WebRTC Leak Test – Check Browser IP Leaks Free & Easy

Use our easy tool to see if your browser is leaking you IP. You can run the test again after you’ve activated a VPN for example to see if that changes your visible IP.

WebRTC Leak Test

This tool checks if your browser is leaking your local IP addresses via WebRTC.

Running test…

WebRTC leaks are an often-overlooked privacy risk that can expose your real IP address even if you’re using a VPN or proxy. If you’re concerned about online security, knowing whether your browser is leaking your IPv4 or IPv6 address is crucial.

This guide will explain what WebRTC is, why leaks happen, and how to protect yourself. Plus, you can use our free WebRTC leak test tool above to check if your real IP is exposed.

What Is WebRTC?

WebRTC (Web Real-Time Communication) is a built-in browser technology that enables peer-to-peer communication. It allows websites and applications to provide features like:

✅ Video calling (e.g., Google Meet, Zoom, and Discord)
✅ Live streaming
✅ File sharing

Since WebRTC enables direct device-to-device communication, it needs to discover your real IP address to establish a connection. The problem? Even if you’re using a VPN or proxy, WebRTC can sometimes bypass it and reveal your actual IP.

What Is a WebRTC Leak?

A WebRTC leak happens when your browser exposes your IP address through WebRTC’s peer-to-peer connections—even when you’re connected to a VPN or proxy.

🔹 Without a VPN, your IP is normally visible. No surprise there.
🔹 With a VPN, your real IP should be hidden—but WebRTC can still expose it if not properly configured.

This means that a website, advertiser, or malicious attacker could see your real IP address, even if your VPN is active.

Example Scenario:

  • You use a VPN to appear as if you’re in the US.
  • A website uses WebRTC to extract your IP.
  • If your browser leaks WebRTC data, the site sees your real IP (from your actual location), bypassing your VPN.

This is a major privacy flaw—especially for users relying on VPNs for anonymity.

How to Check for a WebRTC Leak

🔍 Step 1: Use the WebRTC leak test tool above.
🔍 Step 2: If you see an IP address that matches your real location, your WebRTC may be leaking.
🔍 Step 3: If only the VPN-assigned IP appears, you’re safe.

What You Should See in a Safe Setup:
✅ No local/private IP addresses (e.g., 192.168.x.x or 10.x.x.x).
✅ No real IP (matching your ISP’s assigned address).
✅ Only your VPN’s IP (if you’re using one).

How to Fix & Prevent WebRTC Leaks

If our WebRTC leak test shows your real IP, don’t worry—fixing it is simple.

1. Disable WebRTC in Your Browser

Most browsers enable WebRTC by default, but you can disable it to prevent leaks.

🟢 Chrome (Desktop & Mobile)

  • Use an extension like “WebRTC Control” to block WebRTC.
  • There’s no built-in setting to disable WebRTC in Chrome.

🟢 Firefox

  • Type about:config in the address bar.
  • Search for media.peerconnection.enabled.
  • Set it to false (this disables WebRTC).

🟢 Microsoft Edge

  • Go to edge://flags/ in the address bar.
  • Search for “WebRTC STUN Origin Header” and disable it.

🟢 Safari (Mac & iOS)

  • WebRTC is restricted in Safari by default, but not fully disabled.
  • To block WebRTC completely, use content blockers or a VPN with WebRTC protection.

2. Use a VPN That Blocks WebRTC Leaks

The easiest way to fully protect your IP is to use a VPN with built-in WebRTC leak protection. Many top VPNs automatically block WebRTC leaks, preventing your real IP from being exposed.

🛡️ What to Look for in a Secure VPN:
✅ WebRTC leak protection (not all VPNs offer this!)
✅ IPv6 leak protection (WebRTC can expose IPv6 too)
✅ Kill switch (for extra security)

If your VPN doesn’t block WebRTC leaks, you can still disable WebRTC manually using the methods above.

Why Does WebRTC Leak My IP Even With a VPN?

Many people assume that once they connect to a VPN, their real IP is fully hidden. However, WebRTC works separately from standard browsing traffic.

🛑 Here’s why WebRTC bypasses VPNs:

  • A VPN routes your internet traffic through an encrypted tunnel.
  • WebRTC directly queries your device for connection details, ignoring the VPN tunnel.
  • This can result in your real IP leaking, even if your VPN is working properly.

FAQ – WebRTC Leak Test & Fixes

1. How do I know if my WebRTC is leaking my IP?

Use the WebRTC leak test above. If it shows your real IP, your browser is leaking.

2. Can I fix WebRTC leaks without a VPN?

Yes! The best way is to disable WebRTC in your browser settings.

3. Does WebRTC leak happen on all devices?

WebRTC leaks mainly affect browsers, so mobile apps (e.g., WhatsApp, Zoom) are less affected. However, mobile browsers like Chrome on Android can still leak your IP.

4. What if I need WebRTC for video calls?

If you need WebRTC (for Zoom, Google Meet, etc.), use a VPN with WebRTC leak protection instead of disabling it completely.

5. Is WebRTC a security risk?

By itself, WebRTC is not dangerous—it’s just a technology. The risk comes from WebRTC leaks, which can expose your real IP.
