Your files stay on your Mac.
reStructuredText files become JATS XML — the Journal Article Tag Suite standard used by academic publishers, repositories, and archiving systems such as PubMed Central. Convertessa parses your .rst markup and outputs valid JATS article tags, preserving section hierarchy and content structure. Every conversion runs locally on your Mac; your files never leave your machine.
Drag one .rst file or an entire folder of documents into Convertessa. Batch conversion processes all files in a single pass with no size limit.
Pick JATS XML from the output format list. Convertessa targets the JATS article schema, producing XML that downstream publishing pipelines and repositories expect.
Click Convert. Convertessa writes .xml files alongside your originals — or to a destination folder you specify. 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.

JATS (Journal Article Tag Suite) is the XML standard for scholarly and scientific articles. Academic publishers, repositories such as PubMed Central, and archiving systems accept JATS XML as their primary exchange format for structured article content.
Yes. Convertessa removes embedded document metadata during conversion, so the output JATS XML contains only structured content — no author environment details or tool fingerprints carried over from the source file.
Yes. Drag a folder into Convertessa or run convertessa ./docs/ --to jats from the command line. Every .rst file in the folder is converted in one pass.
