Browser Fingerprint Test
Review browser and device attributes that websites can combine into a fingerprint. The test runs locally and does not claim to measure how unique you are across the web.
Analyzing browser fingerprint...
What is Browser Fingerprinting?
Browser fingerprinting collects dozens of attributes about your browser and device to create a probabilistic identifier. This includes your screen resolution, installed fonts, browser plugins, timezone, and even how your graphics card renders images.
Unlike cookies, many fingerprint inputs come from browser, device, locale, and rendering behavior. Privacy-focused browsers may standardize or reduce some of these signals.
Fingerprinting Techniques
Canvas Fingerprinting
Uses HTML5 Canvas to draw graphics that render differently on each device.
WebGL Fingerprinting
Identifies your graphics card and driver through WebGL rendering.
Font Detection
Detects which fonts are installed on your system.
How to Reduce Your Fingerprint
- 1.Use the Tor Browser, which is designed to make all users look identical
- 2.Use Brave Browser with its built-in fingerprint randomization
- 3.Install privacy extensions like CanvasBlocker or Privacy Badger
- 4.Use Firefox with privacy.resistFingerprinting enabled in about:config
Frequently Asked Questions
What is browser fingerprinting?
Browser fingerprinting is a technique websites use to identify and track users by collecting information about their browser and device. Unlike cookies, fingerprints cannot be easily deleted and work even in private/incognito mode.
How does canvas fingerprinting work?
Canvas fingerprinting draws graphics using your browser and extracts the resulting image data. Differences in hardware, drivers, fonts, and browser behavior can make that output useful as one input to a broader fingerprint.
Can I prevent browser fingerprinting?
You can reduce fingerprinting by using privacy-focused browsers like Tor or Brave, installing anti-fingerprinting extensions, disabling JavaScript (though this breaks most sites), or using browser settings that block canvas/WebGL access.
Can this test tell me how unique my browser is?
No. A reliable uniqueness measurement requires comparison with a representative population over time. This test shows attributes and a local sample hash, but it does not assign a uniqueness or anonymity score.
