Other APNX conversions

Conversion of apnx files to azw3 file format

Although both .apnx to .azw3 files are used by Amazon Kindle, it is not possible to convert one to another simply due the fact that these files do not contain similar data, i.e .apnx file is but an index, whilst .azw3 is the actual ebook. You can only convert two ebooks, so you will need a different source, which means apnx to azw3 conversion is not feasible.
