Your files stay on your Mac.
Convertessa reads your .wiki markup files and writes standard OpenDocument Text (.odt) documents entirely on your Mac — no internet connection required and no files ever leave your machine. The conversion maps wiki headings, inline formatting, and structure into the .odt format and strips embedded metadata in the process. Drop a single article or an entire folder of wiki pages and Convertessa handles them all in one pass.
Drag one or more .wiki files — or a whole folder — onto Convertessa. Nothing is uploaded; every file stays on your Mac throughout.
Choose OpenDocument Text from the output list. Convertessa will write a matching .odt file for each source document.
Click Convert. Convertessa processes every file locally and saves the finished .odt documents alongside your originals or to a destination folder you specify.
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.
