Your files stay on your Mac.
Convertessa reads your Typst source files and renders them as OpenDocument Text (.odt) documents — processing happens entirely on your Mac, no upload required. Drop a whole folder to batch-convert every .typ file in one pass. Set quality before export to control output fidelity.
Drag one .typ file or an entire folder onto Convertessa. Nothing is uploaded — every file is read and processed locally on your Mac.
Choose OpenDocument Text from the output list. Set quality to control output fidelity, then confirm your selection.
Click Convert. Convertessa processes each file offline and saves the resulting .odt documents alongside your originals.
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.
No. Convertessa runs entirely offline. Every .typ file is read and converted locally — nothing is sent to any server.
Yes. Drop a folder onto Convertessa or run convertessa *.typ --to odt in your terminal to batch-convert every Typst file in one pass.
The quality slider controls the output fidelity of the exported OpenDocument Text file. Lower values produce smaller files; higher values preserve more detail from the original Typst layout.
