Custom Font in Site Title

Ok, here is the problem.

I have maded my Own WordPress Theme, so I added custom Font in Site Name. The problem is in that, that only I see custom font style, everybody else that dont have that font installed see deafult one, is there any chance for me to upload that font somewhere in wordpress folder, so that every visitor can see right font style?

Site is https://www.jugosistem.com
