Your files stay on your Mac.
Convertessa reads each outline node in your OPML file — text, nesting, and attributes — and writes equivalent reStructuredText. Hierarchy becomes RST sections and bullet lists. Every step runs on your Mac; no file ever leaves the machine.
Drag one OPML file or an entire folder onto Convertessa. The app parses each outline node, its text content, and nested children ready for conversion.
Choose reStructuredText from the output format list. Convertessa maps OPML nesting to RST section headings and indented bullet lists.
Click Convert. Each .opml file produces a corresponding .rst file in the same folder, ready for Sphinx, Docutils, or any RST toolchain.
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.
Each level of nesting becomes an indented bullet list in the RST output. Top-level outline nodes map to section headings, and their children appear as list items beneath them — preserving the full outline depth.
Yes. Feed-specific attributes such as xmlUrl and htmlUrl are included as inline annotations in the RST output so no data is silently dropped.
Yes. Drop a folder onto Convertessa or run convertessa folder/ --to rst in the terminal. Every OPML file in the folder is converted in one pass, each producing its own .rst file.
