About formats

MOBI is an ebook format originally developed by Mobipocket SA, a French company founded in 2000 that was later acquired by Amazon in 2005. The format builds on the PalmDOC/PDB container structure, adding support for HTML-based content markup, embedded images, a DRM layer, and a JavaScript subset for limited interactivity. MOBI files use a record-based database architecture inherited from Palm OS, with a header structure containing metadata like title, author, publisher, and language followed by compressed HTML content records. The format became the foundation of Amazon's early Kindle ecosystem — the original AZW format used on first-generation Kindles was essentially MOBI with Amazon's own DRM wrapper. MOBI supports reflowable text with basic formatting including bold, italic, headings, lists, and tables, as well as internal hyperlinks and a built-in table of contents. One advantage is broad device compatibility: MOBI files are recognized by Kindle devices and apps spanning over a decade of hardware, as well as numerous third-party readers on desktop and mobile platforms. The format's lightweight structure is another strength — even long novels produce compact files that load quickly on modest hardware. While Amazon has since moved to the more capable AZW3/KF8 format for new publishing, MOBI remains widely circulated in existing ebook libraries and continues to be produced by conversion tools like Calibre for maximum Kindle compatibility.

ODT (OpenDocument Text) is the word processing format defined by the OpenDocument Format (ODF) standard, developed by the OASIS technical committee and first published as ODF 1.0 on May 1, 2005, later adopted as international standard ISO/IEC 26300. An ODT file is a ZIP archive containing XML documents that describe text content, formatting styles, metadata, and settings using a vendor-neutral, royalty-free specification. The document body resides in content.xml with styling rules in styles.xml, while embedded images, fonts, and other resources are stored alongside in the package. The format supports rich word processing features including paragraph and character styles, tables, footnotes, tracked changes, table of contents generation, bibliography management, mail merge fields, and embedded vector and raster graphics. ODT serves as the native format for LibreOffice Writer, Apache OpenOffice Writer, and Calligra Words, and can be imported by Microsoft Word, Google Docs, and other commercial tools. One advantage is vendor independence — ODT is governed by an open standard rather than a single company, ensuring long-term document accessibility free from proprietary lock-in. This makes ODT particularly important for government agencies, educational institutions, and organizations with archival mandates. The XML-based architecture provides another strength, enabling programmatic document generation and processing using standard tools in any programming language.

Frequently Asked Questions

Why convert MOBI to ODT?

ODT is the open-source document standard for LibreOffice and OpenOffice — converting from MOBI lets you edit ebook text in free word processors.

How do I open an ODT file?

LibreOffice Writer, Apache OpenOffice, Google Docs, and Microsoft Word (2007+) all open ODT documents without any additional plugins.

Does the conversion preserve the ebook layout?

Text, paragraphs, and headings carry over from MOBI. The document will be formatted for editing rather than mimicking an ebook reader layout.
