Tool — 100% Client-Side · Nothing Leaves Your Device

Browser Fingerprint Analyzer

Even without cookies, websites can identify you by the unique combination of your browser settings, hardware, and installed fonts. This tool shows you exactly what fingerprint your browser is broadcasting — and how unique it is.

Results show what your browser is currently broadcasting. Compare your values to the most common values to see where you stand out. Use Save as Baseline before making changes to measure your progress. After running the analyzer, use the Test Active Protection button to check whether your privacy extensions are actually working.

What does your browser reveal?

Each data point below is collected silently by websites you visit. Together they create a fingerprint that can identify you across sites without any cookies or login.

User Agent
Waiting
The raw string your browser sends to every website. Identifies your browser, rendering engine, and OS without consent.
Browser & OS
Waiting
Parsed from your user agent. Browser name and version combined with OS narrows your identity significantly.
Screen Resolution
Waiting
Screen dimensions reveal display hardware and device class. Combined with pixel ratio, it is highly distinctive. Screen resolution spoofing cannot be detected — extensions that spoof this value are indistinguishable from a genuine screen at that resolution.
Timezone
Waiting
Your local timezone reveals your geographic region even when your IP is masked by a VPN or proxy.
Language
Waiting
Browser language settings reveal your locale and preferred language, often correlating with geographic location.
Platform
Waiting
navigator.platform identifies your OS at the hardware level. Paired with screen size, it narrows your hardware profile.
Do Not Track
Waiting
This header signals you don't want to be tracked. Most advertising networks ignore it — it has no legal enforcement.
Cookies Enabled
Waiting
Knowing cookies are enabled allows sites to set persistent tracking identifiers on your device.
JavaScript Enabled
Waiting
JavaScript enables nearly all modern fingerprinting. If you're reading this, it is active in your browser.
Canvas Fingerprint
Waiting
Your GPU and graphics drivers render graphics slightly differently than others. This hash represents your unique rendering signature.
WebGL Renderer
Waiting
WebGL exposes your GPU model and driver version — one of the most stable cross-session fingerprinting vectors.
Installed Fonts
Waiting
Font presence is detected via canvas width measurement. Your font set is shaped by your OS, region, and installed software.
Touch Support
Waiting
Reveals whether you're on a touch device. Combined with screen resolution, it identifies device class and form factor.
CPU Cores
Waiting
navigator.hardwareConcurrency exposes your logical CPU core count. Combined with GPU and memory, it profiles your hardware tier.
Device Memory
Waiting
navigator.deviceMemory reports approximate RAM in GB. Intentionally imprecise, but still useful for fingerprinting device class.
Connection Type
Waiting
The Network Information API exposes your effective connection type (4G, 3G, etc.). Not available in all browsers.
