Font Thief is a free Chrome add-on designed for quick and effective font identification on websites. By simply hovering over any text, users can instantly view detailed font information including family, size, weight, and color. This tool serves as a modern replacement for the now-defunct WhatFont, offering a user-friendly interface that streamlines the process of font detection without the need to delve into developer tools.

In addition to its primary function, Font Thief allows users to perform a comprehensive typography audit of any webpage, showcasing all fonts used along with their frequency. Users can also extract color palettes from the page with a simple click. The extension prioritizes user privacy by processing all data locally without collecting any personal information or making network requests.
