Browser & Device Fingerprint
See your browser and device fingerprint — canvas, WebGL, audio, fonts, and more.
About this tool
Inspect the signals sites can use to recognize your browser and device: canvas, WebGL, WebGPU, audio, fonts, speech voices, WebRTC, Client Hints, math fingerprint, CSS/media preferences, permissions, storage, and a composite SHA-256 ID. Everything runs locally — nothing is uploaded.
What you get
- Composite SHA-256 fingerprint ID from stable browser signals
- Canvas, WebGL, WebGL2, WebGPU, and AudioContext fingerprints
- Fonts, speech voices, math fingerprint, and WebRTC ICE hints
- Screen, timezone, Intl APIs, Client Hints (UA-CH), and CSS media queries
- Feature detection, permissions, storage quota, battery, and ad-block heuristic
- Export full report as JSON
How to use
Click Run fingerprint scan. The check runs entirely in your browser. Copy the fingerprint ID or export JSON to compare across browsers or privacy tools.
FAQ
What is a browser fingerprint?
A browser fingerprint is a set of technical signals—screen size, installed fonts, graphics rendering, audio stack, and more—that sites can combine to recognize a browser session. It is often used for fraud detection, analytics, and tracking resistance testing.
How can I test if my browser is unique?
Run a fingerprint scan and compare the composite ID across browsers, profiles, or privacy extensions. Large differences in canvas, WebGL, or font lists usually mean a distinct fingerprint.
Which signals affect browser fingerprinting most?
Canvas rendering, WebGL vendor/renderer strings, audio context output, installed fonts, and timezone often contribute heavily. Client Hints and screen resolution add further variation.
Can canvas and WebGL identify my device?
They rarely identify hardware alone, but the rendered output and GPU strings are stable enough to help distinguish your browser from others when combined with other signals.
