If you run into problems, the developers and fellow users are much willing to help, in the discussion forum you can basically find anything that is hindering you from having a good user experience. Sumatra also has a portable version so you can put it into your USB drive and don’t have to download the software again if you have changed devices. One downside is that in Sumatra you can’t change the font size easily, you’ll need to go extra miles and customize the Font Size in the Advanced Options. Everything you need is listed and organized in the main interface, but you can discover more in the Advanced Options. The aim is to provide a simple and handy reading experience without lengthy and jumbled features/UI. It’s free, open-source, minimalist and light. Unlike its name, Sumatra can not only open PDF files, but also EPUBs and other popular formats like MOBI etc. Platforms: Windows 10, Windows 8, Windows 8.1, Windows Vista and Windows 7.
