What is a DOC file?

Microsoft Word 97-2003 (.doc)

DOC is the legacy Microsoft Word binary document format, used as the default format in Microsoft Office from 1997 through 2003. It stores text, formatting, images, tables, headers, footers, and embedded OLE objects in a proprietary binary format. While DOC files are widely recognized, they have limitations compared to the modern DOCX format: larger file sizes, less reliable cross-platform rendering, and limited support for modern features like content controls and advanced typography. Many organizations still encounter DOC files in legacy archives and older workflows. Converting DOC to DOCX or PDF ensures better compatibility with modern applications while preserving the original content and formatting.
