Your files stay on your Mac.
Convertessa reads each .docx file and writes a .adoc file that represents the same headings, paragraphs, lists, and tables as AsciiDoc markup. The binary Word format is replaced by readable plain text that version-control tools can diff line by line. The conversion runs entirely on your Mac — nothing is uploaded to any server.
Drag one .docx file or an entire folder onto Convertessa. The source list fills automatically with every document you dropped.
Pick AsciiDoc from the output format list. Convertessa will write one .adoc file for every .docx in your source list.
Click Convert. Each Word document is translated to AsciiDoc markup and saved alongside the originals. Files never leave your Mac.
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.
