Share a tab, not a window: how to do it in Meet, Zoom and Teams

What a tab share hides, and why it beats a window

A tab share transmits one browser tab's rendered page and nothing else, which removes the most common screen-share leaks in a single decision. Compared with sharing a browser window, a tab share keeps all of this off the feed:

• The address bar, along with every URL you type and the autocomplete dropdown your history builds under it.
• The tab strip, where every other tab's title and favicon would otherwise be readable by the whole room.
• The bookmarks bar, folder names and all.
• Notification toasts, which are drawn by the OS outside the tab and so never enter the capture.
• Every other window, your desktop and your taskbar.

A window share of the browser hides only the last item on that list. Everything else, from the tab strip to the address bar, sits inside the browser window and gets shared with it. If what you are presenting is a web page, share the tab. Here is where the option lives in each of the three big meeting apps.

How to share a tab in Google Meet

Google Meet has tab sharing built in: click Present now in the meeting controls and choose A tab.

1. In the meeting controls, click Present now.
2. Choose A tab (the other options are A window and Your entire screen).
3. Pick the tab you want from the list and click Share.
4. When you present a Chrome tab, Meet shares that tab's audio by default, so a video playing in the tab is heard without touching your mic or system audio.
5. To present a different tab, switch to it and click Share this tab instead on the banner Chrome shows at the top. The share never moves without that click.

Meet is the simplest of the three because it always runs in the browser, so the tab option is present for everyone rather than hidden behind a web version.

How to share a tab in Zoom

The Zoom desktop client cannot share a single browser tab: its share sheet offers entire screens and application windows, so tab sharing means using the Zoom web app in your browser instead.

1. Open the meeting in the Zoom web app in your browser rather than the desktop client.
2. Click Share Screen in the meeting toolbar.
3. The browser's own picker opens. Zoom's documentation describes the choice exactly: select the browser tab, app window, or entire desktop. In Chrome, switch to the tab list and pick your tab.
4. Turn on Also share tab audio if the room should hear the tab.
5. Click Share.

If you have to stay in the desktop client, two fallbacks narrow the exposure. You can share the browser window and accept that the tab strip and address bar ride along, masking the titles with Tab Privacy first. Or you can use Advanced, then Share a Portion of Screen, and drag the capture rectangle so it covers the page area only, cropping the browser chrome out of the frame. The rectangle is pinned to your screen, not to the browser, so anything you drag into that region is shared too.

How to share a tab in Microsoft Teams

Microsoft Teams shares a tab only when you run Teams in the browser: the desktop app's share tray offers screens and windows (plus modes like PowerPoint Live), and Microsoft supports sharing from Teams on the web in Google Chrome and the latest Edge, with Linux not currently supported.

1. Open Teams in Chrome or Edge and join the meeting there.
2. Click Share in the meeting controls.
3. The browser's picker appears, the same one Meet and the Zoom web app use. Choose the tab list, pick your tab, and share. The tab-audio toggle is available here too.

A warning about the desktop app's Include sound toggle, in Microsoft's own words: all sound from your computer, including notifications, will be audible in the meeting. If you turn it on, pause notifications first.

For slide decks in Teams, PowerPoint Live presents the file itself without capturing any screen, window or tab at all.

Tab vs window vs entire screen: what each mode exposes

Each step from tab to window to entire screen adds more of your machine to the feed. The table assumes the window in the middle column is a browser window.

Swipe sideways to see all three modes.

What a tab share cannot hide: the page itself

Every mode, tab sharing included, shows viewers the entire contents of the page you present: the revenue figures on the dashboard, the customer names in the table behind your demo, the API key sitting in the settings page you opened for two seconds. Choosing the right mode controls what surrounds the page. It does nothing about what is in it.

Blurr.ing handles that part. Before you share, frost the sensitive parts in the page itself: draw a box over a region, click an element (hold Alt and scroll to grow the selection from a word to a card to a table), or select a run of text. Manual blurs are free, unlimited, on every site, with no account. A free blur clears when the page refreshes; Premium ($5 a month, $29 a year, or $39 once) saves them and restores them before the page first paints, and adds Auto Blur for whole categories (images, videos, SVG icons, ads) plus Blur Text rules with 34 presets and AND/OR/NOT logic for things like emails, card numbers and keys.

It works on web pages in Chrome, Edge, Brave and Arc, reaches same-origin iframes at any depth and open shadow DOM, and can blur a cross-origin iframe only as one whole frame. It cannot touch anything outside the browser page. The step-by-step basics are in how to blur part of a web page.

When you genuinely need a window or the whole screen

Tab sharing stops making sense the moment the demo leaves the browser: native app walkthroughs, IDE sessions, and flows that hop between applications need a window or an entire screen. In those cases, combine these:

• Mask the tab strip. If a browser window has to be on screen, Tab Privacy replaces every tab title and favicon with one of 17 neutral disguise styles. The free plan covers three activations.
• Silence the toasts. OS-level Do Not Disturb (Focus on macOS, Do not disturb on Windows), plus pauses in the chat apps themselves. Microsoft's own sharing doc tells presenters to enable Do not Disturb so others cannot see notifications.
• Close what you can. A window share hides other windows, but an entire-screen share hides nothing, and a closed window leaks in neither.
• Use the emptier monitor. On a multi-screen rig, share the screen that holds only the demo and park everything else on the other one.
• Blur what stays. Whatever sensitive content remains inside the shared apps' pages, frost it before the call.

The one-minute version of all of the above, in checkbox form, is the screen-share privacy checklist.
