What I like best is how simple Epubor makes it to get ebooks into the format I need. I add the books, pick the output format (EPUB, MOBI, AZW3 or PDF), and it takes care of the rest in a couple of clicks, so I can read on whichever device or app suits me. The interface is clean and uncluttered, it can convert several books in one go, and the converted files come out clean and readable. It just works without me having to fiddle with settings.

Honestly, there isn't much to dislike. The main thing is that the full version needs a paid licence and the free trial is quite limited, so you have to buy it before you can really put it to use. That said, for what it does, I think it's well worth it. Review collected by and hosted on G2.com.
