Your files stay on your Mac.
Converting Rich Text to JATS XML maps your RTF document structure—headings, paragraphs, lists, and inline formatting—into the Journal Article Tag Suite schema. The result is a standards-compliant XML file ready for submission to academic publishers or ingestion into editorial workflows. Convertessa does this entirely on your Mac: no file is uploaded, no internet connection required.
Drag one RTF file or an entire folder onto Convertessa. Every file is queued and processed locally—nothing leaves your Mac.
Choose JATS XML from the output format list. Convertessa maps RTF structure to the JATS Tag Suite schema and strips embedded document metadata before writing the output.
Click Convert. Each Rich Text file becomes a JATS XML document with your headings, paragraphs, and inline formatting preserved, saved alongside the originals or to a destination folder you select.
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.
