About the Markdown Formatter
The Markdown Formatter beautifies Markdown documents using Prettier — normalizing headings, lists, tables, and line spacing for consistency and tidiness.
How it works: Prettier parses the Markdown and rewrites it in a standard style (e.g. a space after #, table formatting, and consistent list indentation).
Markdown is used for READMEs, documentation, and notes. Consistent formatting keeps documents tidy and produces clean diffs in version control.
FAQ
Can this Markdown tool both format and minify?
This tool focuses on prettifying (format/beautify) Markdown for readability.
Is my code sent to a server?
No. Markdown is processed entirely in your browser using JavaScript/WebAssembly. Your code never leaves your device.
