Processing entirely on your device — large files may take a moment.
roff ms Macros and PDF Document 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 to PDF when you need a fixed, print-ready layout that looks identical everywhere and cannot be accidentally reflowed or edited.
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.

- ✓Tiny macro set, no GUI needed
- ✓groff ships everywhere
! Limitations

About the PDF format
PDF (Adobe, 1993; ISO 32000 since 2008) exists for one promise: the document looks identical everywhere, forever. Fonts get embedded, layout is fixed to the point, and a contract printed from a 2003 file renders the same as one created this morning. That fixed-layout guarantee made it the standard for invoices, manuals, forms, e-books and anything with legal or financial weight.
The same design is what makes PDFs stubborn. They are meant to be presented, not edited — text lives in positioning operators rather than paragraphs, so extraction and re-flow are approximations. Scanned PDFs are worse: pure images with no text layer at all until OCR enters the picture. Still, no other format comes close for final-form document delivery.
+ Strengths
- ✓Pixel-identical rendering on every device and printer
- ✓Fonts, images and color profiles travel inside the file
- ✓Mature ecosystem: forms, signatures, annotations, encryption
! Limitations
- −Hard to edit by design — even small changes need tooling
- −Text extraction is an approximation, not a conversion
- −Scanned PDFs are images without OCR
