Browser Environment
Browser Fingerprint Test
The individual signals your browser exposes, and how they combine into a value that tends to stay stable for one device. All of it is computed here and none of it is uploaded.

How this works
A set of independent measurements is taken in your browser — canvas rasterisation, audio processing rounding, installed fonts, graphics details and environment values. They are combined into a single hash. The hash is computed locally and is never transmitted.
Input
- No input required
Output
- A locally computed fingerprint identifier
- The individual components that produced it
- Canvas, audio and font signal values
- Which components failed or were blocked
- A stability assessment
Privacy
The fingerprint and all of its components stay in your browser. No request carries them anywhere. The engine is explicitly configured with telemetry disabled.
Limitations
- This tool does not and cannot tell you how unique you are; that requires population data it does not have.
- A fingerprint is a change-detection value: if it changes, something about your browser changed.
- Browsers that resist fingerprinting will block components, producing a partial result.
- A stable fingerprint is not inherently bad — it is a trade-off against other browser features.
Frequently asked questions
What is browser fingerprinting?
It is the practice of combining many small, individually unremarkable facts about a browser — screen size, fonts, graphics driver, audio behaviour — into a value that tends to stay the same for one device.
Can this tell me how unique my browser is?
No. Measuring uniqueness requires comparing you against a large population of other visitors. This tool has no such data and does not guess.
Is my fingerprint uploaded?
No. It is computed and displayed entirely in your browser.
Why do some components show as blocked?
Privacy-focused browsers deliberately return blank canvases or generic values to defeat fingerprinting. That produces an honest partial result rather than a fake one.
