If you have run Anonymiz's browser fingerprint test, you probably saw a list of technical values and a uniqueness score and wondered what any of it actually means. This guide walks through each result and explains what it tells you about how trackable your browser really is.
What the Uniqueness Score Means
Your fingerprint test gives you a percentage — for example, "98% of browsers tested have a different fingerprint than yours." That number is not a vague estimate. It comes from comparing your specific combination of signals against a large sample of real browser fingerprints collected from other visitors.
A score above 95% means your browser configuration is close to unique. Even without cookies, a site that runs the same checks could recognize you on a return visit by matching that combination again.
Canvas and WebGL: Why They Score High
Two of the biggest contributors to your score are usually canvas and WebGL rendering. When a page draws a hidden image using your graphics hardware and drivers, tiny differences in how your specific GPU and driver version render that image produce a near-unique signature. This happens before you click anything, and clearing cookies does not change it.
Fonts and Plugins
The list of fonts installed on your system is more identifying than most people expect. Most users install software that quietly adds fonts over time — design tools, office suites, PDF readers — and the resulting list becomes a fingerprint component on its own. The same applies to browser plugins and extensions that expose themselves to the page.
What a High Score Actually Means for You
A high uniqueness score does not mean you have done anything wrong. It means your specific combination of hardware, OS, browser version, and installed software happens to be uncommon. Two people using the exact same laptop model, OS version, and browser can still get different scores if their installed fonts or plugins differ even slightly.
What Actually Lowers the Score
Standard privacy advice like clearing cookies or using incognito mode does not change your fingerprint score, because none of the signals it measures are stored in a cookie. What does help:
- Use a browser built to resist fingerprinting. Tor Browser and Firefox's resistFingerprinting mode standardize what your browser reports, so large groups of users look identical.
- Disable or limit canvas/WebGL access. Some browser extensions block canvas reads or return randomized noise instead of the real rendering.
- Reduce installed fonts and unnecessary plugins. Fewer unique software signals means less to fingerprint.
- Run the test again after changes. The score updates live, so you can confirm whether a setting change actually helped.
