Your files stay on your Mac.
JATS XML wraps journal article content in structured tags for publishers and archival databases. Converting to plain text removes every tag, attribute, and namespace declaration, leaving the article's readable prose as a clean .txt file. The conversion runs locally on your Mac — no file is uploaded anywhere.
Drag one .jats file or an entire folder of articles onto Convertessa. Batch mode processes every JATS file in the folder in one pass.
Select Plain Text from the output format list. Convertessa will strip all XML markup from each source file and write a corresponding .txt.
Click Convert. Each .jats becomes a .txt containing the article's plain prose — body text, abstracts, and section headings — with all XML tags removed.
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 extracts the text nodes from the JATS document — body paragraphs, abstracts, titles, and keyword lists — and writes them as plain lines. Structural tags, inline markup such as <bold> or <xref>, and XML attributes are removed.
Yes. XML attributes and metadata elements embedded in the JATS markup are stripped during conversion. The output contains only the readable text content of the article.
Yes. Drag the folder onto Convertessa or use the CLI: convertessa ./articles/ --to txt. Every .jats file in the folder is converted and a matching .txt is written alongside it.
