What Is a WebRTC Leak?

WebRTC (Web Real-Time Communication) is a browser technology that enables peer-to-peer video calls, voice chat, and file sharing without plugins. To establish direct connections, WebRTC uses STUN servers to discover your IP addresses — including both your public IP and local network IPs. This happens at the browser level, completely bypassing your VPN tunnel.

Even with a VPN active, a malicious website can use JavaScript to trigger WebRTC and discover your real IP address through ICE (Interactive Connectivity Establishment) candidates. This is one of the most common VPN leaks, and many users are unaware their browser is exposing their identity.

How to Disable WebRTC

In Firefox, type about:config in the address bar and set media.peerconnection.enabled to false. In Chrome, install an extension like "WebRTC Leak Prevent" since Chrome doesn't allow disabling WebRTC natively. Brave has a built-in option under Settings > Privacy > WebRTC IP Handling Policy. For complete protection, use a VPN with built-in WebRTC leak prevention.

FAQ

What is WebRTC?

WebRTC (Web Real-Time Communication) is a browser technology for peer-to-peer communication including video calls, voice chat, and file sharing. It's built into all major browsers and works without plugins.

How does a WebRTC leak expose my IP?

WebRTC uses STUN servers to discover your network interfaces and IP addresses. This process happens at the browser level and can bypass your VPN, revealing your real public IP and local network addresses to websites.

Can a VPN prevent WebRTC leaks?

Some VPNs include WebRTC leak protection that blocks or restricts WebRTC's ability to discover your real IP. However, not all VPNs offer this — which is why testing is important.

Does disabling WebRTC break anything?

Disabling WebRTC will prevent browser-based video and voice calls (like Google Meet, Discord in-browser, Facebook Messenger calls). If you use these services, consider using a VPN with WebRTC leak protection instead of disabling it entirely.
