title_body: How to generate Kindle AZK on the command line from mobi/epub? I'm trying to generate an AZK file from the command line.
  
  I need an AZK file because I need to test my Kindle books on iOS devices. These books are in Japanese, which currently is not supported for Enhanced Typesetting, so I need to sideload an AZK file. It's a pain to generate this in Kindle Previewer each time, so I want to automate the process.
  
  The source file is an epub.
  
  I convert the epub with Kindle Previewer 3 via the command line:
  
  kindlepreviewer myfile.epub -convert -showpreview
  
  This will create a mobi from the epub and then launch Kindle Previewer.  From Kindle Previewer, I can then go to File->Export and output an AZK-- this is the part I want to automate.
  
  It seems there was a tool called Gozak for doing this but it's not available anymore.
  
  I tried running azkcreator via the path in MacOS but it just segfaults:
  
  ➜  ~ /Applications/Kindle\ Previewer\ 3.app/Contents/MacOS/lib/azkcreator
  [1]    18208 segmentation fault  /Applications/Kindle\ Previewer\ 3.app/Contents/MacOS/lib/azkcreator
  
  
  So, my guess is that there is no way to create an AZK file from the command line at the moment-- but I hope someone can prove me wrong!
upvoted_answer: I’m not sure you can generate an AZK from the command line. From https://wiki.mobileread.com/wiki/KindleGen
  
  
    Note that Kindle Previewer is currently the only way to generate AZK files for iOS use.
  
  
  Not the answer you seek, but an answer.
