About Converting ODT to DOCX

ODT (OpenDocument Text) is the native document format of LibreOffice, OpenOffice and other open-source suites. While ODT is a fine open standard, many workplaces, universities and clients run Microsoft Word and expect a .docx file. Converting ODT to DOCX bridges that gap without forcing anyone to install extra software.

PrivConvert maps OpenDocument styles onto their Word equivalents using the LibreOffice engine, so paragraph styles, tables, headers, footers and images come across intact. Processing is entirely in memory and your file is wiped the moment the DOCX is generated.

Common use cases

  • Sending a LibreOffice document to a colleague or client who only uses Microsoft Word
  • Submitting an assignment to a portal that accepts .docx but not .odt
  • Collaborating in Microsoft 365 on a document originally authored in LibreOffice
  • Standardising mixed open-source and Microsoft document workflows
  • Preparing an ODT for tools and services that only ingest Word format

Tips for best results

  • Custom ODT paragraph and character styles map to the nearest Word style; spot-check a heading-heavy document after converting.
  • Fonts that exist only on Linux may substitute on Windows — stick to widely available fonts for pixel-perfect results.
  • Footnotes, endnotes and tables of contents are preserved and remain updatable in Word.
  • If you only need to view the file, exporting to PDF avoids any style-mapping differences entirely.

Frequently Asked Questions

How do I convert ODT to DOCX?
Upload your ODT file above, complete the quick security check, and your DOCX file is generated instantly. No software install and no sign-up required.
Is it free and private?
Yes. Every conversion is completely free and runs entirely in memory - your file is never written to disk and is deleted the moment your download is ready.
Will my layout and formatting survive?
Conversion is handled by the LibreOffice engine, which preserves text, tables, fonts and layout with high fidelity across formats.
Is there a file size limit?
You can convert files up to 250 MB each, and batch-convert up to 20 files at once.
Can Microsoft Word open ODT directly?
Recent versions of Word can open ODT, but support is partial and formatting often shifts. Converting to native DOCX gives a far more reliable result, especially for complex layouts.

Yes. The output is a fully editable Word document — you can continue writing, restyle, and use track changes exactly as with any DOCX.
