How to Go Full Screen on Any Browser, Windows, or Mac
Every major browser and operating system has a full screen shortcut. Here they all are in one place, plus what to do when full screen will not activate.
Full screen mode hides your browser’s toolbar, tabs, and taskbar so a page or video fills the entire display. Every major browser and operating system supports it, but the shortcut and behavior differ by platform. This guide covers every combination: Windows, Mac, Chromebook, and mobile, plus what to do when full screen mode will not activate.
Full screen shortcuts at a glance
| Platform | Shortcut | Exit |
|---|---|---|
| Windows (Chrome, Firefox, Edge) | F11 | F11 or Esc |
| Mac (Safari, Chrome, Firefox) | Control + Command + F | Control + Command + F |
| Chromebook | F11 or dedicated key | Same key again |
| Android Chrome | In-page full screen control | Tap the screen or press back |
| iOS Safari | In-page or in-video icon | Tap the screen or the exit icon |
Chrome, Firefox, Edge
The shortcut
Press F11 once to enter, and again (or press Esc) to exit. Some laptop keyboards require holding Fn together with F11 if the F-keys default to media controls.
Mouse-based alternative
Chrome: click the three dots, then look for the full screen icon near the zoom controls. Firefox: open the hamburger menu and select full screen. Edge: use the three-dot menu and look for “Zoom,” which has a full screen toggle.
Safari, Chrome, Firefox
The shortcut
Click the green button in the top-left corner, or press Control + Command + F. The menu bar and dock hide automatically.
Switching without exiting
Full screen mode creates a separate virtual desktop (Space) for that window. Swipe left or right with three fingers on the trackpad to move between the full screen app and other open windows without exiting.
Chromebook and mobile
Chromebook
Use F11 or the dedicated full screen key on the top row, usually a rectangle icon with two arrows. Press it once to enter and again to exit.
Android Chrome
Tap a full screen button inside a video player or web app. The address bar and navigation buttons hide, the same as desktop.
iOS Safari
Support is more limited than desktop. iOS Safari restricts full screen mode for regular web pages more heavily, though video players still support full screen playback through their own controls. Look specifically for a full screen icon inside the video or app itself, since browser chrome does not always hide through a generic request on a regular page.
Why won't a page go full screen?
No prior interaction
Browsers require a direct click before allowing a page to request full screen automatically. Click the full screen button directly rather than expecting it on load.
An extension is interfering
Ad blockers and privacy extensions occasionally block the Fullscreen API. Open a private window, which disables most extensions by default, to test.
The site restricts it
A small number of sites intentionally disable full screen requests. This is a site-level decision, not fixable from your end.
An outdated browser
Very old browser versions may not fully support the modern Fullscreen API. Updating resolves most compatibility issues.
Multiple monitor confusion
Full screen mode applies to whichever monitor currently has the active window. Drag the window to the intended monitor first, then trigger full screen.
Video full screen vs. whole-page full screen
Presentations, screen shares, and gaming
Presentations and demos
Full screen mode removes distracting browser chrome and bookmarks during a screen share or in front of an audience. If presenting through a projector, confirm which display is active before triggering full screen.
Video conferencing screen shares
Full screen mode on the shared tab, not just the call window, gives viewers a cleaner view without your bookmarks bar visible. Trigger it before starting the share.
Browser-based gaming
Browser games frequently request full screen automatically when you click to play. If the prompt does not respond, the same troubleshooting steps above apply.
Google Slides and PowerPoint Online
Both trigger full screen automatically through their own “Present” mode. If a browser toolbar still shows, press F11 in addition to starting the presentation.
Common mistakes
- Expecting F11 to work identically everywhere. The shortcut is consistent on Windows, but Mac uses a different key combination entirely.
- Forgetting that Esc is the universal exit key across nearly all full screen implementations, including video players.
- Assuming a stuck full screen state means the browser has frozen. Try Esc first before force-closing anything.
The standard behind full screen mode
Full screen mode in modern browsers is built on the Fullscreen API, a web standard documented by MDN Web Docs that lets a page request exclusive use of the display through the browser, without any plugin or extension. Try it now: the white screen tool and color screen test both use the exact shortcuts covered in this guide.

Frequently asked questions
What is the keyboard shortcut for full screen?
On Windows, press F11 in most browsers. On Mac, press Control + Command + F, or click the green full screen button in the top-left corner of the window.
Why won't a website go full screen?
Some browsers block full screen mode until you interact with the page first, such as clicking a button. Browser extensions, especially ad blockers or privacy tools, can also interfere with the Fullscreen API. Try clicking directly on the page before triggering full screen, or briefly disable extensions to test.
How do I exit full screen?
Press Escape on any browser or operating system. On Mac, you can also click the green button again or move your cursor to the top of the screen to reveal the exit control.
Does full screen mode work the same on mobile?
Mobile browsers support a more limited version of full screen. iOS Safari in particular restricts full screen for regular web pages; Android Chrome generally supports it well for video and the Fullscreen API.
