Does this change my Mac Energy Saver settings?

No. Your Energy Saver and power settings stay exactly the same. This tool keeps your Mac screen awake without changing your device settings.

Does it stop my Mac from locking?

It helps keep your Mac screen on and prevents screen sleep while the timer is running. On some devices, security policies or system restrictions may still lock the Mac automatically.

Can it keep my Mac awake?

Yes. It helps keep your Mac awake so work apps, messaging platforms, remote desktop sessions, dashboards, and similar services are less likely to become inactive because the screen turned off or the computer entered sleep mode.

Does it work on MacBook and desktop Macs?

Yes. It works on MacBook, iMac, Mac mini, Mac Studio, and other modern Macs in Safari, Chrome, Firefox, and other supported browsers.

Do I need to install anything?

No. Everything runs directly in your Mac browser.

What happens if I close the page?

The Screen Wake Lock ends when the page is closed.

Keep Your Mac Screen On Without Installing Anything

Keep Screen On is a free browser tool that keeps your Mac screen on and prevents it from turning off while this page remains open. Choose a time limit or No Limit, press Start, and keep your Mac display awake without changing Energy Saver or other macOS settings.

The tool uses the Screen Wake Lock feature supported by Safari, Chrome, and other modern browsers on macOS to prevent screen dimming, screen sleep, and automatic locking while the timer is running. It does not change your Mac settings, and there is nothing to download or install.

It works on MacBook, iMac, Mac mini, and Mac Studio in Safari, Chrome, Firefox, and other supported browsers. Whether you need to keep your Mac display on for a few minutes or keep your computer awake for hours, you can start the timer and let it run until you're finished.

Why keep your Mac screen awake?

The most common reason to keep your Mac screen on is to stay marked as online or active in work apps, messaging platforms, remote desktop sessions, and social media without your Mac entering sleep mode or locking while you're away.

It is also useful while downloads, uploads, backups, updates, and other long-running tasks are in progress on your Mac. Keeping your display awake helps prevent screen timeout, screen dimming, and interruptions caused by sleep mode.

You can also use it whenever you want to keep your Mac display on, avoid repeated password prompts, prevent screen sleep during presentations, or simply stop your computer from sleeping for a while without changing your normal Energy Saver settings.

Keep screen on for your device

Open a device-specific page for iPhone, Android, Mac, Windows, or Linux — same free browser wake lock, no signup.

How it works

Choose No Limit, Custom, or one of the available time options.
Press Start.
Leave this page open while the timer is running.

Frequently asked questions

Mac display reference

Expand each topic for macOS-specific notes on keeping the screen awake from the browser.

Energy Saver vs browser wake lock

Energy Saver and Battery settings control how macOS blanks the display system-wide. Keep Screen On only holds a wake lock while this Safari or Chrome tab stays open — your Energy Saver preferences are left alone.

MacBook, iMac, Mac mini, Mac Studio

The same page works across Apple silicon and Intel Macs in supported browsers. Start Always On or a timed session when you need the display to stay lit for demos, downloads, or remote work.

Password prompts and sleep

Preventing display sleep reduces repeated password prompts caused by the screen locking while a long task runs. Closing the tab or pressing Stop ends the wake lock immediately.

When macOS may still sleep

Managed Macs with forced lock policies, low-power modes, or closed-lid laptop behavior can still override browser wake lock. For everyday use on a personal Mac, the in-browser session is usually enough.
