Choose fonts for epub3

How do I filter fonts that are possible to use for epub3? I can't find a way of knowing which fonts are OTF. I have written a book in Poppins and Garmond Premier, which works fin for printing but not for epub, so I need to replace them.

I want to use the fonts in an Epub3 in fixed format and Epub3 only allow OTF and WOFF fonts. So I want to see font type in Adobe Fonts and I can't find how to do that. Do you know how to see font type in Adobe fonts?

I know that Poppins is an TTF font since I use it in my printed book, but the Epub3 validation tool does not allow TTF-fonts.


If you have to upload separate font files Adobe Fonts won't work for such purposes since it doesn't store individual font files that are visible in the computer's file system. The data is somewhat hidden. You won't find things like OTF files in any file folders using Windows File Explorer or the Finder on a Mac.

 

The Adobe Fonts web site doesn't display font formats other than static, variable and color. When I'm using Adobe's desktop applications, such as Illustrator, any fonts synced via Adobe Fonts will typically have an OpenType symbol listed next to them in the font menu. I see the same thing in some rival graphics applications.

 

There are third party applications, such as TransType 4, than can convert TrueType fonts into OpenType format.

 

I'm not an expert on EPUB 3 or coding references to fonts in web pages. I don't know if the methods people use to code Adobe Fonts into web sites will work with EPUB 3. Google Fonts offers embed code for HTML at its site. Does it not point to WOFF web font files?

Which computing platform are you using (Mac or Windows) and how are you viewing the font files? On the Windows platform the Windows\Fonts folder really likes to hide many important details, such as font formats. It often takes looking at copies of the font files stored in other folders where the file name suffix (such as .otf) can be easily seen.

 

In Adobe's applications static OpenType fonts will usually have the OpenType "O" icon listed next to the font name. Variable Fonts are technically "OpenType" but may have different file name suffixes such as TTV or OTTV.

I use Mac and Creative Cloud where fonts are included but the font type does not show in the list of installed fonts.

As far as I can tell all the static fonts available via Adobe Fonts are in OpenType format. Are you going to be embedding the fonts in a PDF?
