Your files stay on your Mac.
Convertessa reads the roff formatting directives in your Man Page file and renders them as Rich Text (.rtf). Section headings, bold type, and inline code are carried over as RTF styling any word processor can open. Conversion runs entirely on your Mac — no file is ever uploaded.
Drag one .man file or an entire folder of man pages onto Convertessa. Batch mode processes every file in the folder in one pass.
Choose Rich Text from the output list. Set quality to control RTF fidelity, then confirm your selection.
Click Convert. Convertessa renders each roff source to .rtf, strips document metadata, and saves the output alongside your 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.
Convertessa handles the standard man-page macro sets — man and mdoc — covering section headings, bold, italic, and inline code as used in typical Unix man pages.
Yes. Pass a folder path with the CLI (convertessa ./man-pages/ --to rtf) or drag the folder onto the app. Every .man file inside is converted in one batch.
Yes. Convertessa removes document metadata from the .rtf output, so author fields and tool fingerprints embedded in the roff source do not carry over.
