Google Web Fonts
A web with web fonts is more beautiful, readable, accessible and open.
Google Web Fonts makes it quick and easy for everyone to use web fonts, including professional designers and developers. We believe that everyone should be able to bring quality typography to their web pages and applications.
Our goal is to create a directory of web fonts for the world to use. Our API service makes it easy to add Google Web Fonts to a website in seconds. The service runs on Google's servers which are fast, reliable and tested. Google provides this service free of charge.
