Your files stay on your Mac.
Convertessa reads your .adoc source files and writes standards-compliant DocBook XML — the format expected by publishing toolchains, DITA pipelines, and technical documentation systems. The conversion runs entirely on your Mac; your files never leave the machine. Drop a single file or an entire folder and get DocBook output in seconds.
Drag one or more .adoc files — or a whole project folder — into Convertessa.
Choose DocBook from the output format list. Convertessa targets the DocBook XML schema and writes one .dbk file per source document.
Click Convert. Convertessa writes the DocBook files to the folder you choose. Everything runs offline — nothing is uploaded.
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.
