Ms to HTM Converter
Processing entirely on your device — large files may take a moment.
roff ms Macros and HTML Document (HTM) exist for different jobs: The ms macros are the other roff formatting package (alongside man) — Bell Labs' classic typesetting layer used for troff papers and Unix documentation since the 1970s. Convert HTM files exactly like HTML: to PDF for printing, to Markdown for editing, or into other documents.
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 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

- ✓Tiny macro set, no GUI needed
- ✓groff ships everywhere
!Limitations
- −Niche outside academic/Unix circles
- −No rich media

About the HTM format
HTML is the markup language of the web itself. A document is plain text decorated with tags that describe structure — headings, paragraphs, lists, links, tables, images — and browsers turn that structure into a rendered, styled page. It is both a format and a program target: CSS styles it and JavaScript makes it interactive.
As a document format, HTML's strength is universality: any device with a browser displays it, text stays selectable and searchable, and links make it navigable. Its weakness is that rendering depends on the surrounding CSS and viewport, so it is a flowing document, not a fixed-layout one — printing or archiving an HTML page is inherently an approximation.
+Strengths
- ✓Displays on every device with a browser
- ✓Semantic structure: headings, links, tables, media
- ✓Text remains selectable, searchable and accessible
!Limitations
- −Final look depends on CSS and viewport
- −Not a fixed-layout or print format
- −Untrusted HTML must be sanitized before display

Frequently asked questions
Is this Ms to HTM 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 Ms to HTM?
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.
Does the conversion work offline?
Yes. Once the page has loaded, the conversion itself runs entirely inside your browser — you can even disconnect and keep converting. No file ever touches a server.
Can I edit the HTM result afterwards?
That depends on the target: HTM 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.
