Convert Word to ODT
Ethical Tube's free Word to ODT converter turns Word documents into ODT, the open document format of LibreOffice, using LibreOffice, the open-source office suite. It runs entirely in your browser, so your documents are never uploaded, and it's free with no sign-up or watermark.

Word and ODT at a glance
What is a Word file?
DOCX is the document format Microsoft Word has used since 2007. It stores editable text with styles, tables, images, comments, and tracked changes, and it's what most people mean when they ask for a Word file. It opens in Microsoft Word, Google Docs, Apple Pages, LibreOffice Writer, WPS Office, and the Word app on phones.
What is an ODT file?
ODT is the OpenDocument text format, an open international standard (ISO/IEC 26300) and the default in LibreOffice Writer and Apache OpenOffice. Some governments require it for public documents. Word and Google Docs open ODT files, but complex formatting can shift. It opens in LibreOffice Writer, Apache OpenOffice, Microsoft Word, and Google Docs.
Good to know
What changes when you convert Word to ODT
- Text, formatting, tables, and images carry over to ODT.
- Moving between OpenDocument and Microsoft formats can shift complex layouts, so check documents with heavy formatting.
- The first conversion downloads LibreOffice compiled to WebAssembly (77 MB). It's cached, so later visits start quickly.
- Chinese, Japanese, and Korean text may appear in a fallback font.
- Password-protected documents can't be converted.
- It works best on a computer, because LibreOffice needs a lot of memory.
FAQ
Questions, answered
Is this Word to ODT converter free?
Yes. It's completely free, with no sign-up, no watermark, and no limit on how many files you convert. It costs Ethical Tube nothing to run, because the conversion happens on your own device rather than on a server.
Are my files uploaded anywhere?
No. The conversion runs inside your browser with LibreOffice compiled to WebAssembly, so your files never leave your device. Once the page and the engine have loaded, it even works offline.
Why is there a download the first time?
The conversion uses LibreOffice, the open-source office suite, compiled to run inside your browser. It's about 77 MB, downloads once from Ethical Tube's own server, and is cached for next time. Your documents are never uploaded.
Can I convert several Word files at once?
Yes. Add as many as you like. They're converted one after another, and you can download each ODT file as soon as it's ready or all of them in one ZIP file.
Does it work on iPhone, Android, Mac, and Windows?
It works in Chrome, Edge, Firefox, and Safari, but it's built for computers. LibreOffice needs about 1 GB of memory, which many phones can't spare.
What can open an ODT file?
LibreOffice Writer, Apache OpenOffice, Microsoft Word, and Google Docs.
Is there a file size limit?
There's no upload limit because nothing is uploaded. The practical limit is your device's memory: everyday files are fine, and most computers handle documents with hundreds of pages.
