What is a browser fingerprint?
Even without cookies, a site can combine screen size, fonts, canvas, timezone, and more into a signature that often identifies one browser among many.
Why you should care
Advertising and anti-fraud systems use fingerprints when cookies are blocked or cleared. A stable fingerprint can link visits even as the IP changes.
A VPN is the wrong tool for this problem. It changes the network identity, not the browser’s hardware and software quirks.
What gets combined
Common signals include user agent, screen metrics, timezone, language, canvas and WebGL rendering, audio processing, and installed fonts.
Each piece is weakly identifying. Together they can become rare — sometimes unique in a sample of visitors.
VPN hides
Your public IP can change
- Your device
- VPN exit IP
- Website
Fingerprint stays
The browser still looks like you
- Your device
- Canvas, fonts, timezone
- Website
Uniqueness needs a visitor sample
Sites like AmiUnique compare your fingerprint to a stored panel. SkyPath does not keep that panel, so the tool does not show a uniqueness percentile.
Use the values to see what a site can read — especially canvas and WebGL — not as a score you can win.
How to check
Run a fingerprint test in this browser, then again in a different browser or a stricter privacy profile, and compare which signals moved.
Connect a VPN and re-run: the fingerprint should look largely the same if only the IP changed.
Remember
- Fingerprinting is local to the browser — a VPN will not reset it.
- Blocking one API (for example canvas) can itself become a distinctive choice.
- A uniqueness percentile requires a visitor panel this tool does not keep.
- Re-check after browser updates.
