What Font Detector does

The website font detector reads @font-face rules, stylesheets, and the font-family stack set on each element after the page renders. It lists font families, weights, styles, and usage counts, then connects them with available font-face source URLs and likely providers.

The report separates @font-face definitions from the font stacks used on page elements and in stylesheets. A stack lists fonts in order of preference, so the report does not prove which one the browser drew. It is useful for checking a redesign, finding leftover weights, or documenting typography.

Questions about Font Detector

Something missing? Ask us.

Can it tell which font is rendered?

Not exactly. It reports the font-family stack each element asks for and the matching @font-face definitions. The browser draws the first available font in the stack, and the report does not confirm which one that was.

Does it download font files?

No. It inventories families and public source URLs. Font licensing and downloads remain the responsibility of the site owner or user.

Why are several weights listed for one family?

The page may use different weights for headings, body text, labels, or buttons. Usage counts help show which variants appear most often.
