Your files stay on your Mac.
reStructuredText files encode headings, bullet lists, bold text, and code blocks as plain-text directives. Convertessa reads each .rst file and produces a Word document that preserves that structure—ready to hand off to editors who work in Microsoft Word. Everything runs locally; no file ever leaves your Mac.
Drag one .rst file or an entire folder onto Convertessa. Batch mode picks up every .rst file in the folder and queues them in one pass.
Choose Word (.docx) from the output format list. Convertessa targets the .docx specification so the result opens in Microsoft Word, Google Docs, and LibreOffice without compatibility warnings.
Click Convert. Convertessa processes each file on your Mac with no upload and no internet connection required. Word documents appear alongside the originals as soon as conversion finishes.
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.
Yes. Convertessa maps RST section titles to the corresponding Word heading styles—Heading 1, Heading 2, and so on—so the document outline is intact when you open it in Word.
Yes. Drop the folder onto Convertessa or run convertessa *.rst --to docx from the folder in your terminal. Every .rst file is converted in a single batch and the resulting .docx files are written next to the originals.
No. Convertessa runs entirely on your Mac. Your files are never uploaded, transmitted, or stored anywhere outside your machine.
