Your files stay on your Mac.
Converting Djot to DocBook transforms lightweight Djot markup into structured DocBook XML, giving you semantic document elements — sections, paragraphs, emphasis, code listings — that technical publishing toolchains expect. Convertessa runs entirely on your Mac: no file is uploaded, no account is required, and the conversion works without an internet connection. Drop a single file or an entire folder and get DocBook XML in seconds.
Drag one .djot file or a whole folder of them onto Convertessa. Batch mode processes every file in the folder in a single pass.
Choose DocBook from the output format list. Convertessa converts to the format you select — it never guesses or pre-selects a target on your behalf.
Click Convert. Convertessa writes DocBook XML files alongside your originals (or to a folder you specify). Your source Djot files are left untouched.
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.
No. Convertessa runs fully offline on your Mac. Your .djot files are read and written locally — nothing is sent to a server or cloud service at any point.
Yes. Drop a folder onto Convertessa or use the CLI (convertessa ./folder/ --to dbk) to batch-convert every .djot file inside it. Each file is written as a separate .dbk output.
Convertessa strips document metadata from the output when converting document formats. The resulting DocBook XML contains your content structure, not embedded author or toolchain metadata from the source file.
