The WhatFont extension is a tool that allows users to identify fonts used on web pages. It is available as a free Google Chrome extension and a Firefox add-on. The extension works by allowing users to hover over text on a web page to see information about the font, including its size, color, and family. It can also detect the services used for serving the web fonts, such as Typekit and Google Font API. The WhatFont extension is useful for web designers, marketers, and developers who need to quickly identify fonts on a web page.
