WhatFont is a free Chrome add-on developed by TestDev that allows users to easily identify the font family used in any text on a web page. With this handy tool, users no longer need to guess or manually search for the font used on a website.

Once installed, WhatFont adds a small icon to the browser's toolbar. When users come across a piece of text that they are curious about, they simply click on the WhatFont icon and then hover over the text. Instantly, a small pop-up box appears, displaying the font family, size, line height, and color of the selected text.

The simplicity and effectiveness of WhatFont makes it a must-have tool for web designers, developers, and anyone interested in typography. Whether you're trying to match a font on your own website or simply curious about the typography choices made by other websites, WhatFont provides a quick and easy way to identify fonts without the need for complex software or manual searching.
