Font Checker Pro

See which fonts a page really renders, highlight where they are used, and look up licenses. Runs locally; no tracking.

Find out what fonts any website actually renders, not just what the CSS lists. - Real rendered fonts with usage percentage, weights, italics and sizes - Hover or focus a font to outline where it appears, including same-origin iframes - Font files loaded: format, host, third-party and CDN flags - Page summary: font count, weight count, third-party requests, plus a guideline hint - License badges (open, system, Adobe, commercial, unknown) with "check license" links. Informational only, not legal advice - Copy results as JSON or CSS - Keyboard friendly, light and dark mode Privacy: no tracking, no analytics, no remote code. The optional license lookup (off by default) sends only font family names to the public fontcheckerpro.com catalogue, never the page URL or text.
