Your files stay on your Mac.
Convertessa reads each AsciiDoc document and maps its heading hierarchy — from top-level sections down to sub-subsections — into a nested OPML outline. Every heading level becomes a corresponding outline node, so the document structure is faithfully reproduced. Conversion runs entirely on your Mac; nothing is uploaded.
Drag a single .adoc file or an entire folder onto Convertessa. Batch mode picks up every AsciiDoc document in the folder automatically.
Choose OPML from the output format list. Convertessa will map each heading level in your AsciiDoc source to the matching depth in the OPML outline tree.
Click Convert. Convertessa writes one .opml file per source document, preserving the full heading hierarchy. 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.
All of them. Convertessa maps every heading level (= through =====) to the corresponding OPML outline depth, so the full document hierarchy appears in the output file.
Yes. Point Convertessa at a folder and it converts every .adoc file inside, writing one .opml file per source document. Use the CLI for scripting: convertessa ./docs/ --to opml.
Yes. Document metadata embedded in the AsciiDoc header (author, revision, attributes) is stripped during conversion; only the structural outline is written to the OPML output.
