Free WebRTC Leak Test Tool – Check If Your VPN Is Really Protecting You
Using a VPN to hide your real IP address? A WebRTC leak can silently expose your true location even when your VPN is connected. Our free, instant WebRTC leak test tool detects this common vulnerability in seconds – no signup required.
What Is a WebRTC Leak?
WebRTC (Web Real-Time Communication) is a browser technology that enables real-time video calls, voice chat, and peer-to-peer data sharing. To work properly, it queries STUN servers for your public IP addresses – often bypassing your VPN tunnel. This creates a WebRTC IP leak that reveals your real ISP-provided IP address.
- Exposes your actual location and identity to websites
- Undermines your VPN’s anonymity protection
- Common in Chrome, Firefox, Edge, Brave, and Opera
- Can occur even when your VPN status shows “connected”
Why Use Our WebRTC Leak Test Tool?
Many basic IP checkers miss WebRTC leaks entirely. Our advanced WebRTC leak test tool specifically probes the WebRTC channel, comparing your public VPN IP against any addresses discovered via STUN requests. Results are clear: secure or leaked – with maps, flags, and detailed diagnostics.
Signs You Might Have a WebRTC Leak
Common indicators include:
- Your real IP appearing on leak test sites while VPN is active
- Geolocation showing your home location instead of VPN server
- Inconsistent IP results across different test tools
