Browser Fingerprint Test
Websites don't need cookies to track you. Your browser sends dozens of unique signals that together identify you across the internet — even in incognito mode.
What Is Browser Fingerprinting?
Browser fingerprinting is a tracking technique that identifies you by collecting your browser's unique combination of settings — screen size, fonts, graphics hardware, timezone, language, and more. Unlike cookies, you can't delete your fingerprint by clearing browser data.
Advertising networks and data brokers use fingerprinting to track you across private/incognito browsing sessions, across different browsers on the same device, and even after clearing all cookies.
Does a VPN Stop Fingerprinting?
No. A VPN hides your IP address but does nothing to change your browser fingerprint. Canvas rendering, WebGL output, installed fonts, screen resolution, timezone — none of these are affected by a VPN. You remain uniquely identifiable.
How to Reduce Your Browser Fingerprint
- Firefox — go to
about:config, search forprivacy.resistFingerprinting, set totrue. This makes Firefox report standardized values for most fingerprinting signals. - Brave Browser — has built-in fingerprint randomization enabled by default. No configuration needed.
- Tor Browser — strongest protection. Makes your fingerprint identical to thousands of other Tor users by design.
- uBlock Origin — blocks most third-party fingerprinting scripts before they run.
