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, eBooks and fonts — 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.
