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.
Loading results...
The totals cover nine browser checks; they are not a privacy rating. A readable signal need not be unique, and an absent result is no guarantee of protection.
Network request
- Visible IP address
- -
- Browser details
- -
- Proxy/VPN status
- Not available
- Approximate location
- -
These readings come from loading this page. The IP location is an estimate, and proxy detection may be inaccurate.
WebRTC address exposure
- IPs found
- -
- Address result
- -
This local WebRTC check uses no STUN servers. Finding no address does not rule out a VPN leak.
Canvas render signature
-A canvas hash represents this drawing, rather than a unique identity. A changed hash on its own does not demonstrate stronger protection.
Save a snapshot, change settings and compare
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.
Change a single setting, then compare. After switching your VPN, reload the page to update the IP. Run tests again repeats the browser checks only.
No snapshot saved yet. Save the current result, change your VPN or browser settings, then return to compare.

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.
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.
WebGL graphics
Loading results...-
Many devices can report the same graphics details.
Audio fingerprint
Loading results...-
Audio is calculated offline, without using the microphone or playing any sound.
Available fonts
Loading results...This checks a selection of nine fonts, rather than listing every installed font.
Screen and pixel ratio
Loading results...Screen dimensions are different from the size of the browser window.
Time zone and language
Loading results...The browser's language and time zone may differ from the IP location.
Device capabilities
Loading results...Browser privacy settings may round or alter these readings.
Browser storage
Loading results...Storage being available does not indicate that a tracking cookie was found.
Switch on a VPN, reload and compare
Save the initial result, switch your VPN connection and reload the page. Check whether the visible IP changes; browser signals may remain unchanged.
FAQ
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?
Check the network, graphics, audio, font, screen and device signals your browser reveals, then save one local snapshot and compare what changes. Change a single setting, then compare. After switching your VPN, reload the page to update the IP. Run tests again repeats the browser checks only.
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?
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.
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.
