MD to Ms Converter
Processing entirely on your device — large files may take a moment.
Markdown Document and roff ms Macros exist for different jobs: Markdown is the lightweight markup language used by GitHub, Notion and countless blogs: a few symbols turn plain text into headings, lists, links and code blocks. Produce ms source when a document must run through classic troff/groff typesetting.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.

About the MD format
Markdown (John Gruber, 2004) is plain text that renders into rich documents: `#` headings, `*` emphasis, lists, links, code fences. You can write it in any editor, read it as-is, diff it in git, and twenty years later it still opens — which is why GitHub, Stack Overflow, Notion, Obsidian and every static-site generator settled on it for prose.
Its one honest weakness is dialect fragmentation: tables, footnotes and task lists all started as extensions (GFM, MultiMarkdown, Pandoc), so a sophisticated document can render differently across tools. Core Markdown — headings, lists, links, code — is bulletproof everywhere.
+ Strengths
- ✓Future-proof plain text, renders anywhere
- ✓Perfect for version control and documentation
- ✓Low-friction: readable even unrendered
! Limitations
- −Extension dialects fragment advanced features
- −Complex layout and precise design are out of scope
About the Ms format
The ms macros are the other great roff package: Bell Labs' general-purpose typesetting layer that produced papers, memos and books on Unix since the 1970s. Where man pages have one narrow shape, ms gives you .TL titles, .NH numbered headings, .DS display blocks — a full letterpress-grade document system in a few dozen macros.
ms remains the shortest path from plain text to a classically typeset PDF via groff. Generating ms from Markdown sources with Pandoc lets modern writing flow into that pipeline: the content is authored today, the typography comes from fifty years of Unix tradition.
+ Strengths
- ✓Classic, reproducible print typography
- ✓Tiny macro set, no GUI needed
- ✓groff ships everywhere
! Limitations
- −Niche outside academic/Unix circles
- −No rich media
- −Learning curve comparable to LaTeX

Frequently asked questions
Is this MD to Ms converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for MD to Ms?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Can I edit the Ms result afterwards?
That depends on the target: Ms is designed for what it does, and this converter reproduces its content faithfully rather than inventing editable structure. For heavy re-editing, work from a format built for editing and export the final version here.
Will the layout of my MD file be preserved exactly?
This converter renders your MD content into Ms with pages, proportions and images kept as close to the original as the target format allows. Use the preview before downloading to confirm it looks the way you expect.
