How to Share Your Screen in a Browser Video Call (No App Needed)
Step-by-step guide to sharing your screen during a video call using just your browser. Works on Chrome, Firefox, Edge, and Safari — no downloads required.
Screen sharing used to require an app. A plugin, a download, a permissions dialog that went three levels deep. That's changed.
Modern browsers can share your screen natively — no extensions, no installs. If you're on Chrome, Firefox, Edge, or Safari, you can share your screen right now using any browser-based video calling tool that supports it.
Here's how it works and how to do it on each browser.
What Is Browser Screen Sharing
The technical name is getDisplayMedia — a browser API that lets a web page request access to your screen, a specific window, or a browser tab. When a video call tool asks you to share your screen, that's what's happening under the hood.
It's part of the same WebRTC family of browser features that enables camera and microphone access during video calls. The browser asks for your permission, you choose what to share, and a video stream of that content goes to the other participants.
Importantly, the browser is always in control. The website can only capture what you explicitly select. You can stop sharing at any moment by clicking the stop button — in the site, or in the browser's toolbar indicator that appears during screen sharing.
You don't need an app for this to work. The browser does all of it.
Step-by-Step: How to Share Your Screen by Browser
Chrome
Chrome has the most complete screen sharing support of any browser.
Chrome will show a small indicator at the bottom of your screen while you're sharing. To stop, click Stop sharing there or in the call interface.
Tip: If you want to share audio along with a tab (for example, playing a video), select Chrome Tab, check the Share tab audio checkbox, then click Share.Firefox
Firefox screen sharing works the same way conceptually, with a slightly different dialog.
Firefox shows a persistent indicator in the browser toolbar (a small screen icon) while you're sharing. Click it to see sharing status or stop.
Note: Firefox does not currently support tab-only sharing with audio the way Chrome does. If audio from a shared tab matters, Chrome is the better choice.Edge
Edge is built on Chromium, so the screen sharing experience is nearly identical to Chrome.
Edge has the same tab audio sharing option as Chrome. The toolbar indicator works the same way.
Safari
Safari added getDisplayMedia support in version 15.4 (released 2022). It works, but with some differences from Chrome and Firefox.
- Safari only supports sharing entire windows or screens, not individual browser tabs.
- Tab audio sharing is not supported.
- On older macOS versions (pre-Monterey), you may also need to grant Screen Recording permission at the OS level (see the macOS section below).
What You Can Share
Most browsers offer three options when you start screen sharing. Understanding them helps you choose the right one.
Entire Screen shares everything visible on your monitor. The other participants see everything — every window, notification, and cursor movement. Use this when you're presenting and need to switch between applications freely. A specific window shares just one application window. Other windows stay private. Good for sharing a document, a design tool, or a presentation while keeping everything else off-screen. If you minimize the shared window, the stream will typically show a blank or frozen frame. A browser tab (Chrome/Edge) shares a single tab. Nothing else is visible. This is the most private option and the only one that supports sharing audio from the tab itself. Use it when playing a video or audio clip as part of your call.For most work calls, window sharing strikes the right balance — you control exactly what's visible without needing to manage your entire desktop.
Common Issues and Fixes
The screen share button is grayed out or missing
This usually means one of two things: the browser doesn't support getDisplayMedia (update your browser), or the site isn't served over HTTPS. Browser screen sharing requires a secure connection. If the URL starts with http:// rather than https://, the feature won't be available.
Permission denied or nothing happens when you click share
Check browser-level permissions. In Chrome, click the lock icon in the address bar and look for media or screen permissions. In Firefox, the same icon shows site-specific permissions. If screen sharing was previously denied, you may need to reset it there.
macOS: "Screen Recording" permission required
On macOS (Catalina and later), apps — including browsers — need explicit Screen Recording permission in System Preferences before they can capture your screen.
Go to: System Settings > Privacy & Security > Screen Recording
Make sure your browser (Chrome, Firefox, Edge, or Safari) has a checkmark. If it's not listed, you may need to add it or trigger it by attempting a screen share, which will prompt the system to ask for permission.
After granting permission, restart the browser completely. The permission doesn't take effect until the browser relaunches.
Screen share freezes or quality is poor
Screen sharing adds to your bandwidth usage. If your upload speed is limited, both your camera feed and screen share will compete for the same resource. Lowering the video quality of your camera feed (if the platform allows it) can help. Closing other background uploads also frees up headroom.

Tips for Better Screen Sharing
A few habits that make screen shares clearer and more professional:
- Close notifications before sharing. Email popups, Slack messages, and system alerts will appear in the share. On macOS, enable Do Not Disturb before presenting. On Windows, use Focus Assist.
- Use tab sharing when playing video or audio. Window and full-screen sharing doesn't capture browser audio. Only Chrome and Edge tab sharing does.
- Increase your browser zoom level before sharing a tab. Small text becomes hard to read when compressed into a video stream. 110–125% zoom makes things noticeably clearer.
- Share a specific window, not your whole screen, when your desktop has anything you'd rather keep private.
- Check what the other person actually sees. Ask them to confirm the share looks right before diving in. Sometimes the wrong window gets selected.
Screen Sharing on Mobile
Android
Screen sharing from a browser on Android is limited. Chrome for Android does not support getDisplayMedia in the same way desktop Chrome does. Some platforms have workarounds, but browser-based screen sharing on Android is not reliable as of 2026. If you need to share your screen from an Android device, a native app is the more dependable route.
iOS (iPhone and iPad)
Safari on iOS 15.4+ has partial getDisplayMedia support, but it's more limited than desktop Safari. Screen sharing in browser-based video calls on iOS varies significantly by platform. Some tools work; many don't. Apple's ReplayKit framework underpins iOS screen recording, and not all browser implementations hook into it cleanly.
For reliable mobile screen sharing, native apps currently handle it more consistently than browser-based options on both major mobile platforms.
Try It Now
If you want to test browser screen sharing right now, videocalling.app supports it without any account or installation. Start a room, invite someone, and click the screen share button. It uses the same getDisplayMedia API described in this guide — you'll see exactly how the browser permission dialog works.
It's a useful way to test your setup before a meeting where screen sharing actually matters.
