Your files stay on your Mac.
Convertessa reads the section headings in your Typst source file and writes them out as a nested OPML outline. The resulting file captures the document hierarchy — parts, sections, and subsections — in a format compatible with outlining tools, podcast clients, and RSS readers. Nothing is uploaded; all processing runs on your Mac.
Drag one .typ file or an entire folder of Typst documents onto Convertessa. Batch mode processes every file in the folder in one pass.
Choose OPML from the output format list. Convertessa maps each heading level in your Typst source to a matching OPML outline element, preserving the full depth of the hierarchy.
Click Convert. Each .typ file produces a companion .opml file in the same folder. Open it in any OPML-compatible app or import it straight into your outliner.
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.

Yes — drop the folder onto Convertessa or use the CLI batch form: convertessa /path/to/folder --to opml. Each .typ file produces its own .opml output file.
