What the
FØnŧ?!

What the Font crawls the target URL inside a secure Cloudflare cloud environment, parses every linked stylesheet, and extracts @font-face declarations, Google Fonts import URLs, and CDN links from services like Bunny Fonts and Fontshare.

Any font loaded over the network - Google Fonts, Bunny Fonts, Fontshare, and custom fonts declared with @font-face. System fonts like Arial or Georgia aren't fetched from external servers and cannot be detected.

Yes, completely free. No account required, no rate limits.

Results are cached for 24 hours. After that, the next visit triggers a fresh crawl automatically - or click "Re-analyze" on any site page to force an immediate rescan.

Use Chrome or Firefox DevTools: right-click the text → Inspect, then open the Computed tab and scroll to "Rendered Fonts". This shows the exact font being rendered on that element. For a full page inventory, use the URL scanner above.

Extensions like WhatFont and Fontanello are great for quickly checking a single element, but they can't give you a complete inventory of all fonts loaded by a page. A URL scanner detects every @font-face, Google Fonts import, and CDN font in one pass.

Yes - paste the URL and look for fonts marked with source "Google Fonts". If present, the site is making external requests to fonts.googleapis.com, which is relevant for GDPR compliance.

Yes - that is the main advantage of What the Font. Just paste the URL in the box above and you get a complete font inventory within seconds. No extension, no plugin, no account required.

Google Fonts and Bunny Fonts are detected and labeled automatically. Custom @font-face fonts - whether self-hosted or loaded from a CDN - are also captured. Adobe Fonts (Typekit) can be detected if the font-face declarations are accessible in the stylesheet.

A URL scanner only detects fonts loaded via CSS. If the font is embedded in an image or logo, it was not loaded as a web font - but you can try image-based tools like WhatTheFont by MyFonts, Google Lens, or Font Squirrel Matcherator. See our font-from-image guide for step-by-step instructions.

Extensions show you the font on a single element you hover over. What the Font scans the entire page at once and lists every font loaded - including ones on components not currently visible. It also works without installing anything and can be used on any device.
