Markdown Formatter

What is Markdown Formatter?

A Markdown formatter normalizes Markdown documents by ensuring consistent heading spacing (exactly one space after hash marks), uniform list markers (standardized to dashes), cleaned-up blank lines (no more than one consecutive blank line), and trimmed leading/trailing whitespace. Consistent Markdown formatting improves readability, reduces diff noise in version control, and ensures predictable rendering across different Markdown processors (GitHub, GitLab, Notion, Hugo, Jekyll). The formatter respects Markdown semantics — it does not change the meaning or rendering of your document, only the whitespace and formatting conventions.
