Your files stay on your Mac.
AsciiDoc is a rich plain-text format built for technical documentation. Textile is a lightweight markup syntax used in project management tools like Redmine and many content management systems. Convertessa reads your .adoc source and rewrites it as Textile — headings, lists, bold, italic, inline code, and links all translated to their Textile equivalents.
Drag a single .adoc file or an entire folder into Convertessa. Batch mode processes every document in the folder in one pass.
Pick Textile from the output format list. Convertessa maps AsciiDoc block structure and inline markup to the closest Textile equivalents.
Click Convert. Your Textile files land next to the originals. Nothing was uploaded — all processing ran locally on 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.

New formats, new features, and fixes — every release, on the record.
Convertessa translates the most common AsciiDoc constructs — headings, ordered and unordered lists, bold, italic, inline code, and hyperlinks — to their Textile counterparts. Highly AsciiDoc-specific blocks such as admonitions and sidebars are rendered as plain paragraphs.
Yes. Drop the folder onto Convertessa or run convertessa ./docs/ --to textile in the terminal. Every .adoc file in the folder is converted and saved as a .textile file beside the original.
No. Convertessa runs entirely on your Mac. Files never leave your machine — there is no upload step and no internet connection required.
