WebRTC Leak Test
Instantly check if your browser exposes your real IP address through WebRTC. This technology, designed for real-time communication, can bypass VPNs and proxies, revealing your true identity.
Your browser is not exposing additional IP addresses through WebRTC. Your privacy appears intact.
What Is WebRTC Technology?
WebRTC (Web Real-Time Communication) is an open-source technology that enables direct peer-to-peer communication between browsers without requiring plugins or third-party software. It powers video calls, voice chats, file sharing, and live streaming directly in your browser.
Major platforms like Google Meet, Discord, and Twitch rely on WebRTC for low-latency communication. While incredibly useful, this technology requires access to your network information, which can inadvertently expose your IP address.
What Is a WebRTC Leak?
A WebRTC leak occurs when your browser reveals your actual IP address through WebRTC connections, even when you're using a VPN or proxy. This happens because WebRTC uses the STUN/TURN protocol to discover your IP, which can bypass your VPN tunnel.
Unlike other types of leaks, WebRTC leaks happen at the browser level and are independent of your network configuration. As long as WebRTC is enabled and a website makes the right API calls, your real IP can be exposed.
Risks of a WebRTC Leak
How Our WebRTC Leak Test Works
Create Connection
We initialize a WebRTC peer connection using standard STUN servers, simulating a real-world WebRTC scenario.
Gather Candidates
The browser generates ICE candidates containing network information, including potential IP addresses.
Analyze Results
We parse each candidate to extract IP addresses and classify them as local, public IPv4, or IPv6.
Report Findings
Results are displayed instantly showing which IPs were discovered and whether a leak exists.
How to Verify a WebRTC Leak
Disconnect from your VPN and note your real IP address
Connect to your VPN and verify you have a new IP
Run this WebRTC leak test while connected to VPN
If your original IP appears in results — you have a leak
How to Fix a WebRTC Leak
Disable WebRTC in Browser
Firefox: Type about:config in the address bar and set media.peerconnection.enabled to false. This completely disables WebRTC.
Chrome: Chrome does not allow fully disabling WebRTC through settings. Use a browser extension or a VPN.
Use a Reliable VPN
Choose a VPN with built-in WebRTC leak protection. Services like ProtonVPN offer this feature and actively block WebRTC from exposing your real IP.
Install Browser Extensions
If you prefer not to change browser settings manually, you can use ready-made extensions: WebRTC Control — it works in both Chrome and Firefox and lets you quickly toggle WebRTC on and off.
Frequently Asked Questions
A WebRTC leak exposes your IP address through browser-level APIs, while a DNS leak reveals the DNS servers you're using. WebRTC leaks are unique because they can bypass VPN tunnels by making direct STUN requests, whereas DNS leaks typically stem from misconfigured network settings.
Yes. Chromium-based browsers (Chrome, Edge, Brave) and Firefox support WebRTC by default, making them more susceptible. Safari handles WebRTC more cautiously, blocking camera and microphone access by default. Each browser requires different steps to mitigate leaks.
Adjusting browser settings can reduce risk, but for comprehensive protection it's recommended to combine browser configuration with a VPN that blocks WebRTC leaks and dedicated browser extensions.
Yes. Our WebRTC leak test runs entirely in your browser. No data is sent to any server. The IP addresses detected are only shown to you and are not stored or logged anywhere.
Proxies can mask your IP for regular web traffic, but WebRTC operates at a lower level and can bypass proxy settings entirely. To fully protect against WebRTC leaks, you should disable WebRTC in your browser or use a VPN with leak protection.
Yes. Mobile browsers like Chrome and Firefox on Android support WebRTC and can leak your real IP address, even when using a VPN. On iOS, Safari has more restrictive WebRTC handling, but it's still recommended to check for leaks.
Disabling WebRTC may affect video and voice calls in the browser (Google Meet, Discord, Zoom web client). If you need these services, consider using a VPN with WebRTC leak protection instead of disabling it entirely.
No. Incognito (private) mode does not disable WebRTC. Your real IP address can still be exposed through STUN requests even in private browsing. You need to specifically disable WebRTC or use a VPN.
It's recommended to check after every browser update, after installing new extensions, after changing VPN settings, or when switching to a new browser. Browser updates can sometimes reset your privacy settings.
Yes, websites can detect that WebRTC is unavailable, but they cannot determine why. This is not a privacy concern — many users have WebRTC disabled, and websites simply fall back to alternative methods for communication.
