In order to side-load an ebook file that you did not buy in the Kindle Store onto your Kindle, such as a reader magnet or advanced reader copy, you still had to have a MOBI file. This was huge news, as the MOBI file had been a huge staple of the KDP ebook-uploading process. Later, in June 2021, Amazon sent out emails to authors letting them know that when uploading new and updated books to KDP, they would not be using MOBI files, and instead recommended EPUB.

It was at this point that Amazon stated, “We recommend using EPUB format for publishing new books and updating previously published titles.” Our first inclination that Amazon KDP was phasing out the MOBI file and introducing the EPUB came in November 2020.
