There are three main ways to add fonts to your Monotype Connect font libraries.
1. Right Click Menu:
- Select your library or set that you wish to add the fonts to.
- Right click anywhere on the name of the library and choose "Upload Fonts to Library"
- From within the MacOS Finder or Windows Explorer, navigate to the location where your fonts reside, select the font(s) you want to add then click Open (note: you cannot add fonts from the default system font locations)
2. Drag and Drop
Drag one or more fonts to any library to add the fonts to that specific library and to the All Fonts collection.
Drag one or more fonts to any set to add the fonts to that specific set, the set’s parent library, and to the All Fonts collection.
Drag one or more fonts to All Fonts to make the fonts available to other Administrators to add to any library.
3. Upload Icon 
- Click on the upload icon to add fonts to the current library. Select the font files to upload and click Open.
- If you don’t have the Monotype Connect desktop app installed on the same system, then you won’t be able to add, remove, or activate fonts using the Monotype Connect web app.
