DOCX vs MD

DOCX (Word Document) uses MIME type application/vnd.openxmlformats-officedocument.wordprocessingml.document in the Documents & Text family, whereas MD (Markdown) uses text/markdown in the Documents & Text family. Each optimizes for different trade-offs in file size, fidelity, and software compatibility.

DOCX is the default document format for Microsoft Word since 2007, based on the Office Open XML standard. It stores text, formatting, images, tables, and macros in a compressed XML-based package.

Markdown is a lightweight text-based markup language created by John Gruber and Aaron Swartz in 2004. A .md file uses simple conventions (*italic*, **bold**, # headings, - lists) that compile to HTML. It became the default writing format for GitHub READMEs, Stack Overflow posts, Discord messages, and most developer documentation.

DOCX files open in Microsoft Word, Google Docs (free), LibreOffice Writer (free), and Apple Pages. You can also view them in web browsers using OneDrive or Google Drive.

Markdown files are plain text — open in any text editor. For formatted preview use VS Code (built-in preview), Typora, Obsidian, or upload to GitHub/GitLab which render Markdown automatically. Every note-taking app (Notion, Bear, Joplin) handles Markdown natively.

Use DOCX when the document will be edited by others or needs collaborative review. Use PDF when you want to lock the layout and ensure the document looks identical on every device and printer.
