Browser Fingerprint Test

Discover how uniquely identifiable your browser is. We collect canvas hash, WebGL renderer, fonts, screen properties and over 20 other signals to calculate your fingerprint and estimate how trackable you are across websites.

Canvas Fingerprint Preview

This canvas renders differently across browsers and devices — tiny variations create a unique hash used to identify your browser.

What Is Browser Fingerprinting?

Browser fingerprinting is a tracking technique that collects information about your browser configuration to create a unique identifier. Unlike cookies, fingerprints do not require any data to be stored on your device — they are reconstructed from browser signals every time you visit a site.

Every browser leaks dozens of signals: your user agent string, screen resolution, installed fonts, canvas rendering output, WebGL capabilities, audio processing characteristics, and more. When combined, these signals create a fingerprint that can be unique enough to identify you across websites, sessions and VPNs.

Studies show that over 90 percent of browsers can be uniquely identified through fingerprinting. This makes it one of the most powerful and privacy-invasive tracking methods in use today, because it is largely invisible and cannot be blocked by standard privacy tools.

How to Reduce Your Fingerprint

Use Brave Browser

Brave blocks fingerprinting by default by randomizing canvas and WebGL output. It is the most effective solution for most users with no configuration required.

Firefox with Privacy Settings

Enable privacy.resistFingerprinting in about:config. This makes Firefox report generic values for many fingerprinting signals, significantly reducing uniqueness.

Tor Browser

Tor Browser standardizes all fingerprint signals so every user looks identical. It provides the strongest fingerprint protection but sacrifices speed and some functionality.

Frequently Asked Questions

Does a VPN protect against fingerprinting?

No. A VPN hides your IP address but does nothing to change your browser fingerprint. Websites can still identify and track you across sessions using canvas, WebGL, and other browser signals even when your IP changes with every VPN connection.

Can I block canvas fingerprinting?

Yes. Brave browser blocks canvas fingerprinting by adding subtle noise to canvas output that changes with each site visit. Firefox with privacy.resistFingerprinting enabled returns a blank canvas. Extensions like CanvasBlocker can add this protection to Chrome.

Is my fingerprint the same on every website?

Yes, unless you change browser settings or use fingerprint protection. The same browser on the same device will produce a consistent fingerprint across all websites that check it, which is exactly what makes it useful for cross-site tracking.

What is the canvas fingerprint?

A canvas fingerprint is generated by drawing text and shapes to a hidden HTML canvas element and converting the result to a hash. Tiny differences in font rendering, antialiasing and GPU output between devices produce different results, creating a unique identifier.

What is WebGL fingerprinting?

WebGL fingerprinting reads information about your GPU — vendor, renderer, supported extensions and rendering behavior. The combination of GPU model, driver version and operating system creates a highly unique fingerprint component that persists across browser restarts.

Does incognito mode prevent fingerprinting?

No. Incognito mode only prevents your browser from saving local history and cookies. Your browser still sends the exact same user agent, canvas, WebGL and screen data in incognito mode as in normal mode. Fingerprinting works identically in both.
