What is Browser Fingerprint Checker?
Browser Fingerprint Checker runs the same probes tracking companies use - canvas image hashing, WebGL renderer lookup, offline-audio graph rendering, font detection, and hardware and locale readouts - entirely in your browser, then summarizes how many bits of uniqueness you expose.
Key Benefits
- See your real trackability instead of abstract privacy advice
- All probes run locally - results never touch a server
- Hashed fingerprints show what stays stable across visits
- Compare browsers to pick your most private daily setup
- Fast: the whole analysis completes in a couple of seconds
Common Use Cases
- •Auditing how unique your browser setup is before hardening it
- •Comparing privacy browsers, containers, and anti-fingerprint extensions
- •Teaching teams why incognito alone does not stop tracking
- •Verifying that a privacy extension actually randomizes fingerprints
How to Check Your Browser Fingerprint
- Start the analysis: Click the analyze button - canvas, WebGL, audio, fonts, and hardware probes run locally in seconds.
- Read your probes: Review each fingerprint value; hashes that stay the same across visits are what trackers key on.
- Reduce your entropy: Try a privacy browser or extension and re-run the analysis - fewer unique values mean weaker tracking.
Key Features
- Canvas fingerprint rendered and hashed locally, never uploaded
- WebGL renderer and vendor probe with debug renderer info
- Audio fingerprint from an OfflineAudioContext compressor graph
- Installed-font detection by text-width measurement
- Screen, timezone, languages, CPU cores, and memory readout
- Entropy estimate that quantifies how trackable your setup is
