Your files stay on your Mac.
reStructuredText is a plain-text markup language used for Python documentation, technical manuals, and Sphinx-based sites. Convertessa reads your .rst files on-device and writes them out in whichever document or markup format you choose — nothing is uploaded. Convert one file or an entire folder without touching the internet.
Drag a single .rst file into Convertessa, or point the CLI at a directory to queue every .rst document inside it for conversion.
Pick a target — Markdown, DOCX, HTML, EPUB, ODT, LaTeX, or any of the other 22 supported outputs — from the output format list.
Convertessa converts locally and writes the result to the same folder. Your .rst files are never uploaded anywhere.
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.
