Supports: ODT
This tool converts an editable OpenDocument Text file from LibreOffice Writer, Apache OpenOffice or Google Docs into Microsoft Word's .doc binary format. The output is a real, editable Word document — nothing is rasterized or flattened into a picture. But settle one question first, because it decides which page you should be on: .doc is the Word 97–2003 binary format. If your recipient runs any Word released since 2007, they want ODT to DOCX. Choose .doc here when a pre-2007 word processor, a fixed intake form, or a legacy line-of-business system specifically demands the old binary.

.doc and rejects anything newer..doc is far more likely to be fatal..doc is a detour that ends in a "Save As" prompt. Use the ODT to DOCX converter instead..odt onto the page or click "+ Add Files" to browse. Several documents can be queued and converted in one batch; the practical limit on a very large file is upload size and connection speed, not a page count..doc and open it in Word or LibreOffice before you discard the original. Skim page breaks and any complex table first — those are where cross-suite conversions drift. No sign-up, no watermark.We converted a probe ODT — heading styles, a bold run, a footnote, a hyperlink, a bulleted list, a three-column table and pending tracked changes — through the same Word 97 export filter this page uses, then reopened the result. Everything in the "carried over" column below came back intact, including the tracked insertion and deletion, which surprises people who expect revision history to be flattened.
| Feature | Result |
|---|---|
| Body text, headings, character and paragraph styles | Carried over |
| Bulleted and numbered lists | Carried over |
| Tables (standard, within Word's limits) | Carried over |
| Footnotes and endnotes | Carried over |
| Hyperlinks | Carried over |
| Inline images | Carried over |
| Tracked insertions and deletions | Carried over as Word revision marks |
| LibreOffice Basic macros | Not carried over — Word expects VBA, which is a different language |
| Tables wider than 64 columns | Not supported by the Word document model; Microsoft documents this limit |
| Tables placed inside a comment | Text is kept, the row and column structure is lost |
| SmartArt-style diagrams | Arrive as a group of shapes rather than a live diagram |
| Bibliography entries | Converted to plain text |
Anything relying on ODF-specific frame anchoring or unusual page styles can shift by a line or two, which is why step 4 exists. Cross-suite conversion is a re-layout, never a byte-for-byte copy.
It is a genuine, editable Word document. The conversion runs the OpenDocument content through Word's binary export filter, so the result contains live text, paragraph and character styles, lists, tables, footnotes and inline images that you can edit, restyle and re-save in Word or LibreOffice. Nothing is rasterized. If a fixed, non-editable copy is what you actually wanted — a version nobody can reflow by accident — convert with ODT to PDF instead.
Yes. This is the claim most worth testing rather than assuming, so we did: a probe document with one pending insertion and one pending deletion was converted through this exact filter and reopened, and both revisions were still marked and still pending, with their author and timestamp attached. Note that this is specific to the conversion path used here; Microsoft's own documentation warns that when Word saves a document to ODF, all pending changes are accepted instead. If revision history matters, keep the .odt as well.
.doc file inside?It is an OLE compound file — a small filesystem-in-a-file, with named streams for the document text, formatting tables and any embedded objects, which is why every .doc begins with the bytes D0 CF 11 E0 A1 B1 1A E1. Microsoft still publishes and revises the specification as [MS-DOC], most recently in February 2026, so the format is well documented and well supported even though nothing writes it by default any more. The trade-off compared with DOCX's ZIP-of-XML design is repairability: damage in the middle of a compound file is much harder to recover from.
Most documents come through cleanly — text, headings, styles, lists, images, standard tables, headers, footers, footnotes and hyperlinks all map onto Word equivalents. Drift shows up where the two document models genuinely differ: very complex tables, precise vertical spacing, embedded objects created in OpenOffice, and any font that is not installed on the machine that opens the file. Treat the output as a faithful re-layout rather than a photocopy, and give design-sensitive documents a quick read-through before sending them on.
No. The conversion happens on our servers after your file is uploaded, so nothing needs to be installed on your machine and any modern browser works. You only need a word processor afterwards, to open or continue editing the resulting .doc. That also makes this route useful on a locked-down work machine or a phone, where installing an office suite is not an option.
Yes. Every release of Word since 97 opens .doc files, as do current LibreOffice and Apache OpenOffice. Modern Word will usually show a "Compatibility Mode" banner in the title bar, because it disables features the old format cannot store, and it will offer to convert the file up to DOCX. Accepting that is normally the right move once the file has served its legacy purpose.
DOCX, for almost everybody. It is the default of every current Word, it is an open ISO standard, it survives partial corruption better, and it opens in Google Docs, Pages, LibreOffice and Word Online without prompting. The genuine reasons to pick .doc are narrow and specific: a pre-2007 word processor, or a system whose importer only accepts the binary format. If neither applies to you, use ODT to DOCX — and if you already hold a legacy binary you want to modernise, DOC to DOCX goes the other way.
It is uploaded over an encrypted connection, converted on our servers, and then deleted automatically after a few hours. There is no sign-up, no watermark, and files are never shared or made public. If you regularly move documents between the two ecosystems, the ODT converter hub lists the other targets this source format supports, including PDF and the page-image formats.
