Your files stay on your Mac.
Converting an OpenDocument Text file to Typst produces a .typ source file you can open in any text editor, track in version control, and compile with the Typst toolchain. Document structure — headings, paragraphs, bold, italic, and lists — maps to Typst markup automatically. The result is a clean, human-readable source file ready for further editing or publication.
Drag one or more .odt files into Convertessa, or select a whole folder. Files never leave your Mac — conversion runs entirely offline.
Choose Typst from the output format list. Convertessa will produce a .typ markup file for each source document.
Click Convert. Each OpenDocument Text file becomes a Typst source file, ready to open in your editor or compile with the Typst CLI.
Images, audio, video, documents, archives and eBooks — all converted natively, right on your Mac.
