Paste messy Markdown, get clean and consistent output. Normalizes whitespace, list markers, emphasis, and headings. Works entirely in your browser.
A Markdown formatter beautifies inconsistent Markdown — standardizing list markers, emphasis style, heading format, and whitespace — so your documents read cleanly and diff predictably in version control. It's the Markdown equivalent of running a code formatter.
Paste your Markdown and the tool normalizes mixed list markers (-, *, +), collapses extra blank lines, unifies emphasis style (asterisks versus underscores), and trims trailing whitespace, using the same remark engine that powers Prettier's Markdown formatter. GitHub Flavored Markdown — tables, task lists, strikethrough, autolinks — is preserved. Formatting runs locally in your browser with nothing uploaded.
