WebRTC Leak Test
Check if your browser is exposing your real IP address through WebRTC, even when using a VPN.
What is WebRTC?
WebRTC (Web Real-Time Communication) is a browser technology that enables real-time voice and video communication directly between browsers without needing plugins.
It powers features like video calls, screen sharing, and file transfers in web applications like Google Meet, Discord, and many others.
Why WebRTC Leaks Matter
WebRTC requires your browser to discover its IP addresses to establish peer-to-peer connections. This process can bypass VPN tunnels and reveal your real IP address.
Even if you're using a VPN to hide your IP, websites can use WebRTC to discover your actual IP address, compromising your privacy.
How to Prevent WebRTC Leaks
Use a VPN
Choose a VPN with built-in WebRTC leak protection. Premium VPNs often include this feature.
Browser Settings
Disable or limit WebRTC in your browser settings. Chrome and Firefox have built-in options.
Browser Extensions
Install extensions like uBlock Origin or WebRTC Leak Prevent to block WebRTC requests.
Frequently Asked Questions
Does disabling WebRTC break websites?
Disabling WebRTC may affect video calling apps and some real-time features. If you use services like Google Meet or Discord in your browser, you may want to use a VPN with WebRTC protection instead of disabling it entirely.
My VPN says it has WebRTC protection. Why am I still leaking?
Some VPNs only protect against WebRTC leaks in their desktop apps, not browser extensions. Additionally, IPv6 leaks through WebRTC are often not covered. Make sure your VPN settings have WebRTC protection enabled.
What's the difference between local and public IP leaks?
Public IP leaks expose your real internet-facing IP address and are critical privacy concerns. Local IP leaks expose your internal network IP (like 192.168.x.x) which reveals less but can still provide information about your network setup.
