WebRTC Privacy Shield
Free Chrome extension that blocks WebRTC IP leaks. Protect your real IP address even when using a VPN. Simple toggle, zero configuration required.
WebRTC is a browser technology that enables real-time communication — but it can leak your real IP address even when you're using a VPN. WebRTC Privacy Shield intercepts this at the API level, letting you choose your protection level. Max Privacy mode completely disables non-proxied UDP so your real IP is never exposed. Balanced mode allows only your default public interface IP — no local or mDNS addresses. Switch it Off temporarily for sites that need WebRTC. The badge turns teal when protected and shows OFF in red when disabled. Your selected level persists across sessions.

Frequently Asked Questions
Everything you need to know about WebRTC Privacy Shield.
What is a WebRTC leak?
WebRTC is used for video calls and real-time features. It can expose your real IP address to websites even when you're using a VPN, because it bypasses the VPN tunnel.
Will this break video calls?
Max Privacy may affect some WebRTC-based video calls. Use Balanced mode for protection that keeps video calls working, or toggle Off temporarily on call sites.
Does it work with my VPN?
Yes. WebRTC Privacy Shield complements any VPN by closing the WebRTC leak that most VPNs don't address.
How do I stop WebRTC from leaking my IP in Chrome?
Install WebRTC Privacy Shield. Max Privacy mode stops direct UDP connections, and Balanced mode only allows your public interface.
Is there a Chrome flag for WebRTC loopback candidates?
No. Chrome already leaves loopback addresses out. The real control is the WebRTC IP handling policy, which this extension sets.
