Prettier is the most popular opinionated code formatter, supporting many languages including Markdown. It enforces consistent formatting by parsing your code and reprinting it with its own rules, ensuring uniform style.

What does the prose wrap option do?

Prose wrap controls how paragraphs are wrapped. 'Always' wraps at the print width, 'Never' removes existing wrapping to single lines, and 'Preserve' keeps the original wrapping as-is.

Does formatting change the meaning of my markdown?

No, Prettier only changes formatting (whitespace, indentation, line wrapping) without altering the semantic meaning of your markdown. The rendered output will look the same.

Can I use this with my Prettier config?

The tool provides common Prettier options (print width, tab width, prose wrap, etc.) that you can configure to match your project's Prettier configuration. The output will match what Prettier CLI would produce with the same settings.

Is my content private during formatting?

Yes, Prettier runs entirely in your browser via WebAssembly. No content is sent to any server, ensuring complete privacy for your documents.
