Your files stay on your Mac.
Texinfo is the GNU project's native documentation format, producing .info pages readable by Emacs and the info command. Convertessa reads your .rst source files and outputs .texi files structured around Texinfo's @node and @menu system. Headings, cross-references, and code blocks are mapped to their Texinfo equivalents.
Drag one .rst file or an entire folder of documentation into Convertessa. All processing happens locally on your Mac — nothing is uploaded.
Pick Texinfo from the output format list. Convertessa will produce a .texi file for each source document you dropped in.
Click Convert. Your .texi files appear in the output folder, ready to process with makeinfo or drop into a GNU documentation build.
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.
No. Convertessa runs entirely on your Mac. Your .rst files are read and converted locally — nothing ever leaves your machine.
Yes. Drop a folder onto Convertessa or pass a directory to the CLI (convertessa ./docs/ --to texi) and every .rst file in the folder is converted in one pass.
The converter maps RST headings to Texinfo @chapter and @section commands, produces @node entries with a @menu, and renders code blocks as @example or @verbatim environments.
