Please recommend the best EPUB to AZW3 converter for Windows 11

Sometimes, when you convert EPUB to AZW3 on Windows computer, the formatting goes all wonky. You might end up with weird margins, missing images, or garbled text. The EPUB format is pretty flexible, but AZW3 is stricter.  Before conversion, check your EPUB in an e-reader app to see how it looks. If it's messed up there, it might get worse during conversion.

Now, if you want a Microsoft-centric solution, don't forget about the built-in features of Word. While it doesn’t directly convert to AZW3, you could technically use Word to open and edit your EPUB files if they're in the right format and then save them as other formats for conversion. But for a straightforward solution, going with Calibre or Epubor would definitely save you some headaches. Give them a shot, and happy reading!
