Your files stay on your Mac.
Man Pages are authored in roff, a decades-old typesetting language that most modern editors cannot open directly. Convertessa reads the roff source and produces a .typ file you can open, edit, and re-typeset with the Typst compiler. Section structure, heading levels, and inline formatting are preserved — and everything runs offline, so files never leave your Mac.
Drag one .man file or an entire folder of roff sources onto Convertessa. Batch mode processes every file in one pass.
Choose Typst from the output format list. Convertessa will produce a .typ file for each Man Page you dropped.
Click Convert. Convertessa processes everything locally — your roff sources never leave the Mac — and saves the Typst files alongside the originals.
Images, audio, video, documents, archives and eBooks — all converted natively, right on your Mac.
Pick a format you have — see everything Convertessa can turn it into.
Convert hundreds of files at once with per-type group defaults and individual overrides.
First-class support for HEIC, AVIF and WebP — encode and decode, both ways. Read JPEG XL and a dozen more modern formats too.
Drop files anywhere on the window. Native, instant, and exactly what you’d expect on a Mac.
Dial in compression, resolution and bitrate. Keep originals pristine or shrink for sharing.
Never overwrite a file by accident. Convertessa appends safe suffixes automatically.
Every job is logged locally. Re-run a previous conversion or revisit recent outputs in a click.
Bundle your converted files straight into a single ZIP, TAR or 7z — packaged and ready to share the moment a job finishes.
Right-click any file in Finder and choose Convert. A Quick Action handles it on the spot — no need to open the app first.
Shrink Convertessa to a tidy mini window that tucks into a corner — just a drop zone and a format picker for quick, one-off conversions.
No cloud. No account. No upload. Every conversion happens entirely on-device, using the power already in your Mac. What you convert is nobody’s business but yours.
Script conversions, wire them into your build, or batch a folder from the terminal. The same engine, no GUI required.

New formats, new features, and fixes — every release, on the record.
Yes. Convertessa maps roff section macros such as .SH and .SS to Typst headings, and inline macros for bold and italic are carried over as Typst markup.
Yes. Pass a folder path on the command line (convertessa ./man-pages/ --to typ) or drop a folder onto the app window, and Convertessa converts every .man file in a single pass.
Yes. Convertessa strips embedded document metadata from the Typst output, so author fields and other header data from the roff source are not carried into the converted file unless they appear as visible body text.
