Your files stay on your Mac.
Convertessa reads each OpenDocument Text file and renders it to a fixed-layout PDF, preserving text, tables, and embedded images exactly as they appear in the source. Metadata embedded in the ODT file is stripped from the output. Processing runs entirely on your Mac — no upload, no server.
Drag one ODT file or an entire folder of ODT files onto Convertessa to load them for conversion.
Choose PDF from the output format list. Set quality to control the balance between file size and rendering fidelity.
Convertessa renders every file locally and saves converted PDFs alongside the originals — nothing is uploaded.
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.
