Keep Screen On uses the Screen Wake Lock API when available, and falls back to a video-based no-sleep method for broader browser support.

Is it safe and private?

Yes. Everything runs locally in your browser. No data is collected, no accounts required, and no software is installed on your device.

Which devices and browsers are supported?

It works on all modern desktop and mobile browsers including Chrome, Edge, Safari, and Firefox on Windows, macOS, Linux, Android, and iOS.

Does it work on iPhone and iPad?

Yes. It works on iPhone and iPad using Safari or Chrome. The Screen Wake Lock API is supported in Safari on iOS 16.4 and later, and on iPadOS 16.4 and later.

Does it work on Android phones and tablets, including Huawei?

Yes. It works on Android devices including Samsung, Xiaomi, OPPO, and Huawei phones and tablets. Use Chrome or your default browser for the best experience.

Does Keep Screen On drain my battery?

Keeping the display lit uses more power than letting it sleep, the same as any time your screen stays on. Nothing runs in the background — toggle it off or close the tab and your device returns to normal power use. For long sessions, keep your device plugged in.

Does it keep the screen on when the tab is in the background?

No. The wake lock stays active only while this tab is visible and in front. If you switch to another app or tab, or minimize the browser, the system releases the lock and your screen can sleep again. Keep the tab open and on top for continuous wake.

Will my screen stay on if I lock the phone manually?

No. Pressing the power button to lock your device always overrides the wake lock — that is a hardware action the browser cannot block. The tool only prevents the automatic screen timeout, not a manual lock.

Is Keep Screen On really free?

Yes, completely free with no account, no sign-up, and no paywall. There is nothing to buy and no trial — just open the page and switch it on.

Do I need to install an app or extension?

No installation of any kind. It runs entirely in your browser using standard web APIs, so there is no app, extension, or plugin to download.

Can I use it while watching videos or streaming?

Yes. It is handy when you are watching a live stream, a slow-loading video, or a dashboard that would otherwise dim mid-view. Just keep this tab active alongside your content.

What is the Screen Wake Lock API?

It is a modern browser feature that lets a web page ask the operating system not to dim or lock the screen. The tool requests this lock when you activate it and releases it when you turn it off or leave the page. On browsers without Wake Lock support, it falls back to a tiny looping video to achieve the same effect.

Does it work on Windows and Mac laptops?

Yes. On Windows 10 and 11 and on macOS it keeps the display awake in Chrome, Edge, Firefox, and Safari. It is useful during downloads, long reads, or presentations when you do not want the laptop screen to dim.

What is Keep Screen On?

Every phone, tablet, and laptop dims and locks its screen after a short idle timeout to save battery. That is fine most of the time — but not when you are following a recipe with messy hands, reading a long article, watching a live dashboard, or waiting on a download. Keep Screen On is a free browser tool that holds your display awake so it never dims or sleeps while you need it, without changing any system settings or installing anything.

Just open the page, tap the button, and your screen stays lit until you switch it off. Everything happens locally in your browser — no account, no tracking, and no data ever leaves your device. It behaves the same across Windows, macOS, Linux, Android, iPhone, iPad, and Huawei, giving you one simple no-sleep switch on every device you own.

Behind the button, Keep Screen On uses the browser Screen Wake Lock API to ask your operating system not to dim or lock the display. When Wake Lock is not available, it falls back to a tiny looping video that produces the same effect, so the tool works across older browsers too. The lock stays active only while this tab is open and in front — switch away and your device returns to its normal timeout automatically. Nothing is stored, and turning the switch off or closing the tab instantly releases the lock.
