Your files stay on your Mac.
Convertessa reads your Djot markup files and renders them as OpenDocument Text documents (.odt) that any word processor can open. Headings, lists, emphasis, links, block quotes, and fenced code blocks are all mapped to their ODT equivalents. Everything runs locally — your files never leave the Mac.
Drag one .djot file or an entire folder onto Convertessa. Batch mode processes every file in the folder in a single pass without extra configuration.
Choose OpenDocument Text from the output list. If the output document contains embedded images, set quality to control how they are compressed in the .odt file.
Click Convert. Convertessa writes .odt files alongside the originals. No upload, no account, no internet connection required.
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 entirely on your Mac. Your .djot files are never sent to any server.
Headings, paragraphs, bold, italic, strikethrough, links, ordered and unordered lists, block quotes, and fenced code blocks are all mapped to their OpenDocument Text equivalents. Metadata and EXIF data embedded in any images are stripped during conversion.
Yes. Drop a folder onto Convertessa or run convertessa ./folder/ --to odt from the command line. Every .djot file in the folder is converted in one pass.
