Browser Fingerprint
See what every website can read about your browser, device and identity.
About this tool
Websites don't need cookies to recognize you. The combination of your user agent, screen size, timezone, installed fonts, language settings and graphics hardware forms a "fingerprint" that is often unique enough to track you across sessions — even in incognito mode.
This tool reads the same signals a tracking script would and shows them back to you, including canvas and WebGL hashes derived from how your GPU renders graphics. The more unusual your combination of values, the easier you are to single out. Antidetect browsers exist precisely to normalize or spoof these signals.
Frequently asked questions
No. Everything is computed locally in your browser. The values never leave your device.
Sites ask your browser to draw hidden text and shapes, then hash the result. Tiny differences in your GPU, drivers and OS produce a stable, identifying value — without any permission prompt.
Use a mainstream browser at default settings, disable unusual extensions, and consider a privacy-focused or antidetect browser that normalizes these signals. Paradoxically, heavy customization often makes you more identifiable.
