How to convert epub to azw2 file

As far as we know, It is not possible to convert epub to azw2, simply due the fact that .azw2 files are not the ebooks, but active content apps for Kindle, which means no epub to azw2 conversion is possible. If you need to export your EPUB ebooks to Amazon format, you have either export it to AZW3 or Mobi format, which are the only formats compatible with Amazon Kindle.

In a word, direct epub to azw2 conversion is not possible.
So don't expect any so-called epub to azw2 converter or epub to azw2 free online conversion tool available.
