ODT to EPUB 2 Converter
Processing entirely on your device — large files may take a moment.
ODT is the OpenDocument word-processing format — the LibreOffice Writer native file, defined by an open ISO standard instead of a vendor. It carries full document semantics: styles, headers, footnotes, tables, images. Convert EPUB 2 files like EPUB — the reader handles both editions.
Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.

About the ODT format
ODT is the OpenDocument word-processing format — LibreOffice Writer's native file, standardized as ISO/IEC 26300 and required by many public-sector IT policies precisely because no vendor owns it. Like DOCX it is a zip of XML, and it carries the full document semantics: styles, headers, footnotes, tables, embedded images.
Word opens ODT fine these days, and LibreOffice opens DOCX — yet conversions between the two still trip over macros, form fields and exotic formatting. Sending content into ODT makes it future-proof under an open standard; pulling ODT into DOCX or EPUB moves it into mainstream pipelines.
+ Strengths
- ✓Open ISO standard, vendor-neutral by law in some sectors
- ✓Full document semantics: styles, footnotes, tables
- ✓Native to the free LibreOffice suite
! Limitations
- −Less common in business hand-offs than DOCX
- −Macros and form fields may not survive conversion
- −Mobile office apps sometimes render it imperfectly
About the EPUB 2 format
EPUB is the open standard of e-books (IDPF, now W3C): a ZIP package of XHTML chapters, CSS styling and metadata, rendered reflowably on any screen size. Text re-wraps to your phone, your e-reader and your monitor; font size, margins and typography belong to the reader, not the publisher. EPUB3 adds fixed-layout support, media overlays (read-aloud) and rich semantics.
It is the universal format of every ebook platform except Kindle (Amazon accepts EPUB uploads since 2022 but converts internally). DRM is optional — many EPUBs are open, library books use Adobe ADE encryption. For text-centric books it is the right long-term choice; heavily designed print layouts survive conversion imperfectly.
+ Strengths
- ✓Reflows to any screen — the point of e-books
- ✓Open standard, future-proof, tool-rich
- ✓Accepted by every store and reader app
! Limitations
- −Kindle devices still need conversion to Kindle formats
- −Complex print layouts translate imperfectly
- −DRM variants need specific readers

Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for ODT to EPUB 2?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
