WebRTC Leak Checker

Protect your privacy by detecting if your browser is leaking your real IP address through WebRTC

Secure Your Online Identity

WebRTC leaks can expose your real IP address even when using a VPN. Our advanced tool helps you identify and fix these privacy vulnerabilities in seconds.

What is WebRTC Leak Testing?

WebRTC (Web Real-Time Communication) is a powerful technology that enables real-time communication directly between browsers without requiring plugins. It powers video calls, file sharing, and chat applications across the web. However, this same technology can inadvertently expose your true IP address, even when you're using a VPN or proxy service for privacy protection.

Our WebRTC Leak Checker tool examines your browser's WebRTC implementation to determine if it's leaking your private IP addresses. This is crucial for maintaining anonymity online, especially when using privacy tools like VPNs or when accessing geo-restricted content.

Why WebRTC Leaks Are Dangerous

WebRTC leaks pose significant privacy and security risks for various online activities:

  • VPN Circumvention: WebRTC can bypass your VPN tunnel, revealing your actual IP address and location.
  • Identity Exposure: Your real IP address can be used to identify you, track your online activities, or approximate your physical location.
  • Geo-restriction Bypass Detection: Streaming services and websites can detect that you're using a VPN if your WebRTC is leaking.
  • Network Information Disclosure: WebRTC can expose details about your internal network configuration.
  • Targeted Attacks: Malicious actors can use leaked IP information for targeted attacks or social engineering.

How to Fix WebRTC Leaks

Chrome
Firefox
Edge
Safari
Opera

Google Chrome requires extensions to block WebRTC leaks:

  1. Install the WebRTC Leak Prevent or WebRTC Control extension from the Chrome Web Store.
  2. Click on the extension icon in your browser toolbar.
  3. Select "Disable WebRTC" or "Use the proxy settings to prevent WebRTC leaks."
  4. Refresh your browser and test again to confirm the leak is fixed.

Firefox has built-in settings to prevent WebRTC leaks:

  1. Type about:config in your address bar and press Enter.
  2. Accept the warning message that appears.
  3. Search for media.peerconnection.enabled.
  4. Double-click the preference to set its value to false.
  5. Alternatively, set media.peerconnection.ice.default_address_only to true to only use your public IP.

Microsoft Edge (Chromium-based) requires extensions:

  1. Install the WebRTC Leak Prevent extension from the Edge Add-ons store.
  2. Click on the extension icon in your browser toolbar.
  3. Select "Disable WebRTC" or "Use the proxy settings to prevent WebRTC leaks."
  4. Restart your browser and test again.

Safari has limited WebRTC leak protection options:

  1. Open Safari Preferences.
  2. Go to the Privacy tab.
  3. Uncheck "Allow websites to check if Apple Pay is set up."
  4. For better protection, consider using a VPN with WebRTC leak protection.

Opera requires extensions to block WebRTC leaks:

  1. Install the WebRTC Leak Prevent extension from the Opera add-ons store.
  2. Click on the extension icon in your browser toolbar.
  3. Select "Disable WebRTC" or "Use the proxy settings to prevent WebRTC leaks."

Frequently Asked Questions

What exactly is WebRTC?

WebRTC (Web Real-Time Communication) is an open-source project that provides web browsers and mobile applications with real-time communication capabilities through simple APIs. It allows audio and video communication to work inside web pages by allowing direct peer-to-peer communication, eliminating the need to install plugins or download native apps.

Can I completely disable WebRTC in my browser?

Yes, but the method varies by browser. Firefox allows complete disabling through about:config settings. Chrome, Edge, and other Chromium-based browsers require extensions to disable WebRTC functionality. However, disabling WebRTC completely may break some websites that rely on this technology for voice/video calls or file sharing.

Will a VPN protect me from WebRTC leaks?

Not all VPNs protect against WebRTC leaks by default. Some premium VPN services have built-in WebRTC leak protection, while others require you to manually configure settings or use browser extensions. Always verify that your VPN offers WebRTC leak protection and test it using tools like ours.

How often should I test for WebRTC leaks?

You should test for WebRTC leaks whenever you:

  • Install or update your browser
  • Change VPN providers or update your VPN software
  • Install new extensions that might affect networking
  • Before accessing sensitive content or websites where privacy is crucial
Can websites detect if I'm blocking WebRTC?

Yes, websites can potentially detect if WebRTC is disabled or blocked. Some websites that rely on WebRTC functionality (like video conferencing sites) may prompt you to enable it or may not function properly. However, most regular websites won't notice or care if WebRTC is disabled.
