steps further down show how to change your device's own screen timeout instead.
Why your screen might still turn off
The tab is hidden or minimized
Browsers release the lock when the page can't be seen. Keep the tab in front, and don't minimize the window. When you come back, WakeMode turns the lock back on by itself.
Low battery or power saver
Battery saver and Low Power Mode can refuse or cancel the lock. Plug in, or turn power saving off while you need the screen on.
An older iPhone or iPad
Safari supports Screen Wake Lock from iOS and iPadOS 16.4. On older versions, update your device or use the Auto-Lock setting below.
A managed work device
Some organizations enforce a screen lock after a set time, and a web page can't override that. Ask your IT team if the screen still locks.
The lid is closed
Closing a laptop lid usually turns off the display or sleeps the computer, whatever any page asks. Keep the lid open.
Other ways to keep your screen on
If your browser doesn't support Screen Wake Lock, or you want the screen to stay on everywhere and not just on this page, you can change your device's own timeout. Remember to set it back afterwards, since a screen that never turns off uses more battery and leaves your device unlocked. Menu names can vary slightly between versions.
Windows 11
- Open Settings, then System, then Power & battery.
- Open Screen, sleep, & hibernate timeouts (called Screen and sleep on some versions).
- Set the times for turning off your screen to a longer value, or Never.
macOS
- Open the Apple menu, then System Settings, then Lock Screen.
- Change Turn display off on battery when inactive, and Turn display off on power adapter when inactive, to a longer value or Never.
iPhone and iPad
- Open Settings, then Display & Brightness, then Auto-Lock.
- Choose a longer time or Never.
Auto-Lock is fixed at 30 seconds while Low Power Mode is on.
Android
- Open Settings, then Display.
- Tap Screen timeout and choose a longer time.
Names and the longest option vary by manufacturer.
On work laptops, your IT team may lock these settings. If they're greyed out, that's why.
Does this install anything, and is it private?
Nothing is installed. The tool runs entirely in your browser, and closing the tab ends it.
No account is needed, and nothing you do here is sent to us. The only thing saved is your last chosen duration, kept in your own browser so it's ready next time.
There are no extensions to trust and no background apps that keep running after you're done. You can clear the saved duration at any time by clearing this site's data in your browser settings.
Nothing to install
No app, extension or account. Open the page and press Start.
Works on phones and computers
Use it in recent versions of the major browsers on desktop and mobile.
Stops when you close the page
Close the tab or press Stop, and your screen behaves normally again.
