What Is Browser Fingerprinting?

Browser fingerprinting is a tracking technique that identifies users by collecting unique characteristics of their browser and device — without using cookies. By combining attributes like your canvas rendering, WebGL GPU identifier, screen resolution, installed fonts, timezone, and language settings, websites can create a unique "fingerprint" that identifies you across sessions.

Unlike cookies, which you can delete or block, fingerprints are passive and invisible. They're generated from information your browser provides automatically to render web pages. Advertising networks and analytics companies use fingerprinting to track users who block cookies, making it one of the hardest tracking methods to prevent.

How to Reduce Your Fingerprint

Use Firefox with Enhanced Tracking Protection set to Strict, or enable privacy.resistFingerprinting in about:config. The Tor Browser is the gold standard — it standardizes all fingerprint signals to match other Tor users. Browser extensions like Canvas Blocker can help, but ironically, having unusual extensions makes your fingerprint more unique. A VPN hides your IP but doesn't prevent fingerprinting.

FAQ

What is browser fingerprinting?

Browser fingerprinting identifies users by collecting unique characteristics of their browser and device — canvas rendering, WebGL renderer, screen size, fonts, plugins, and more. Combined, these create a unique ID that persists across sessions without cookies.

Can a VPN prevent fingerprinting?

No. A VPN hides your IP address and encrypts your traffic, but it doesn't change your browser's fingerprint. You need browser-level protections like Firefox's resist fingerprinting mode or the Tor Browser to reduce your fingerprint.

What does the uniqueness score mean?

The score estimates how identifiable your browser is based on the entropy of collected signals. A higher score means your combination of browser attributes is more rare, making you easier to track across websites.

Is 100% uniqueness bad?

A high uniqueness score means your browser configuration is rare enough to be individually identifiable. For maximum privacy, you want a common fingerprint that blends in with many other users — which is what the Tor Browser achieves.
