How to Share Your Screen in a WebRTC 1:1 Call
Available in other languages
WebRTC screen sharing makes online calls more useful because you can show what is on your screen in real time instead of describing it. For support, demos, onboarding, or troubleshooting, this removes delay and confusion.
In JustCall, screen sharing is part of the same browser-based 1:1 call. Your screen replaces camera video, your mic can continue, and when you stop sharing, your camera returns automatically.
This guide explains how to share screen in a WebRTC call and what to expect from browser screen sharing in a P2P-friendly 1:1 flow.
How to share your screen in a WebRTC 1:1 call
01
Start a 1:1 browser call
Open JustCall in your browser, create or join a room, and start the live WebRTC call.
02
Click Share screen
Use the in-call control panel to start screen sharing from the same call interface.
03
Choose what to share
In the browser picker, select a tab, app window, or full display and confirm.
04
Stop sharing when done
When you stop sharing, JustCall restores your camera video automatically in the current call.
Why this is useful for 1:1 calls
Browser-based flow
You can share your screen in a WebRTC call without installing a separate app.
Mic stays active
Your microphone can continue while your screen replaces camera video.
Fast visual context
Screen sharing is ideal for support, demos, onboarding, and live walkthroughs.
Camera comes back
Stopping screen sharing returns the outgoing video feed to your camera.
P2P screen sharing in a browser-based call
The screen-sharing experience in JustCall is designed for lightweight 1:1 calls where both participants stay in one browser session. That is why it feels fast for live collaboration and quick decision loops.
It is accurate to call this a P2P-friendly WebRTC flow. At the same time, media paths can vary based on browser and network conditions, so it is better to focus on user-visible behavior: quick setup, live screen video, live mic audio, and automatic camera restore.
