Sumatra PDF is a PDF, ePub, MOBI, CHM, XPS, DjVu, CBZ, CBR reader for Windows

I can't change font

I have tried it all, i swear, 15 different types of fonts, reinstalling Sumatra, changing UseFixedPageUI, changing the language, using fonts that didn’t have space in between. I have read every comment about this topic in the site, every post, and still it does not work. (using the installer for 64-win)

You can’t change the font of what?

The PDF text font, basically “FontName” does nothing to me.

It’s not possible to change the font of a PDF file.

FontName option is only for epub/mobi etc. files.

The docs are pretty specific about this (Customizing SumatraPDF 3.2):

customization options for eBooks (EPUB, Mobi, FictionBook) UI

Thanks man, i am dumb.
