ODT is an OpenDocument Text file format used by word processors such as LibreOffice and OpenOffice. MOBI is an eBook format originally used by Amazon Kindle devices and apps. Converting ODT to MOBI turns a document into a format that is better suited for reading on e-readers.

Why convert odt to mobi

ODT files are ideal for editing and document creation, while MOBI files are optimized for eBook distribution and reading on Kindle-compatible devices. If you want to publish a manuscript, novel, or long-form document for e-readers, MOBI can be a practical output format.

Best software for conversion

The best all-around tool for this conversion is Calibre, a powerful and free eBook manager and converter. It supports importing ODT files and exporting to MOBI with good control over formatting, metadata, and chapter structure. For document-focused workflows, LibreOffice can export to EPUB first, and then Calibre can convert EPUB to MOBI for better results.

How to convert odt to mobi

Using Calibre:

  1. Open Calibre and add your ODT file.
  2. Select the file and choose Convert books.
  3. Set the output format to MOBI.
  4. Adjust metadata, look and feel, and structure if needed.
  5. Click OK to start the conversion.

Using LibreOffice plus Calibre:

  1. Open the ODT file in LibreOffice.
  2. Use File → Export As → Export as EPUB if EPUB export is available, or save as a compatible intermediate format.
  3. Import the EPUB into Calibre.
  4. Choose Convert books and select MOBI as the output.

Conversion tips

  • Use headings in the ODT file to help Calibre create a proper table of contents.
  • Keep formatting simple for the best MOBI output.
  • Check images and embedded objects, since complex layouts may not convert perfectly.
  • Review metadata such as title, author, and cover image before exporting.

Limitations to know

MOBI is an older format and has been largely replaced by AZW3 and EPUB in many workflows. If your target device supports newer formats, consider exporting to EPUB first and using MOBI only when specifically required by an older Kindle device or app.

Recommended workflow

The most reliable workflow is ODT → EPUB → MOBI. This usually preserves structure better than converting directly from ODT to MOBI, especially for documents with chapters, images, or styled headings.
