Your files stay on your Mac.
Djot is a lightweight, unambiguous markup format. AsciiDoc is a rich publishing format used in technical documentation, books, and manuals. Convertessa translates your Djot source into valid AsciiDoc so you can drop it straight into Asciidoctor or any AsciiDoc toolchain.
Drag individual .djot files or an entire folder into Convertessa. Batch mode processes every file at once — no size limit, no upload.
Choose AsciiDoc from the output format list. Convertessa maps Djot headings, lists, code blocks, links, and inline formatting to their AsciiDoc equivalents.
Click Convert. Your .adoc files appear in the same folder, ready for Asciidoctor, Antora, or any AsciiDoc pipeline — without a network connection.
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.
