Google FontsGoogle Fonts makes product and web pages run faster by safely caching fonts without compromising users’ privacy or security. Our cross-site caching is designed so that you only need to load a font once, with any website, and we'll use that same cached font on any other website that uses Google Fonts.
Using the code generated by Google Fonts, our servers will automatically send the smallest possible file to every user based on the technologies that their browser supports. For example, we use WOFF 2.0 compression when available. This makes the web faster for all users—particularly in areas where bandwidth and connectivity are an issue. Now everyone can enjoy the same quality and design integrity in their products and web pages, no matter where they are in the world.
Collaborate with Open SourceAll the fonts in our catalog are free and open source, making beautiful type accessible to anyone for any project. This means you can share favorites and collaborate easily with friends and colleagues. Google Fonts takes care of all the licensing and hosting, ensuring that the latest and greatest version of any font is available to everyone.
You can download all Google Fonts in a simple ZIP snapshot (over 250Mb) from https://github.com/google/fonts/archive/master.zip
