How to Convert Word to ODT

Someone sends you a .docx. You use LibreOffice, or your organisation standardised on OpenDocument years ago, or a government portal will only accept .odt. Converting is a few seconds of work — but it is worth understanding what you are actually trading.

What ODT is, and why it exists

ODT is OpenDocument Text, the word processing format of the OpenDocument standard. Like .docx it is a zip archive of XML files describing your content and styles. The difference is governance: OpenDocument is an open ISO standard maintained by a vendor-neutral body, not a format controlled by a single company.

That distinction matters in specific places:

• Public sector. Several governments mandate open document formats for records and public submissions, precisely so a citizen never needs to buy particular software to read them.
• Long-term archives. A fully published, freely implementable standard is a safer bet for documents that must open in twenty years.
• Free software workflows.LibreOffice, OpenOffice, Collabora and friends use ODT natively. Working in their own format avoids a round trip through somebody else’s.

Convert Word to ODT, step by step

1. Open the converter. Go to Word to ODT. It accepts .docx and legacy .doc.
2. Convert. LibreOffice on our server opens the document and saves it as OpenDocument Text — the same engine that would do it on your desktop.
3. Download the .odt and open it in LibreOffice, OpenOffice or any OpenDocument-capable editor.

What survives the conversion

Almost everything, and better than most people expect. Both formats describe the same kind of object — a flowing, styled, editable document — so this is a translation between two similar languages rather than a flattening.

Comes through reliably: text and paragraph formatting, headings and named styles, bulleted and numbered lists, tables, images, hyperlinks, footnotes and endnotes, headers and footers, page setup, and the table of contents.

Worth checking: heavily custom Word features. Content controls, some SmartArt, certain field codes, complex text-box layouts and macros are Word-specific and may simplify or disappear. Fonts are not embedded either — if the document uses a font your machine lacks, a substitute is used and line breaks shift slightly.

For ordinary letters, reports, essays and CVs, the result is usually indistinguishable. For a heavily designed template, open it and page through before you rely on it.

The round-trip warning

Converting back and forth repeatedly — DOCX to ODT, edit, back to DOCX, edit, back again — accumulates small drifts. Each conversion re-expresses your styles in the other format’s vocabulary, and the approximations pile up over time.

So convert once and then work in the new format, rather than treating conversion as a daily commute. If you and a collaborator genuinely need different formats, agree on one as the master and send PDFs for review — a PDF cannot drift because nobody is editing it.

Which direction do you actually need?

• Received a .docx, work in LibreOffice → this tool.
• Received an .odt, need to send it to a Word user → ODT to Word.
• Just need it read, not edited → ODT to PDF or Word to PDF. Sending a PDF sidesteps the whole format question and guarantees everyone sees the same pages.
• Only want the words → Word to Text.

Worth knowing: LibreOffice opens .docx files perfectly well without any conversion. Convert when you need the file to be an ODT — for a submission requirement, an archive policy, or a toolchain that expects OpenDocument — not merely to read it.

Is it private and free?

Translating between two document formats faithfully needs a real office engine, so this converter runs on our secure server rather than in your browser. Your file is uploaded over an encrypted HTTPS connection, converted in an isolated workspace, and deleted automatically the moment the ODT is sent back— nothing stored, logged or shared. Free: no watermark, no sign-up, no daily limit, files up to 100 MB.

Frequently asked questions

Can Microsoft Word open ODT files? Yes. Word has supported OpenDocument for many years — you can open and save .odt directly, though the same conversion caveats apply in that direction too.

Will my tracked changes and comments survive? Usually yes — both formats support them. Review them in the converted file before relying on it, and consider accepting or rejecting outstanding changes before converting.

What about macros? They do not carry over. Word macros are VBA; LibreOffice uses its own Basic. A macro-driven document needs its automation rebuilt, not converted.

Does the file size change? Slightly, in either direction. Both formats are zipped XML, so they land in the same ballpark.

Can I convert an old .doc file? Yes, .doc is accepted. If you have an archive of them, running DOC to DOCX is a reasonable modernisation step in its own right.

Is ODT better than DOCX? Neither is better in the abstract. ODT wins on openness and archival confidence; DOCX wins on ubiquity in offices. Pick the one your recipients and your obligations require.
