Convert R Markdown to Markdown.
Drop an .rmd file and get its Markdown body back, with the knitr chunk headers tidied up. It runs entirely in your browser, so your file never leaves your device.
Drag & drop your files
or
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.
Already Markdown,
minus the knitr.
An R Markdown file is Markdown wrapped around a YAML header and R code chunks. This hands you the body back essentially verbatim and only trims the chunk fences to a plain language tag.

Everything you
actually need.
Your R Markdown body in, clean Markdown out, with no server and no account anywhere.
It never leaves your browser
Your .rmd file is read and converted on your own device. Nothing is uploaded to any server, ever.
# Heading
- point one
3 chunks
AI & RAG ready
Optional cleanup, YAML front matter, a table of contents and RAG chunk export.
Works offline
Once the page has loaded you can switch off your connection and it keeps converting.
Chunks simplified
Code-chunk headers like {r, echo=FALSE} are trimmed to a plain r language tag, so the code reads as a normal fenced block.
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.
Barely a
scratch.
Because the body is already Markdown, almost nothing has to change. These are the same notes the Formats list shows for R Markdown, so the page never drifts from what the converter really does.
