Many websites, such as dafont and Font Squirrel, offer free fonts online that work for the latest edition of Microsoft Word. In addition to getting free fonts, you can make requests for customized fonts using images and download fonts directly to your computer.
Dafont has thousands of fonts available as of 2015 and also include instructions on how to download the files into your Microsoft Word font folder. Most are free for download, although some authors do request small donations. Other sites, such as Font Squirrel, are marketed for professionals, such as graphic designers, to use in projects and on websites. They include both free and inexpensive fonts for their customers to use.
