Your files stay on your Mac.
Convertessa reads each .rst file and rewrites it in Djot syntax, mapping headings, bullet lists, numbered lists, code blocks, inline markup, and hyperlinks to their Djot equivalents. Conversion runs entirely on your Mac — no files are uploaded and no internet connection is required. Process a single document or a full Sphinx documentation tree in one pass.
Drag one .rst file or an entire folder into Convertessa. The app queues every file it finds and shows you the full list before anything runs.
Choose Djot from the output format list. Convertessa maps RST headings, directives, inline roles, and block-level elements to their Djot equivalents.
Click Convert. Each source file becomes a .djot file placed alongside the original. Everything runs offline — files never leave your Mac.
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 maps standard RST elements — section headings, bullet and numbered lists, inline code, fenced code blocks, hyperlinks, bold, and italic — to their Djot equivalents. The output preserves the document's content structure.
Yes. Point Convertessa at the folder containing your .rst files and it converts every file in one pass. From the command line: convertessa ./docs --to djot. No file leaves your machine.
