How to Convert an E-Book File
Convert a DRM-free ebook to read in any format and on any device. (Zedcor Wholly Owned/ Images)

The ability to read e-books on any digital device makes e-book very mobile and popular. File conversion of any unsecured, DRM-free book requires using a third-party program, such as Calibre; however, Calibre conversions add additional hidden coding to the files. Also, converting a PDF to EPUB or MOBI for publication is not recommended. Easily convert an EPUB files to MOBI using the Kindle Previewer drag and drop method. Due to its simplicity, Kindle Previewer is the optimal conversion choice for publication, without adding unnecessary coding.

Tips and warnings

  • Calibre supports many formats for conversion, including Word, PDF, EPUB, MOBI, RTF and text.
  • SIGIL is the best program to edit, convert and publish an EPUB to Kindle. It helps retain the original EPUB structure, while letting you directly modify the HTML code.
  • EPUB format may be directly uploaded to the Kindle Direct Publishing service. KDP automatically converts the format to a compatible MOBI file.
  • Never hack into a DRM-protected file. It is illegal and punishable by law.
  • Never convert from PDF to EPUB or MOBI for publication. PDF uses coding that is not compatible with e-reader devices.
  • Calibres' conversions are not always accurate when converting e-books for publication.
