Browser Fingerprint

See the signals a website can read from your browser with no permission at all — screen, time zone, CPU, canvas and WebGL — combined into a semi-unique hash. A privacy demo; nothing is uploaded.

This shows the signals a website can read from your browser without any permission — and combines them into a semi-unique “fingerprint” hash. It’s a privacy demonstration; nothing is sent anywhere.

How it works

The page reads freely-available browser properties — user agent, language, screen size and colour depth, time zone, CPU cores, device memory, touch support — plus a canvas and WebGL render signature, which vary subtly between devices and drivers. These are combined and hashed locally with a fast FNV-1a into one identifier. The point: even with cookies blocked, these signals alone can often single out a browser. Nothing here is uploaded or stored.
