  2. View your fingerprint - See all exposed data (fonts, plugins, canvas hash)
  3. Check uniqueness score - How identifiable you are (lower is better)
  4. Get privacy tips - Suggestions to reduce fingerprinting surface

How Browser Fingerprinting Works

Your browser reveals 30+ data points: User agent, screen size, timezone, installed fonts (via document.fonts), canvas rendering (unique to GPU/drivers), WebGL vendor/renderer, audio context properties, and more. Combined, these create a unique 'fingerprint' - even with cookies disabled.

Canvas fingerprinting explained: Websites draw hidden text/shapes on a <canvas> element, then read pixel data with toDataURL(). Tiny differences in GPU rendering, font rendering, and anti-aliasing create unique hashes. This tool demonstrates the technique by showing your canvas hash.

Pro tip: To reduce fingerprinting: use Tor Browser (randomizes fingerprint), enable Firefox's resistFingerprinting flag, disable JavaScript on untrusted sites, or use browser extensions like Canvas Blocker. But beware: being too unique (e.g., only Tor user on a site) can make you stand out. The sweet spot is 'blending in' with a common configuration.
