Your files stay on your Mac.
Convertessa reads your .typ source files and rewrites the markup as Textile — headings, emphasis, links, and lists translated to their Textile equivalents. Everything runs on your Mac; no file is ever uploaded to a server. Batch mode lets you convert an entire folder of Typst documents in one pass.
Drag one .typ file or a whole folder into Convertessa. Batch mode processes every .typ document at once.
Choose Textile from the output list. Convertessa maps Typst headings, bold, italic, links, and lists to their Textile counterparts.
Click Convert. Convertessa rewrites the markup locally and saves a .textile file alongside each original — nothing leaves 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.

Yes. Drop a folder onto Convertessa or run convertessa ./folder/ --to textile in the terminal to convert every .typ file in the directory in one pass.
