| Description | MSG file is a MS Outlook email saved to a separate file. Such mail format is also used in The Bat!, Windows Mail, MDaemon, etc. It contains email fields and attachments, supporting both plain text and HTML mail formatting. As a rule, the mail content is encoded by base64 scheme. Encoding is required for mail to pass the mail servers that originally process text only. MSG can be opened in the program version it was created in, and the file will conflict with all other applications. To convert .MSG to PDF, HTML, TXT or other formats use the online converter. |

Outlook MSG files are a proprietary binary format — only Outlook and a handful of specialized tools can open them. Converting an MSG email to DOC produces a readable Word document with the full email content: headers, body, and attachment list. Anyone with Word or a DOC viewer can read it without Outlook installed.
MSG is Microsoft Outlook's native message format. It stores a complete email — headers, body (plain text or HTML), attachments, and metadata — in a single binary file using the Compound Document Binary File Format (CFB). MSG files are created when you drag an email out of Outlook or export it individually. Only Outlook, Exchange tools, and a few third-party viewers support MSG natively.
DOC is Microsoft Word's binary document format from Office 97–2003. It is universally supported across Word versions, LibreOffice, Google Docs, and virtually every word processor. Converting an MSG to DOC makes the email content available in a standard, editable format that any word processor can open, search, and print without special email software.
