What is browser fingerprinting?
Sites can combine user agent, timezone, screen size, canvas pixels, and WebGL renderer to recognize a returning browser — even with cookies cleared.
Canvas draws fixed text and shapes, then hashes the pixels. WebGL can expose the graphics vendor and renderer. Those rows are usually the most distinctive.
VPN vs fingerprint
DNS leak, WebRTC leak, and VPN detection answer network privacy. This page answers browser identity. An IP change does not hide the table.
How to reduce fingerprinting
Use a browser with built-in anti-fingerprinting, keep defaults common, and re-run this test after each change. Blocking one API can itself become a distinctive choice.
