What Does Font Foundry Mean?
A font foundry is a resource for finding, purchasing, acquiring and sharing active fonts. These entities are typically websites that distribute the fonts as files intended for the end user to install on their personal computer, which would in turn activate them in their various word-processing applications (assuming they are compatible).
A font foundry is also known as a type foundry.
Techopedia Explains Font Foundry
The word "foundry" originally referred to factories where metals were cast, including for typesetting machines. The term has thus been applied to modern digital type, as many different fonts populate the realm of electronic content.
It used to be the case that websites required fonts that were web safe, meaning they were standardized to be understood and displayed over a variety of browsers. However, improvements in web and graphic technology have made it easier for more diverse fonts to be used online.
