Your files stay on your Mac.
JATS XML encodes journal articles and scientific content as a hierarchy of tags. Convertessa reads those tags and writes a .docx file with matching headings, paragraphs, and inline text that opens cleanly in Microsoft Word or any compatible editor. Metadata embedded in the JATS source is stripped during export.
Drag one .jats file or an entire folder of articles onto Convertessa. Your files never leave your Mac — conversion runs fully offline.
Pick Word (.docx) from the output list. Set quality to fine-tune the export if needed, then confirm your selection.
Convertessa maps JATS elements to Word styles and writes one .docx per article. Open the result straight in Microsoft Word.
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.

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 common JATS structural elements — article titles, abstracts, section headings, paragraphs, and inline markup — to their Word equivalents. Formatting with no direct Word counterpart is rendered as plain text so nothing is silently dropped.
Yes. Drop an entire directory onto Convertessa or run convertessa ./articles/ --to docx in the terminal. Each .jats file becomes its own .docx output.
Yes. Convertessa strips XML metadata from the .jats source during conversion, so the resulting .docx contains only the document content — not the publishing or authorship metadata embedded in the original file.
