Your files stay on your Mac.
AsciiDoc is a plain-text markup language designed for technical documentation, books, and manuals. Convertessa reads your .adoc files locally and converts them into DOCX, HTML, EPUB, Markdown, ODT, and 17 other formats. Nothing is uploaded — every conversion runs on your Mac.
Drop a .adoc file onto Convertessa or select it from the file browser. You can also select an entire folder to convert multiple files at once.
Choose DOCX, HTML, EPUB, Markdown, or any of the 22 supported targets from the output format list.
Convertessa converts the file locally and saves the result alongside the original. No internet connection required.
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.
