Your files stay on your Mac.
Convertessa rewrites Textile markup into Typst source syntax—headings, emphasis, lists, links, and inline code all land in their Typst equivalents. The conversion runs entirely on your Mac; files never leave your machine. Drop a single file or a whole folder and get clean .typ output ready to compile.
Drag one .textile file or an entire folder onto Convertessa. The app queues every file in the selection.
Pick Typst from the output format list. Convertessa maps each Textile construct—headings, emphasis, lists, links, blockquotes—to the matching Typst syntax.
Click Convert. Your .typ files appear alongside the originals, or in any destination folder you choose, without uploading anything.
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, paragraphs, bold, italic, inline code, bullet and numbered lists, blockquotes, and hyperlinks are all translated to their Typst equivalents. Document structure is preserved; only the markup syntax changes.
No. Convertessa converts Textile to Typst entirely on your Mac. Nothing is uploaded at any point.
Yes. Drag a folder onto Convertessa or run convertessa ./folder/ --to typ in the terminal. Every .textile file in the folder is converted in one pass.
