Your files stay on your Mac.
Convertessa reads .man roff source files and writes them out as OpenDocument Text (.odt) documents. Headings, body text, and structured sections from the roff markup land in a fully editable ODT file ready for any word processor. Conversion runs entirely offline — your files never leave the Mac.
Drag one .man file or an entire folder of man pages onto Convertessa. Batch mode processes all files in a single pass without any size limit.
Choose OpenDocument Text from the output format list. Set quality to control output fidelity before you convert.
Click Convert. Convertessa writes the .odt files beside your originals and strips all embedded metadata. Nothing is uploaded anywhere.
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.
No. Convertessa runs entirely offline. Your .man files are never uploaded to any server — all conversion happens locally on your Mac.
Yes. Drop a folder onto Convertessa or run convertessa *.man --to odt in the terminal to batch-convert every .man file in the directory in one pass.
Convertessa strips embedded metadata from the output. The text content and structure of the man page are preserved in the ODT, but document-level metadata is removed.
