DOC converter
Convert your DOC files to any format.
What is a DOC file?
DOC is the legacy Word format — a binary file superseded by DOCX in 2007, still floating around from old templates and archives.
First released in 1983 by Microsoft, it uses lossless compression and no transparency, which makes it best suited to old Word documents from Office 97-2003 that newer apps struggle to open.

Advantages of the DOC format
Opens in very old software
DOC is understood by Word versions going back to the 1990s, making it the safest bet when a document must open on genuinely ancient software.
Widely recognized
Even though DOCX has been the default since 2007, most word processors and viewers still open .doc files without issue.
Simple binary structure
Its compound-file format is well understood by conversion tools, so text, images and tables extract reliably.

DOC: frequently asked questions
What's the difference between DOC and DOCX?
DOC is the older binary format used by Word 97-2003; DOCX, introduced in 2007, is a modern ZIP-based XML format that's smaller and more robust. Converting DOC to DOCX brings an old file up to the current standard.
Why won't my .doc file open in some apps?
Some newer or web-based word processors have dropped support for the legacy binary format. Converting to DOCX guarantees compatibility everywhere.
Will formatting be preserved when converting DOC?
Text, headings, tables, images and basic layout carry over well. Very old macros or legacy Word features specific to the binary format may not survive.
Is DOC still used today?
Rarely for new documents, but it still appears in old templates, archives and legal or government files created before 2007.
