ODT to DOCX Converter

Convert ODT to DOCX: What This Guide Covers

You wrote something in LibreOffice or OpenOffice, and now you have to hand it to someone on Microsoft Word. This page converts the .odt into an editable .docx that opens natively in Word 2007 and everything since — and the sections below walk through the handful of features that genuinely can shift on the way across, what we measured surviving the trip, and what to check before you send the file.

How to Convert ODT to DOCX

1. Upload Your ODT File: Drag your .odt onto the page or click "+ Add Files" to browse. Several documents can be queued and each is converted independently; the practical limit on a long illustrated manuscript is upload size and connection speed, not a page count.
2. Confirm the Output Format: The target is already fixed to DOCX on this page, so there is nothing to choose. If you specifically need the legacy Word 97–2003 binary instead, switch to ODT to DOC.
3. Convert: Click Convert. A headless office engine opens the OpenDocument file and re-writes it through Word's Office Open XML export filter, rebuilding your styles, lists, tables, footnotes and images inside Word's own document model.
4. Open and Verify in Word: Download the .docx and open it in Word, Word Online, Google Docs or LibreOffice before you send it on. For a typical letter, report or CV it matches the original; if you used tracked changes, macros or very wide tables, read the walk-through below first. No sign-up, no watermark.

ODT vs DOCX at a Glance

The two formats are far more alike than their reputations suggest — both are ZIP archives full of XML, and the conversion is a re-layout between two similar models rather than a rescue operation.

Walk-through: What We Measured Surviving the Conversion

Rather than repeat the usual "most formatting is preserved", we built a probe document containing a heading style, a bold character run, a footnote, a hyperlink, a bulleted list, a three-column table and two pending tracked changes, and pushed it through the same export filter this page uses. Unzipping the resulting .docx and reading word/document.xml showed the following.

The tracked-changes result is the one worth flagging, because plenty of advice online says the opposite. Microsoft's own documentation warns that when Word saves a file into OpenDocument format, "all changes are accepted" — but that describes Word's ODF filter, which is a different code path from the one used here. Converting in this direction, the revisions came through as live w:ins and w:del marks with author and timestamp attached. Even so, if the revision history is legally or editorially important, keep the original .odt as well; a conversion is never the place to store your only copy of anything.

Common Problems and How to Fix Them

• "My macros are gone." OpenDocument stores LibreOffice Basic; Word runs VBA, and a plain .docx cannot hold macros at all — that is what the separate .docm extension exists for. Keep the .odt for the automation logic and rebuild it in Word if you need it there.
• "A wide table got clipped." Microsoft documents that tables with more than 64 columns are not supported in this conversion. Split anything wider into two tables before converting, or restructure it as a spreadsheet.
• "A table inside a comment lost its grid." Also documented by Microsoft: the contents of a table in a comment are kept but the row and column structure is not. Move tabular data into the document body.
• "My SmartArt-style diagram isn't editable any more." Diagrams arrive as a group of shapes. They display correctly and can be moved and resized, but they are no longer a live diagram object.
• "My bibliography turned into ordinary text." Bibliography entries are converted to plain text, so the field that regenerated them is gone. Rebuild the bibliography in Word if you need it to stay live.
• "Fonts look different." The layout engine substitutes any font it does not have. Stick to widely available families, or check the result and re-apply an installed font before distributing.

When This Doesn't Work

Most ODT files convert with high fidelity, so this section is about the edges. A document that is encrypted with an open password cannot be converted at all — there is nowhere to supply the password, so remove the protection in LibreOffice first. Digital signatures do not survive either; the signed bytes stop existing the moment the file is re-written, so re-sign the DOCX afterwards if that matters. Heavily designed layouts that lean on ODF-specific frame anchoring or unusual page styles usually need a few minutes of cleanup in Word. And if what you actually want is a fixed copy nobody can reflow, convert with ODT to PDF instead of DOCX. Still holding a legacy binary .doc? DOC to DOCX modernises it in one step.

Frequently Asked Questions

Will I lose formatting when I convert ODT to DOCX?

Mostly no, and for a normal letter, report or CV the answer is genuinely "it looks the same". Both formats store the same kinds of content as ZIP-packed XML, so text, paragraph and character styles, lists, images, standard tables, headers and footers, footnotes and hyperlinks all map across cleanly — we verified each of those on a probe document. The exceptions are narrow and listed above: macros, tables over 64 columns, tables inside comments, live SmartArt and bibliography fields. Everything else is a re-layout rather than a rewrite.

What is the actual difference between ODT and DOCX?

Less than the file extensions suggest. ODT is the OpenDocument Text format defined by OASIS and ratified by ISO/IEC as 26300, used by default in LibreOffice and Apache OpenOffice; DOCX is Microsoft's Office Open XML, standardised as ECMA-376 and ISO/IEC 29500, used by default in Word since 2007. Both are ZIP archives of XML parts — ODT keeps its body in content.xml, DOCX in word/document.xml. The practical difference is which application treats each as native, plus a small set of features that have no exact counterpart on the other side.

Which versions of Word can open the DOCX I get?

Every release from Word 2007 onward opens it natively, as do Word for Microsoft 365, Word Online, Google Docs, Apple Pages and current LibreOffice. Word 2003 and earlier used the binary .doc format and need an add-in to read DOCX at all. If you are sending the file to a recipient whose software you cannot ask about, DOCX is still the safest single choice — and if you know for a fact they are on something pre-2007, use ODT to DOC.

Do tracked changes and comments come through?

Tracked changes do: on our probe document a pending insertion and a pending deletion both arrived as live Word revision marks, unaccepted, with author and date. Comments come through as comments, with one documented caveat — if a comment contains a table, the text is kept but the table's structure is not. The advice you may have read that "converting accepts all changes" comes from Microsoft's description of Word saving into ODF, which is the opposite direction and a different filter.

Do I need LibreOffice or Word installed to do the conversion?

No. Your file is uploaded over an encrypted connection and converted on our servers, so nothing has to be installed locally and any modern browser works — including on a locked-down work machine or a phone. You only need a word processor afterwards if you want to keep editing the result. The uploaded ODT is deleted automatically after a few hours.

Why convert to DOCX instead of just sending the ODT?

Because DOCX is the assumed format almost everywhere outside the open-source world: workplaces, schools, government portals, hiring systems and applicant-tracking software generally expect Word. Sending DOCX means collaborators can open, comment and track-change without a compatibility prompt, and automated intake systems will not reject the upload. If everyone you share with is on LibreOffice or OpenOffice, keeping ODT is perfectly sensible — convert only when a recipient or a system needs Word.

Are images and tables preserved from my ODT?

Yes. Inline images are re-embedded in the DOCX package and standard tables are rebuilt as Word table structures, which we confirmed by inspecting the output XML of the probe document. The limits are Word's own rather than the converter's: no more than 64 columns per table, and no table structure inside a comment. Very large photographs are carried across as-is, so a picture-heavy ODT produces a picture-heavy DOCX.

What happens to my files after the conversion?

Your ODT is uploaded over an encrypted connection, converted on our servers, and deleted automatically after a few hours, along with the DOCX we generated. There is no sign-up, no watermark, and nothing is shared or made public. If you have a batch of documents to move between the two ecosystems, the ODT converter hub lists the other targets available from this source format.
