How to Cast a Chrome Tab to a TV (No Extension Needed)

How do you cast a Chrome tab to a TV?

Casting a tab is a built-in Chrome feature — no chrome extension chromecast tool is required for the basic job of mirroring a tab to your TV.

1. Click More (the three-dot menu) in the top-right of Chrome.
2. Go to Save and Share, then Cast....
3. In the panel that opens, choose your TV or Chromecast device from the list of sources.
4. Chrome starts casting the current tab to that screen; a Casting icon appears in the address bar so you can stop anytime.

This mirrors whatever is on the tab, including video sites, dashboards, slideshows, and anything else you'd normally watch or present from your computer.

How do you add a permanent Cast button to the Chrome toolbar?

You don't need it pinned to cast, but it saves you a trip through the menu every time.

1. In Chrome, click More, then Save and Share, then Cast... — the Cast button appears temporarily in your toolbar.
2. Right-click that temporary Cast button.
3. Choose Always show icon.
4. The Cast button now stays pinned in your toolbar for one-click access any time.

What do you need before you can cast a tab to a TV?

You need a Chromecast-capable TV or streaming device that's already set up, and it needs to share the same Wi-Fi network as your computer.

• The TV, or a Chromecast/Google TV device plugged into it, is already set up once through the Google Home app.
• Your computer and that device are on the same Wi-Fi network.
• Chrome is up to date, since older versions can lose the ability to discover cast devices.
• You're not on a guest or isolated Wi-Fi network — many of those block devices from finding each other even when both are technically connected.

Do you still need a separate Chrome extension to cast?

No. Casting a tab is a native, built-in Chrome feature, not something you install separately.

Google previously offered a standalone Google Cast extension years ago, but that functionality moved into Chrome itself, accessed through More > Save and Share > Cast.... If you're seeing search results or forum posts asking 'where's my Cast extension,' it's almost always someone remembering that older, separate version, not a sign that casting currently requires an install.

Can an extension cast just a video instead of the whole tab?

Yes, some extensions target a specific video file on a page rather than mirroring the entire tab, though this only works for public, unprotected video files.

CastBuddy is one example: it finds direct video links on the page you're viewing and opens a Chrome side panel where you can play them on your Chromecast or Google TV device. It works best with publicly accessible HTTPS videos in widely supported formats, especially MP4 with H.264 video and AAC audio.

It doesn't work with everything, though. Videos protected by DRM, temporary blob links, or URLs that require your browser cookies or account login typically won't play, because the cast device needs to access the video directly, and CastBuddy doesn't download videos or bypass any site's protections.

Why is there no sound, or bad audio, when you cast a Chrome tab?

Usually it's the tab's own volume, a network hiccup, or the TV's separate volume setting, rather than the cast connection itself.

• Your TV or soundbar volume is a separate control from your computer's volume — check both.
• Casting sends whatever audio the tab is playing; if the tab is muted, no audio reaches the TV either (see our guide on how to mute a tab in Chrome for the reverse situation).
• Network congestion between your computer, router, and the Chromecast device can cause audio to lag slightly behind video during a live tab cast.
• Audio that's already quiet at the source stays quiet once cast, since Chrome casts the tab's existing audio level rather than boosting it.

Why did casting suddenly stop working, or the option disappeared?

Most of the time it's a network mismatch, an outdated Chrome, or the icon simply being hidden rather than the feature being gone.

• Chrome and the TV or Chromecast device are no longer on the same Wi-Fi network, including guest networks that isolate devices from each other.
• Chrome needs an update — an outdated version can lose device discovery entirely.
• The Cast icon isn't pinned, so the option looks like it vanished when it's actually just tucked under More > Save and Share.
• The TV or Chromecast device needs a restart, which clears most temporary discovery glitches.
• A single tab keeps stalling mid-cast (a live stream or dashboard tab); reloading it restarts the connection instead of restarting the whole cast, and Tab Reloader or Tab Auto Refresh can automate that reload on a timer for a tab you cast continuously, like a slideshow or dashboard.

Can you cast from Chrome on Android or iPhone?

On Android, yes, using Chrome's own menu; on iPhone or iPad, casting a tab directly isn't part of Chrome the same way.

On Android, Chrome's app menu (the three dots) includes its own Cast... option that mirrors a tab to a nearby TV or Chromecast device once both are on the same Wi-Fi network, the same way desktop does.

On iOS, Chrome doesn't offer the same tab-casting menu item. Casting from an iPhone or iPad more commonly goes through an individual app's own cast button, such as YouTube's or a streaming service's, or through the Google Home app, rather than mirroring a Chrome tab directly.

Which extensions actually help with casting or the audio problems around it?

Since casting itself is built into Chrome, the extensions worth adding here solve specific edge cases: quiet audio and a stalling stream.
