Screen Wake Lock (Prevent Sleep, Always On)

Run this tool during recipes, workouts, livestreams, or demos so your display never goes dark mid-session.

Prevent your screen from dimming on Google Meet, Zoom, or while presenting.

Force your screen to stay awake natively. By tapping into the modern Screen Wake Lock API, this utility overrides your operating system's aggressive power-saving timeouts. Stop Google Meet or Zoom from auto-sleeping your display in the middle of a lengthy presentation, a client call, or an active livestream monitoring session.

Beating the Power-Save Timeout

There is nothing more incredibly frustrating than having your screen fade to black right when your hands are covered in flour while following a recipe, or when you are three minutes into reading a critical technical document. Operating systems are aggressively optimized for battery life, but sometimes you just need the screen to stay on without digging three menus deep into your control panel to change the global timeout settings.

How We Keep You Awake

We utilize the modern Screen Wake Lock API. When you activate this tool, your browser sends an explicit signal to the OS requesting that the display remains active. This is entirely sandboxed and safe—the absolute second you close this browser tab, navigate away, or your battery hits a critical threshold, the lock is automatically released, and your system's normal power-saving schedule resumes immediately.

Power-User Scenarios

  • The Kitchen Display: Prop your iPad up and keep your baking recipes visible indefinitely without tapping the screen with dirty fingers.
  • Livestream Command Centers: Put this on a secondary monitor while maintaining OBS or Twitch chat; guarantee the screen won't sleep if you don't touch the mouse for 15 minutes.
  • Exam Proctoring: Teachers can project a countdown timer over this tool to ensure the projector doesn't shut off in the middle of a quiet testing session.

Key features

  • One-tap wake lock: Request a screen wake lock in supported browsers (Chrome, Edge, Android). Keeps the display awake until you release it.
  • Auto resume: If the browser suspends the wake lock when you switch tabs, the tool tries to reapply it when you return.
  • Fallback guidance: Provides quick tips for iOS and other unsupported browsers so you can manually keep the display awake.

Frequently asked questions

Which browsers support wake lock?

Chrome, Edge, and most Chromium-based mobile browsers support the Screen Wake Lock API. Safari currently does not.

Does it work on mobile?

Yes, it works on Android devices using Chrome or other Chromium browsers. iOS (Safari) support is currently limited by Apple's restrictions.

Do I need to keep the tab open?

Yes. The Wake Lock API only functions when the tab is active or at least visible. Minimizing the browser or switching tabs may release the lock to save battery.

What happens if my browser blocks it?

You will see instructions for keeping the screen on manually—such as disabling auto-lock or using Guided Access on iOS.

Is it safe to keep on all the time?

Yes, but it may drain your battery faster. Turn it off when you no longer need the screen awake.
