Canvas Fingerprint Test

Render a small local canvas scene and hash the image output to see one browser-visible rendering signal.

Canvas output may vary by browser, operating system, GPU, fonts, and privacy settings. This does not prove you are uniquely identifiable and does not prove you are being tracked.

What this checks

The script draws text, shapes, colors, and a curve into an off-screen canvas, then hashes the rendered image data locally in your browser.

Sites can use canvas rendering as one signal because graphics stacks often produce small differences across devices and browser settings.

Limitations

  • No comparison dataset is used, so this page cannot measure rarity.
  • Privacy tools may block or randomize canvas output.
  • The hash can change after browser, driver, font, or operating-system changes.
  • The result is not uploaded to a backend service.

Reduce exposure

What to do next

Reducing canvas exposure is mostly a browser and extension choice.

  1. Use browser privacy settings that resist canvas probing when available.
  2. Keep the browser updated so privacy protections are current.
  3. Avoid installing many rare extensions that can add unusual rendering behavior.
