Your files stay on your Mac.
Textile is a lightweight markup language used in older content pipelines and Ruby-based applications. Djot is a modern successor with unambiguous, well-specified syntax designed for long-term readability. Convertessa rewrites each Textile file into valid Djot markup, preserving headings, lists, links, and inline formatting.
Drag one or more .textile files onto Convertessa, or point it at a folder to queue every file inside for conversion.
Pick Djot from the output format list. Convertessa writes one .djot file for every source file you dropped.
Click Convert. All processing runs locally on your Mac — your files never leave your machine.
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 standard Textile headings, paragraphs, bold, italic, code spans, block code, ordered and unordered lists, and hyperlinks to their Djot equivalents. Textile-specific constructs with no Djot counterpart are rendered as plain text so the output stays well-formed.
Yes. Drop a folder onto Convertessa or pass a directory to the CLI: convertessa ./folder/ --to djot. Every .textile file inside is converted and placed in the output directory.
No. Convertessa runs entirely on your Mac. No files are uploaded and no network calls are made — conversion works fully offline.
