Supports: DOC
.doc file or click "Upload" — you can also pull it in from Google Drive or Dropbox. Batch is supported, so drop in several DOC files and each one converts on our servers.DOC is the legacy Microsoft Word binary format. From Word 97 through Word 2003, every Word document saved by default as a .doc file — a proprietary, OLE-based Compound File Binary Format (structured storage) that packs text, formatting, and embedded objects into a single binary blob. Word 2007 replaced it as the default with DOCX (Office Open XML), so any .doc file you still have is at least a 2007-era format.
That age is exactly why people convert it. The old binary format is harder for non-Microsoft software to parse reliably, can render inconsistently across modern apps, and is no longer the format most tools expect to receive. Common reasons to convert:
| Property | DOC | DOCX | ODT |
|---|---|---|---|
| Full name | Word Binary File Format | Office Open XML (Word) | OpenDocument Text |
| Default in | Word 97–2003 | Word 2007 onward | LibreOffice / OpenOffice |
| Standard | Proprietary (Microsoft) | ECMA-376 / ISO/IEC 29500 (2008) | OASIS / ISO/IEC 26300 (2006) |
| Internal structure | OLE compound binary | Zipped XML | Zipped XML |
| Typical file size | Largest | Smaller than DOC | Comparable to DOCX |
| Damage recovery | Hard (single binary blob) | Easier (separate XML parts) | Easier (separate XML parts) |
| Best for | Compatibility with very old Word | Current Microsoft / Google / Office workflows | Open-source office suites |
| Your goal | Best output | Editable after? | Notes |
|---|---|---|---|
| Send a final, fixed-layout copy | No | Looks identical everywhere; no Word needed | |
| Modernize the file for editing | DOCX | Yes | Current Office / Google / LibreOffice standard |
| Move to an open-source suite | ODT | Yes | Native to LibreOffice / OpenOffice |
| Publish as an e-book | EPUB / MOBI | Reflows | EPUB is the open standard; MOBI is legacy Kindle |
| Drop a page into a chat or app | JPG / PNG | No (raster) | One image per page |
| Feed a print pipeline | PS | No | PostScript for prepress workflows |
Microsoft Word opens DOC natively and still reads the format despite DOCX being the default since Word 2007. Free options also handle it: Google Docs imports DOC files, LibreOffice Writer and Apache OpenOffice open them, and Word for the web reads them in a browser. Because DOC is a proprietary binary format, non-Microsoft apps occasionally render complex layouts slightly differently — converting to PDF or DOCX first avoids that.
Convert it to DOCX unless you specifically need to hand the file to someone running a pre-2007 version of Word. DOCX is the modern Office Open XML standard: it produces smaller files, recovers better from corruption because the document is stored as separate XML parts inside a zip rather than one binary blob, and is what current Word, Google Docs, and LibreOffice all expect. The only reason to stay on DOC is legacy compatibility.
It shouldn't. PDF is designed to lock layout — fonts, spacing, images, and page breaks are embedded so the document looks identical on any device or printer, without Word installed. In our testing, a multi-page DOC with embedded images and tables converted to a PDF that matched the original page-for-page. If anything shifts, it is usually because the original DOC referenced a font the system doesn't have; the converter substitutes a close match.
ODT is the native OpenDocument text format for LibreOffice and OpenOffice, so it is the cleanest target if you're moving off Microsoft Office. That said, both LibreOffice and OpenOffice open DOC files directly, so you don't strictly need to convert first — opening the DOC and choosing "Save As → ODT" inside the app works too. Converting to DOCX is the more universally compatible choice if the file may also need to open in Microsoft Word later.
DOC itself doesn't compress text, so the words and formatting are preserved exactly. Converting to DOCX or ODT is also lossless for the document content — only the container changes. Converting to PDF embeds the layout faithfully; the one place size and quality trade off is image-heavy documents, where the Compression Type ("Screen" vs "Printer/Prepress") controls how much the embedded images are downsampled. Rendering pages to JPG or PNG is the only conversion that rasterizes text into pixels.
Because DOC is a binary OLE compound format, not plain text. Opening it in Notepad, a code editor, or any app that expects text shows the raw binary — strings of boxes, symbols, and fragments of your words wrapped in structural data. That is not corruption; it just means the file was opened with the wrong kind of program. Open it in Word, Google Docs, or LibreOffice Writer, or convert it to DOCX or PDF, and the text renders normally.
It depends on the target. Converting to DOCX or ODT keeps the editable document model, so comments and tracked revisions carry across into the new word-processor file. Converting to PDF or a page image produces a fixed snapshot of the document as it displays — you keep the visible result, but not an editable revision history. If you need to hand off a file someone will keep reviewing, choose DOCX; if you're distributing a finished read-only copy, PDF is the right target.
Yes. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — they are never shared, made public, or used for anything but your conversion. There's no sign-up and no watermark on the output. If you only need a word count rather than a conversion, the in-browser Word Counter processes text without any upload at all.
