Your files stay on your Mac.
Djot is a lightweight markup language designed as a stricter, unambiguous alternative to Markdown. Converting a .djot file to Markdown rewrites every markup construct — headings, emphasis, links, code spans, and block elements — into standard .md syntax that editors, static-site generators, and documentation pipelines already understand. The result is a plain Markdown file with no proprietary tooling required.
Drag one .djot file or an entire folder into Convertessa. Your files stay on your Mac — nothing is uploaded.
Choose Markdown from the output list to set .md as the target format.
Click Convert. Convertessa rewrites the Djot markup into Markdown syntax and saves each .md file alongside the original.
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.
Convertessa maps Djot headings, paragraphs, ordered and unordered lists, blockquotes, fenced code blocks, and inline elements — bold, italic, inline code, links, and images — to their Markdown equivalents.
Yes. Drag the folder into Convertessa, or run convertessa /path/to/folder --to md in the terminal. Every .djot file in the folder is converted in one pass.
No. Convertessa writes new .md files and leaves the source .djot files untouched.
