Browser fingerprint check: Canvas, WebGL, audio and WebRTC
Check the network, graphics, audio, font, screen and device signals your browser reveals, then save one local snapshot and compare what changes.

-Advanced signals your browser can reveal
These checks run in this tab. A visible signal gives websites more details to combine, but this page cannot claim that your browser is unique without comparing it with a wider population.

Saving is optional. The snapshot stays in this browser until you remove it; this tool does not upload the JSON report or advanced signal results.
No snapshot saved yet. Save the current result, change your VPN or browser settings, then return to compare.
| Signal | Saved snapshot | Current result | Change |
|---|
Privacy note: advanced signals and the optional snapshot remain in this browser. The visible IP address, location and proxy summary come from the existing network request used to load the test.
Switch on a VPN, reload and compare
A VPN should first change the easiest signals: visible IP, location, provider and sometimes the WebRTC result. Test once without a VPN, then switch it on and reload this page.
- Start without a VPN Make a note of the visible IP, location and WebRTC result before changing anything.
- Enable your VPN Reload the page and check whether the visible IP, location and leak status have changed.
What this browser check looks at
This live test covers network, WebRTC, canvas, WebGL, audio, fonts, screen, regional settings, hardware and storage signals. A VPN mostly changes the network layer; browser and device settings influence nearly all the others.
IP
Your public IP is one of the quickest ways websites place and classify a visit.
WebRTC leak check
WebRTC can reveal network addresses outside the usual page request. That is why privacy-conscious users test it straight after enabling a VPN.
Canvas signal check
This test draws a known pattern in your browser and hashes the result. Small hardware and graphics differences can make that output easier to recognise.
Browser settings
Try a browser with stricter anti-fingerprinting defaults, or use a VPN that clearly includes WebRTC leak protection.
FAQs
What does the fingerprint checker show?
This live test covers network, WebRTC, canvas, WebGL, audio, fonts, screen, regional settings, hardware and storage signals. A VPN mostly changes the network layer; browser and device settings influence nearly all the others.
How can I check my browser fingerprint online?
Use the live checker on this page. It shows your IP address, location, browser profile, screen resolution, language settings, canvas fingerprinting and WebRTC leak detection in real time.
Can websites recognise me without cookies?
Yes. Fingerprinting can recognise patterns without cookies by combining device, browser, graphics, language, network and rendering details into a recognisable profile.
What does online fingerprint mean?
An online fingerprint combines IP data, device details, browser settings and technical behaviour signals that make your browsing session identifiable to websites.
Does this page save my fingerprint?
Not by default. Advanced signals are processed in this browser. A snapshot is stored locally only when you choose to save it, and you can remove it again. The network summary still uses the request that loads this test.
Does a VPN block canvas and WebRTC fingerprinting?
Not on its own. A VPN mainly changes your visible IP and location. Canvas fingerprinting happens in the browser, and WebRTC can still leak addresses unless the browser or VPN protects against it.
