Ms to DOCM Converter
Processing entirely on your device — large files may take a moment.
Convert DOCM exactly like DOCX — text, tables and images extract the same way. If your files are still in Ms format, this page is the shortcut: 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.
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
- ✓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
About the DOCM format
DOCX is the modern Microsoft Word format (Office Open XML, default since Word 2007). A file is actually a ZIP package of XML parts — document body, styles, numbering, headers, embedded media — which is what lets Word, Google Docs, LibreOffice, WPS and Pages all open it natively. Text flows around styles rather than absolute positions, so a document adapts to the page it is rendered on.
It is the format of collaboration: tracked changes, comments, styles and templates are first-class citizens, and office ecosystems assume it. The trade-off is layout drift — the same DOCX paginates slightly differently across renderers, and very complex layouts (exact positioning, text over images) can shift. For contracts in progress it is ideal; for the signed final, export a PDF.
+Strengths
- ✓Fully editable with styles, track changes and comments
- ✓Opens natively in Word, Google Docs, WPS, LibreOffice
- ✓Flowing layout adapts to any page size
!Limitations
- −Pagination and layout shift between renderers
- −Complex layouts may not survive round-trips
- −Not suitable as a final, fixed distribution format

Frequently asked questions
Is this Ms to DOCM 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 DOCM?
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.
Will the layout of my Ms file be preserved exactly?
This converter renders your Ms content into DOCM 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.
Can I edit the DOCM result afterwards?
That depends on the target: DOCM 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.
