As a Kindle owner, I regularly have to convert epub files to mobi files. There’s an application called Kindlegen for that. Unfortunately, it doesn’t always work, because some epub files have settings that Kindlegen doesn’t understand, or the file ends up having a strange title.
With some knowledge of epubs you can fix these errors yourself. I’ll look at two problems I ran into:
- The author name or book title is not correct.
- The language isn’t set.
