Free Browser Fingerprint Test — See How Trackable Your Browser Is

Find out how trackable your browser really is. This test collects 18 signals — canvas fingerprint, WebGL, timezone, screen, and more — entirely on your device, with per-signal uniqueness ratings. Nothing is collected, sent, or stored.

Websites can identify you without cookies by combining dozens of tiny signals from your browser — your canvas rendering, graphics card, screen, fonts, and timezone. Run this test to see your own fingerprint and learn exactly which signals make you unique.

Run the fingerprint test

Click the button to collect 18 browser signals in under a second. Each signal is shown with its value and a uniqueness rating so you can see which ones identify you most.

100% private

Your fingerprint is computed by JavaScript in this tab. No signal ever leaves your device — there is no server receiving anything.

No signup

No account, no email, no tracking pixel. Run the test as often as you like.

Free forever

The full signal breakdown, uniqueness ratings, and fingerprint hash are free with nothing locked behind a paywall.

How to use the Browser Fingerprint Test

1Click “Run fingerprint test”
The page gathers 18 signals from your browser in about a second — canvas rendering, WebGL details, screen size, timezone, languages, and more.
2Read your fingerprint hash
All signals are combined into one fingerprint hash at the top, with an overall uniqueness verdict explaining how identifiable this browser looks.
3Review each signal
Every signal shows its collected value plus a High, Medium, or Low uniqueness rating and a plain-English explanation of why it matters.
4Compare setups
Re-run the test in a private window, a different browser, or with a VPN to see which changes actually shrink your fingerprint.

Why privacy-conscious users run this test

18 real fingerprinting signals

Canvas fingerprint hash, WebGL renderer and vendor, user agent, platform, languages, timezone, screen resolution, color depth, CPU cores, device memory, touch support, and more — the same signals real trackers combine.

Uniqueness rating per signal

Every signal is rated High, Medium, or Low uniqueness with an explanation, so you learn which settings actually expose you instead of staring at raw values.

One combined fingerprint hash

All signals are hashed into a single fingerprint identifier, so you can compare browsers and settings at a glance.

Zero data collection, by construction

Most fingerprint test sites record your visit. This page makes no network requests at all — your fingerprint is computed and displayed locally, then forgotten when you close the tab.

Graceful on locked-down browsers

If your browser blocks canvas reading or hides WebGL details (as privacy browsers do), the test shows “unavailable” for those signals instead of crashing — which itself tells you your protections are working.

Learn what to change

The explanations tell you which levers matter: spoofing your user agent does little, but normalizing your canvas fingerprint or timezone does a lot.

Browser Fingerprint Test FAQs

What is browser fingerprinting?

It is a tracking technique that identifies your browser by combining many small, seemingly harmless signals — how your graphics card renders an image, your screen size, your timezone, your installed fonts. Individually each signal is common; combined, they are often unique to you, letting sites recognize you without cookies.

Is my fingerprint sent anywhere when I run this test?

No. This page performs zero network requests. The signals are read and hashed by JavaScript inside your browser tab, displayed to you, and discarded when you leave. There is no fingerprint database here — unlike some other test sites, we cannot see or store your result.

What does a “High uniqueness” signal mean?

It means that signal’s value varies a lot between browsers, so it does heavy work in identifying you. Canvas fingerprint and WebGL renderer are typically High because they depend on your exact GPU, drivers, and OS rendering quirks.

Why do some signals show “unavailable”?

Your browser or an extension is blocking that API — for example, privacy browsers like Tor and Brave can block canvas fingerprinting or mask WebGL details. That is a good sign: fewer readable signals means a smaller, less unique fingerprint.

Does a VPN change my fingerprint?

A VPN hides your IP address but does not change browser signals like canvas rendering, screen size, or timezone (your timezone can even contradict your VPN location, which is itself a signal). Re-run the test with and without your VPN to see for yourself.

Does private or incognito mode stop fingerprinting?

Mostly no. Private mode deletes cookies and history afterward, but the browser signals collected during the session — canvas, WebGL, screen, fonts — are usually identical. Run this test in a normal and a private window and compare the hashes.

How can I reduce my fingerprint uniqueness?

Use a browser with built-in fingerprint protection (Tor Browser is the strongest; Brave and Firefox with strict tracking protection help), keep your browser updated, avoid installing unusual fonts or extensions, and consider matching your timezone to your VPN location.
