Browser Fingerprint Analyzer - Check Your Privacy
See what your browser reveals to every site you visit: your canvas fingerprint, user agent, screen resolution, language, and timezone - the signals used to identify and track you across the web.

Understanding This Tool
What It Does
Analyze your browser's fingerprint - the unique combination of settings, extensions, and configuration that identifies your browser. This tool shows you what information websites collect to track and identify you.
Understanding the Results
- User Agent: The identifying string your browser sends with every request
- Browser & OS: Parsed from your user agent (browser name/version and operating system)
- Screen Resolution: Your screen width x height in pixels
- Language: Your browser's preferred language setting
- Timezone: Your local timezone, which hints at your region
- Canvas Fingerprint: A signature derived from how your device renders a hidden canvas image - it varies by GPU, drivers, OS and fonts, which makes it strongly identifying
Common Use Cases
- Privacy Assessment: Understand what tracking data you're exposing
- Anti-Fraud: Identify when the same user is accessing accounts from different devices
- Device Identification: Track devices without relying on cookies
- Bot Detection: Detect automated access that has uniform fingerprints
- Account Security: Alert users to access from unusual device fingerprints
Pro Tips & Best Practices
- Privacy Risk: Your fingerprint may be unique enough to identify you even without cookies
- Mitigation: Use privacy browsers or extensions to randomize fingerprints
- VPN/Proxy: These don't significantly change your browser fingerprint
- Updates: Browser/OS updates change your fingerprint, providing some privacy benefit
Frequently Asked Questions
No. The language, screen resolution, timezone, and canvas values are all computed in your browser with JavaScript and never sent anywhere. The one exception is your User Agent string, which your browser includes in every HTTP request by design, so it is read on the server purely to display it back to you. Nothing on this page is logged or saved.
A canvas fingerprint is produced by drawing text or graphics to a hidden HTML5 canvas and then reading the rendered pixels back out. Because the exact pixels depend on your GPU, graphics drivers, operating system, and installed fonts, the same drawing instruction produces subtly different output on different machines. This tool draws sample text and shows the start of the resulting data URL so you can see that signature.
No. A VPN or proxy changes the IP address websites see, but it does not touch your browser's language, screen resolution, timezone, or canvas output, which are what build the fingerprint. You can be re-identified across different IP addresses through the fingerprint alone. To reduce fingerprinting you need a privacy-focused browser or anti-fingerprinting settings, not just a VPN.
Yes. Fingerprinting reads characteristics your browser already exposes, so it does not depend on cookies and is not cleared by a private or incognito window. That is precisely why it is used as a cookieless tracking method. Clearing your cookies or browsing history does not change the values this tool reads.
Several of the values that make up a fingerprint are tied to your software environment. Your User Agent changes with each browser version, and graphics-driver or OS updates can alter how the canvas renders pixels. So an update can shift your fingerprint, which slightly reduces how long a single signature can track you.
Frequently Asked Questions
Does this tool send my browser fingerprint to a server or store it?
No. The language, screen resolution, timezone, and canvas values are all computed in your browser with JavaScript and never sent anywhere. The one exception is your User Agent string, which your browser includes in every HTTP request by design, so it is read on the server purely to display it back to you. Nothing on this page is logged or saved.
What is a canvas fingerprint, and why is it so identifying?
A canvas fingerprint is produced by drawing text or graphics to a hidden HTML5 canvas and then reading the rendered pixels back out. Because the exact pixels depend on your GPU, graphics drivers, operating system, and installed fonts, the same drawing instruction produces subtly different output on different machines. This tool draws sample text and shows the start of the resulting data URL so you can see that signature.
Will a VPN or proxy hide my browser fingerprint?
No. A VPN or proxy changes the IP address websites see, but it does not touch your browser's language, screen resolution, timezone, or canvas output, which are what build the fingerprint. You can be re-identified across different IP addresses through the fingerprint alone. To reduce fingerprinting you need a privacy-focused browser or anti-fingerprinting settings, not just a VPN.
Can browsers be tracked by fingerprint even without cookies or in incognito mode?
Yes. Fingerprinting reads characteristics your browser already exposes, so it does not depend on cookies and is not cleared by a private or incognito window. That is precisely why it is used as a cookieless tracking method. Clearing your cookies or browsing history does not change the values this tool reads.
Why does my fingerprint change after a browser or operating system update?
Several of the values that make up a fingerprint are tied to your software environment. Your User Agent changes with each browser version, and graphics-driver or OS updates can alter how the canvas renders pixels. So an update can shift your fingerprint, which slightly reduces how long a single signature can track you.

How this tool works: This tool runs in your browser and on our server in real time. Depending on the tool, results are computed directly from the input you provide or retrieved from live, authoritative data sources at the moment you run a lookup. We do not sell your data, and your lookups are kept private — any history shown here is stored only on your device.
