Convert Markdown to Markdown.
Drop a .md, .markdown or .mdx file and get clean, consistent Markdown back. It runs entirely in your browser, so your file never leaves your device.
Drag & drop your files

Optimize for AI & RAG
Extra cleanup for LLM ingestion: strip HTML, fix smart quotes, tidy Unicode and spacing.
Add YAML front matter
Prepend a metadata block (title, source, date, word & token counts) for knowledge bases and RAG.
Add table of contents
Build a linked index from the headings. Handy for long documents.
Export RAG chunks (.json)
Split the result into retrieval-ready chunks. Download per file from the result panel.
Most converters quietly upload your documents to a server. This one physically can't.
Same words,
one tidy style.
Markdown from many sources mixes asterisk and dash bullets, stray spacing and odd blank lines. Your content stays exactly the same; only the style is normalised into one clean, consistent look.

Lossless by default
Your content passes through unchanged, including MDX JSX. Only the spacing and bullet style are tidied.
Unicode safe
Accents, symbols and non-Latin scripts come through intact as UTF-8.
Free, and unlimited
No sign-up, no quotas, no watermarks. Convert one file or a thousand; it all runs the same way, on your own device.
What survives
the trip.
Converting Markdown is lossless: your content passes through unchanged and only the spacing and bullet style get tidied. The right column lists things that simply never exist in a .md file, so nothing is lost. These are the same notes the Formats list shows for Markdown.
