Your files stay on your Mac.
Convertessa reads your AsciiDoc source and rewrites every structural element — headings, lists, tables, code blocks, and cross-references — into the MediaWiki markup dialect used by Wikipedia and compatible wiki engines. The conversion runs entirely on your Mac: no file is sent to a server. Drop a single document or an entire folder and all files are processed in one pass.
Drag one .adoc file or a whole folder of them onto Convertessa. The app lists every file it finds so you can review before converting.
Select MediaWiki as the target format. Convertessa will map AsciiDoc's heading levels, list styles, table syntax, inline formatting, and code blocks to their MediaWiki equivalents.
Click Convert. Each .adoc file becomes a .wiki file in the same folder, ready to paste into your wiki editor or upload via the MediaWiki API.
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.
Headings, ordered and unordered lists, tables, bold, italic, monospace, code blocks, and hyperlinks are all remapped to their MediaWiki equivalents. Embedded images become [[File:…]] references. AsciiDoc-specific directives that have no MediaWiki counterpart are preserved as HTML comments so nothing is silently dropped.
No. Convertessa runs the entire conversion locally. Your .adoc files are read from disk, transformed in memory, and written back to disk — nothing is uploaded or transmitted.
Yes. Drop a folder onto Convertessa or pass a directory path on the command line (convertessa ./docs/ --to wiki) and every .adoc file inside is converted in a single batch. Output files are placed alongside their sources.
