Your files stay on your Mac.
Djot uses a strict, unambiguous markup spec; Emacs Muse uses its own lightweight text conventions for Emacs-based publishing. Convertessa rewrites Djot headings, ordered and unordered lists, inline emphasis, code spans, and hyperlinks into their Muse equivalents. The resulting .muse file opens directly in an Emacs Muse or Planner workflow without manual cleanup.
Drag one .djot file or an entire folder onto Convertessa. Every file stays on your Mac — conversion runs fully offline with no upload.
Pick Emacs Muse from the output format list. Convertessa maps each Djot construct — headings, emphasis, links, fenced code blocks — to the equivalent Muse syntax.
Click Convert. Convertessa writes .muse files alongside the originals and preserves your folder structure for batch jobs. Embedded metadata is stripped from the output files.
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 converts ATX headings, paragraphs, ordered and unordered lists, bold and italic emphasis, inline code, fenced code blocks, and hyperlinks. Block-level Djot constructs that have no direct Muse counterpart are preserved as literal text.
Yes. Drag a folder onto Convertessa or run convertessa ./notes --to muse from the terminal. Every .djot file in the folder is converted; other file types are skipped. Nested folders are processed recursively.
Yes. Any embedded metadata in the Djot source is stripped during conversion. The output .muse files contain only the document content.
