Your files stay on your Mac.
Convertessa reads your .adoc files and rewrites them in Djot — a lightweight markup language designed for unambiguous, consistent parsing. Headings, paragraphs, lists, code blocks, links, and inline emphasis all carry across. Document metadata is stripped; content structure is preserved.
Drag one .adoc file or an entire folder onto Convertessa. Nothing is uploaded — conversion runs locally on your Mac.
Choose Djot from the output format list. Convertessa maps AsciiDoc elements — headings, lists, code blocks, links, and emphasis — to their Djot equivalents.
Click Convert. Your .djot files appear alongside the originals, ready for any text editor or Djot-aware build pipeline.
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.
Read the full CLI documentation →Shrink Convertessa down to a small, focused window — drop, convert, done, with your recent conversions one click away.

New formats, new features, and fixes — every release, on the record.
Djot covers the common structural elements — headings, paragraphs, lists, code blocks, links, and inline emphasis. AsciiDoc-specific features such as admonitions and complex macros have no direct Djot equivalent and are omitted in the output.
No. Convertessa converts entirely on your Mac. Your .adoc files never leave the machine.
Yes. Drop a folder onto Convertessa or run convertessa ./docs/ --to djot in the terminal. Every .adoc file inside is converted in one pass.
