Free Online Markdown Formatter
Format and beautify Markdown with conservative source cleanup for spacing, headings, and list markers. Review every change before applying it.
Original Markdown
Formatted result / diff
##A heading * first item * second item ```ts const untouched = true; ``` | Name | State | | --- | --- | | Formatter | Ready |
The original text has not been changed.
Formatting Rules and Limitations
Fenced code and Markdown hard line breaks are never rewritten. Raw HTML, footnotes, and block math are preserved with a warning. The formatter does not delete or reorder content when it cannot be confident.
How to Format Markdown
Paste Markdown, format it, compare the original and result, then apply, copy, or download the reviewed output.
What This Formatter Changes
Fix reliable heading spacing, list markers, and stable whitespace while preserving fenced code and hard line breaks.
What It Deliberately Does Not Rewrite
This is not a Prettier replacement. It does not restructure documents, normalize emphasis styles, reflow paragraphs, or align Markdown tables. Raw HTML, footnotes, and block math cause the original document to be preserved with a warning.
Format README, Obsidian and Documentation Markdown
Tidy basic formatting in README files, Obsidian notes, technical documentation, and blog drafts without handing control to a server-side formatter or changing the document's intended structure.
Review Changes Before Applying
The original stays on the left while the formatted result appears on the right. Compare the two versions, then apply, copy, or download the result only when the conservative changes match your intent.
