Short answer: upload the .odt file directly. OpenDocument Text, LibreOffice's and OpenOffice's native format, carries the same kind of real heading structure a Word document does, so it converts to a reflowable EPUB the same reliable way, free, with no account.
What ODT is
OpenDocument Text is the open, standardized format behind LibreOffice Writer and OpenOffice Writer, and the required format for official documents in a number of governments and organizations. Functionally it does the same job as DOCX, it's just produced by a different, open-source suite of office software rather than Microsoft Word.
Why it converts as reliably as DOCX
An ODT file is genuinely structured XML underneath, the same way a DOCX file is. A heading typed with Writer's Heading 1 or Heading 2 style is tagged as a heading in the file itself, which is exactly what a converter needs to build real chapters and a table of contents. Because of that, ODT skips this converter's PDF-only machinery entirely, no scan detection, no OCR, no header/footer cleanup, and goes straight to producing the EPUB.
The same honest caveat applies as with DOCX: chapter detection depends on the document actually using heading styles, not just larger bolded text standing in for one.
Steps
- Go to the converter and drop your .odt file in.
- Nothing else to configure, ODT has no scan/OCR/Pro decision to make.
- Download the finished
.epubonce it's ready. - Read it on a Kindle, Kobo, Apple Books, or any EPUB reader.
