Your files stay on your Mac.
Convertessa reads your .rst source files and produces valid DocBook XML — the semantic document format accepted by publishing toolchains, enterprise CMS platforms, and professional documentation pipelines. Every heading, paragraph, list, admonition, and code block is mapped to its DocBook element counterpart. Files never leave your Mac.
Drag one .rst file or an entire folder of documents onto Convertessa. No upload, no account — everything runs locally on your Mac.
Choose DocBook from the output format list. Convertessa maps every RST directive, section title, and inline markup to the corresponding DocBook XML element.
Hit Convert. Convertessa writes one .dbk file per source document, preserving the full structure of your content. Open the results folder when done.
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.
