HOW IT WORKS
Three steps, no account, nothing to install.
01
Upload your DOC file
Drag and drop or upload a Word 97-2003 or Word 95 .doc file. Confluence and Jira 'Export to Word' files work too.
02
Convert to DOCX
Keep DOCX as the output format and start the conversion. The document is rewritten in the Office Open XML format.
03
Download the DOCX
Download a .docx that opens in current Word, Google Docs and Pages.
DOC
DOC is the binary Microsoft Word format of Word 97 to 2003, and older Word 95 files use the same extension. Archives, templates and older document systems still hold many .doc files, and Confluence and Jira name their 'Export to Word' files .doc as well.
DOCX
DOCX is the Microsoft Word document format used since Word 2007, based on Office Open XML. It supports formatted text, tables, images, headers, footers, comments, and other word-processing features, and opens in Word, Google Docs, Pages and LibreOffice.
FILE FORMATS
SOURCE
DOC is the binary Word format used from Word 97 until Word 2007 replaced it with DOCX. Old letters, contracts, CVs and archives are still full of .doc files, and some government and legal systems still ask for them. Every Word version opens DOC, but in Compatibility Mode.
TARGET
Word switched to DOCX with Office 2007. A DOCX is a ZIP of XML files describing text, styles, tables, images, comments and tracked changes, standardized as ISO Office Open XML. It is the default exchange format for editable documents, accepted by Word, Google Docs, Pages, LibreOffice and most online forms.

USE CASES
Practical workflows where DOC to DOCX conversion is useful.
Edit old files without compatibility mode
Word opens .doc files in compatibility mode. The .docx opens as a normal document, with current Word features available.
Open old documents in Google Docs or Pages
The converted .docx opens in Google Docs, Pages and current Word with its text, tables and pictures.
Modernize a document archive
Convert legacy .doc files to .docx before moving them to SharePoint, OneDrive or another document system.
Edit a Confluence or Jira export
Confluence 'Export to Word' files are web archives with a .doc name and become real Word documents with their pictures. Jira's Word export converts too, but its linked pictures are left out.
Reuse old templates
Letterheads, forms and contract templates saved as .doc become .docx files you can keep editing in current Word.
Open Word 95 files
Documents from Word 95 convert too, so files from the 1990s become editable in current software.
Meet a .docx requirement
Publishers and submission systems that ask for .docx take the converted manuscript or form.
Update an old CV
Bring a CV written years ago in Word 2003 into .docx and keep its layout as you update it.
Process documents with modern tools
Scripts and tools that read .docx, such as document generators and text-extraction libraries, can work with the converted files.
Send files for translation
Translation tools work with .docx files, so convert legacy .doc files before sending them to a translator.
SUPPORTED FILES
Word 97-2003 and Word 95 documents, plus web exports named .doc, are supported.
The standard binary Word format.
Older documents convert too.
Web pages and MHT archives named .doc become real Word documents.
Opened the way Word opens it.
Upload many DOC files and download the DOCX files as a ZIP.
TROUBLESHOOTING
Most differences come from fonts and features the target format handles differently.
01
The document is laid out by LibreOffice, and fonts the server doesn't have are replaced with similar ones. Embed fonts in the original to avoid this.
02
Open the file, save a copy without a password and upload that copy.
03
A cut-off or broken upload can't be read. Download or copy the original again.
04
Rarely used Word features can be simplified during conversion.
05
Pictures only linked from a server aren't fetched. Embed them before exporting.
06
Web-page exports over 10 MB and web archives over 50 MB are refused.
Word, Excel and LibreOffice can save DOC as DOCX once installed. dragdropdo does the same conversion in the browser, on any device.
