Browser Fingerprint Protection: How Antidetect Browsers Work

Every browser leaks dozens of signals websites combine into a unique fingerprint. Clearing cookies doesn't help. Here's what's tracked and how to hide it.

What websites collect

  • Canvas fingerprint — pixel-level rendering differences
  • WebGL fingerprint — GPU signature
  • WebRTC — real local + public IP leak
  • AudioContext — audio stack signature
  • Fonts, screen size, timezone, language
  • User-Agent + Client Hints

How antidetect browsers defeat it

They spoof each signal per profile with values from a real device database, keep them consistent, and route traffic through a matching proxy.

Signals to verify

Test each profile on:

  • browserleaks.com
  • pixelscan.net
  • iphey.com

A good antidetect browser scores "consistent" across all three.

FAQ

Can incognito mode replace an antidetect browser?

No — incognito only clears cookies; your fingerprint stays the same.

Do VPNs hide fingerprints?

No, only IPs. You still need a fingerprint spoofer.
