    The details

    What happens when you convert between document formats

    The OpenDocument text format. LibreOffice's own, fully open and fully documented. The document is opened in a layout engine and re-saved in the target format, mapping each style onto the closest equivalent in the new format. The result is a microsoft word's modern document format. xml files inside a zip archive, produced entirely inside your browser.

    What survives

    • The text and the paragraph structure
    • Most formatting: fonts, sizes, colours, alignment, lists and tables
    • Embedded images

    What changes

    • Styles that have no equivalent are approximated
    • The file may gain or lose features the target format does not support

    Where it goes wrong

    • Styles are usually mapped by name, so renaming a style before converting can lose the mapping
    • The target format may not support the same page size or margins

    Why anyone would do this

    Different teams use different formats, and the content should not be held hostage by that.

    About the format

    The OpenDocument text format.

    A ZIP archive with a standard XML document inside, following the OpenDocument format specification that ISO standardised.

    Where it is good
    • A published, royalty-free standard rather than a company format
    • Can be opened and edited without any permission or licence
    • Round-trips cleanly through LibreOffice, Word and Google Docs
    Where it falls short
    • Microsoft Office does not open it natively
    • Some upload portals reject it
    • Not as common as DOCX, so few people have a reader installed
    You will find it on
    LibreOffice, OpenOffice, European government offices

    The thing people miss

    ODT and DOCX are both ZIP archives of XML — the difference is mostly the naming rules inside.

    About the target

    Microsoft Word's modern document format.

    A zip archive containing a Word document, its styles, any embedded images, and a list of relationships between them.

    • Holds styles, tracked changes, comments, tables and images properly
    • Compresses well because the XML inside is highly repetitive
    • Opens in Word, Google Docs, LibreOffice and Pages
