Google Fonts

Google Fonts is an open-source library of more than 1,500 font families that are free for both personal and commercial use. You can preview fonts with your own text, pair typefaces, and see how they look at different weights and sizes before choosing.

Developers can embed fonts with a single line of code or download them for local use, while designers appreciate the quality and variety. Because everything is open source and hosted for free, it has become the default typography resource for the web.
