Your files stay on your Mac.
Convertessa reads your .typ source files and renders them to RTF—the interchange format accepted by Word, Pages, and virtually every desktop word processor. Headings, paragraphs, and inline formatting are mapped to RTF constructs so your document structure arrives intact. Conversion runs entirely on your Mac; no file ever touches a server.
Drag one .typ file or an entire folder into Convertessa. The app queues every .typ file it finds.
Choose Rich Text from the output list to target .rtf output. Set quality to tune output fidelity.
Click Convert. Convertessa renders each Typst source and writes an .rtf file ready to open in any word processor.
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.
