Fonts - koreader/koreader GitHub Wiki

KOReader has some built-in fonts, and you can also install your own fonts.

Installing Fonts

You must use .ttf TrueType or .otf OpenType. The .pfb and .pfa formats are also supported. You cannot use .woff, .woff2, .eot, .svg or other font types.

Also, when adding fonts, they can be in many different types (i.e. different file names). Very useful info about which font types (i.e. file names) to use can be found here.

Android

On Android devices, copy the .ttf font file to:

/koreader/fonts/

You may need to create the /fonts/ directory

PocketBook

For each font, make a directory in /applications/koreader/fonts/ and copy the .ttf file(s) there.

Kobo

For each font, make a directory in /.adds/koreader/fonts/ and copy the .ttf file(s) there.

Desktop

To use a custom font on desktop, install the font to your system, then toggle the Use System Fonts option under font settings.
