Canvas Fingerprint Test
Test your browser's canvas fingerprinting vulnerability by generating a unique fingerprint that websites can use for tracking.
Canvas Fingerprint Test
This tool generates a unique canvas fingerprint that websites can use to track your browser. Canvas fingerprinting is a privacy-invasive tracking technique.
Your Canvas Fingerprint
This fingerprint can be used to track you across websites. Consider using privacy extensions that block canvas fingerprinting or randomize the output.
How it Works
This tool draws text and shapes on an HTML5 canvas element and converts the result to a hash. Different browsers, operating systems, and graphics drivers produce slightly different outputs, creating a unique fingerprint.
What is Canvas Fingerprinting?
Canvas fingerprinting is a tracking technique that exploits subtle differences in how browsers render graphics. Even identical content can produce different pixel data due to variations in graphics hardware, drivers, and rendering engines.
Technical Details
- Browser Extensions: Use privacy extensions like CanvasBlocker, Privacy Badger, or uBlock Origin with canvas fingerprinting protection.
- Tor Browser: Tor Browser includes built-in canvas fingerprinting protection.
- Firefox: Firefox has built-in fingerprinting protection that can be enabled in privacy settings.
