Measurement details
Search a property, or expand only the group you need.
Run the test to render a deterministic sample and calculate SHA-256.
Rendering and hashing happen locally. The Canvas image and signature are not uploaded.
Usage and result interpretation
- Run the deterministic render to inspect its SHA-256.
- Differences may reflect hardware/settings and do not identify users alone.
Inputs are processed in your browser and not uploaded for execution.
How to use Canvas Fingerprint Test
Render a repeatable Canvas scene and inspect the resulting image signature. Drawing engines, fonts and graphics acceleration can affect the result.
Understanding results and limitations
This is one drawing sample, not a definitive device identifier. Consider it alongside other browser signals.
