They sell an estimated 60-80% of all digital books. This matters because, as you may have guessed, Amazon is the biggest retailer of eBooks. Instead, Amazon uses a proprietary format called AZW3 (formerly, MOBI). Without a doubt, ePub is the file format you should use to publish your eBook.ĮPub is the most widely used eBook format, and it’s a powerful platform.īut just because ePub is the main eBook format doesn’t mean it’s the only one you’ll ever need.ĮPub files don’t work on Amazon Kindle devices. Thanks in advance.Before I explain exactly how to convert your ePub files to MOBI/AZW3 files, let me first make something very clear: I am sorry if these are noob questions but I would really appreciate some help on the proper settings to use for converting epub to azw3. The second is the AZW3, where the letter becomes much smaller. The first one is the epub, with a much larger dropcap letter. All the AZW3 books I converted have really large line spaces.Ģ. It only shows when the books are in my kindle.

Is this normal? The line spacing problem does not show when I view the azw3 format using Calibre's viewer.

(I did not fool around with these too much since I am not sure what to do - forgive my being a noob)įor structure detection, everything is turned off. Then I save and convert to azw3 using Calibre. I tweak the epub first using sigil, making very minor changes such as 5pt left and right margins, et cetera. I read in other posts that the epub to azw3 conversion should yield good results, so I am wondering if there is something wrong with my settings. However, I noticed that there were some formatting problems. I converted a number of books from epub to azw3 after upgrading my kindle keyboard to the new version that reads the K8 format.
