How to convert ODT to DOCX

  1. Add your ODT documents

    Drop ODT files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.

  2. DOCX is already chosen

    Press Convert and confirm the upload. The file is sent to the ToAny conversion server, converted to DOCX and removed afterwards.

  3. Download

    Save the DOCX, or download everything as one ZIP if you converted several files.

Why ToAny

  • Honest about uploads

    Browsers cannot convert ODT to DOCX reliably, so this pair runs on our server. You are asked before anything is sent, and the page says so plainly.

  • Removed afterwards

    The uploaded file and the result are deleted once the conversion has finished. Nobody looks at them and they are not used for anything else.

  • No account

    No sign-up, no email address and no watermark on the result.

ODT to DOCX: what to expect

ODT is unfamiliar to many recipients and does not always open cleanly in Word. DOCX can be edited in Word, Google Docs, Pages and LibreOffice. ODT is at home in documents in open-source office suites; DOCX is the usual choice for documents that will be edited again.

ODT vs DOCX

ODT

OpenDocument text

ODT is the open-standard document format used by LibreOffice Writer and OpenOffice. Word and Google Docs can open it, though complex formatting does not always survive the trip.

DOCX

Word document

DOCX is the format Microsoft Word has saved by default since Office 2007. Inside it is a ZIP archive of XML files describing text, styles and images. Layout can shift between Word, Google Docs and LibreOffice because each lays the text out itself.

Questions

Is my ODT file uploaded?

Yes, for this conversion. Browsers cannot convert ODT to DOCX reliably, so after you confirm, the file is uploaded over an encrypted connection to the ToAny conversion server, converted automatically and deleted once the conversion has finished. Most other conversions on ToAny run in your browser and upload nothing.

Is anything lost when converting ODT to DOCX?

Text is kept. Formatting carries over only as far as DOCX supports it.

Can I convert several ODT files at once?

Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.

How do I convert ODT to DOCX on Windows, Mac, iPhone or Android?

The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the ODT file, press Convert and save the DOCX. There is nothing to install.

Is there a file size limit?

Yes. Files sent to the conversion server are capped in size, and the page tells you when a file is too large to upload.
