Convert ODM to EPUB

It is certainly possible to convert documents from ODM format to EPUB, but you first have to export or convert the ODM document to some common document format like DOCX or RTF, essentially to a format that is accepted in most ebook managers or converters. If the .odm file comes from OpenOffice.org software, you can save it as ODF or other document file type. You can then import the documents into software like Calibre or Hamster ebook converter and export them as EPUB ebooks, finally achieving the ODM to EPUB conversion.

If the .odm file comes from OverDrive, the conversion is probably not possible. The primary challenge in converting ODM to EPUB is DRM protection. DRM restricts how the file can be used and converted, often preventing unauthorized conversions. Additionally, ODM files are not standalone eBooks; they serve as a link to the borrowed content, which is streamed or downloaded via OverDrive. This means the actual content isn't directly stored within the ODM file, complicating the conversion process further.
