Your files stay on your Mac.
Convertessa reads your .man roff source and rewrites each document section as a Jupyter Notebook cell, producing a .ipynb file ready to open in JupyterLab or VS Code. Conversion runs entirely on your Mac — files never leave the machine. Batch mode processes a whole folder of man pages in one pass.
Drag one .man file or an entire folder into Convertessa. The app reads roff markup directly — no pre-processing or extraction step needed.
Choose Jupyter Notebook from the output list. Set quality if you want to tune the output, then confirm your destination folder.
Click Convert. Convertessa writes one .ipynb per source file with embedded metadata stripped, leaving clean notebook cells ready to edit or share.
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 parses the roff source and maps each logical section — NAME, SYNOPSIS, DESCRIPTION, and so on — to a separate Markdown cell in the resulting .ipynb file. Inline formatting directives are translated to Markdown equivalents where possible.
Yes. Embedded metadata in the source man page is stripped during conversion, so the resulting .ipynb contains only the document content and structure.
Yes. Pass a folder on the command line — convertessa ./man-pages/ --to ipynb — and Convertessa converts every .man file in that directory, writing one .ipynb per source file.
