Markdown vs Rich Text vs Plain Text: When to Use Each
Choosing between Markdown, rich text, and plain text affects portability, readability, and editing workflow. This comparison helps you select the right text format for documentation, notes, and content creation.
Key Takeaways
- Each text format represents a different philosophy about how formatting should be handled.
- Plain text contains only characters with no formatting information.
- Markdown uses simple punctuation characters to indicate formatting: `#` for headings, `*` for emphasis, `-` for lists.
- Rich text stores formatting instructions alongside content.

The Three Text Paradigms
Each text format represents a different philosophy about how formatting should be handled.
Plain Text
Plain text contains only characters with no formatting information. It's the most portable and long-lived format โ a plain text file from 1970 is still perfectly readable today.
Best for: Configuration files, code, logs, data interchange, email.
Markdown
Markdown uses simple punctuation characters to indicate formatting: # for headings, * for emphasis, - for lists. It's readable as plain text but can be rendered into formatted HTML or PDF.
Best for: Technical documentation, README files, blogs, notes, knowledge bases.
Rich Text
Rich text stores formatting instructions alongside content. Formats like RTF, DOCX, and Google Docs provide WYSIWYG editing with fonts, colors, images, and complex layouts.
Best for: Business documents, letters, resumes, printed materials.
