Browser Fingerprint Test

A browser fingerprint is a unique identifier built from dozens of signals: your browser type, OS, screen resolution, installed fonts, Canvas rendering output, timezone, language and more. Websites use this to identify users without cookies.

Yes. Advertisers and data brokers use browser fingerprints for cross-site tracking — even if you clear cookies or use Incognito mode, your fingerprint typically stays the same as long as your browser and device configuration doesn't change.

No. VPNs only change your public IP and geo-location — they don't affect Canvas output, WebGL info, screen parameters and other fingerprint sources. A VPN protects your IP privacy, and combining it with a privacy browser or extensions can further reduce tracking risk.

Use a privacy-hardened browser (Brave, Tor Browser), install anti-fingerprint extensions, avoid rare fonts/plugins, and use a common screen resolution. No single measure fully prevents tracking; combining approaches works best.
