Convert DOC to DOCX.
Upgrade an old Word 97-2003 document to the modern DOCX format that current Word, Google Docs and phones expect.
Bring an old document up to date
Archives, legal templates and files from older offices are often still in DOC. Converting gives you a file that opens without compatibility mode and works with track changes, comments and cloud editing.
What carries across
Paragraph and character styles, tables, headers and footers, lists, images and page setup all carry across. Very old documents with unusual embedded objects may need a quick check.
Size change
DOCX is a compressed package, so the converted file is usually smaller than the DOC.

Common questions
Is it free?+
Yes. Convert DOC to DOCX free. No signup and no watermark. Free covers 10 server conversions a day, up to 100 MB a file. Pro removes the daily limit and raises the file limit to 2 GB.
Is my file private?+
Your file is uploaded to a private bucket, converted on our own engine, and auto-deleted after 1 hour. It is never sent to a third-party converter.
Why upgrade from DOC?+
DOC is a binary format from Word 97 to 2003. DOCX is smaller, more robust against corruption, and is the format modern tools and online services handle best.
Are macros kept?+
No. DOCX cannot hold macros by design. If the document relies on macros, it would need the macro-enabled DOCM format in Word.
