Lightweight local check

Font Fingerprint Test

Measure a small list of common fonts locally to see whether font availability may add browser-visible detail.

This is a limited font signal, not a complete font inventory. It checks only a small controlled list and does not send results to a server.

What this checks

The page measures text widths through a local canvas and compares a small common-font list against generic fallback fonts.

A likely detected font means the measured width differed from generic fallback behavior in this browser session.

Limitations

  • The list is intentionally small to keep the page lightweight.
  • Browser font fallback behavior can cause false positives or false negatives.
  • The result does not measure all installed fonts.
  • No font result is sent to a backend API.

Reduce exposure

What to do next

Font exposure is usually reduced by browser-level protections rather than manual font removal.

  1. Use privacy-focused browser settings that standardize or restrict font access.
  2. Avoid installing rare fonts only for general browsing profiles.
  3. Use separate browser profiles for work that needs special fonts.
