Typekit is an Adobe service which allows embedding fonts into online and offline documents.
Typekit is a way to use professional fonts on the web. It can also be used for off-line documents for software that supports it.
Built around web standards, the Typekit service gives designers and developers a subscription-based library of hosted, high-quality fonts to use on their websites and off-line documents. A limited number of fonts are available for free use.
Typekit was founded in 2008 and acquired by Adobe Systems Incorporated in 2011
