Your files stay on your Mac.
WavPack stores audio losslessly; Ogg Vorbis re-encodes it as compressed, open-format audio using the Vorbis codec. Convertessa decodes each .wv file and encodes it to .ogg, letting you set quality to balance file size against fidelity. Everything runs on your Mac — no upload, no account required.
Drag one .wv file or an entire folder onto Convertessa. All files in the folder are queued for batch conversion automatically.
Choose Ogg Vorbis from the output list. Set quality to control the trade-off between file size and audio fidelity.
Click Convert. Convertessa decodes each WavPack file and writes a matching .ogg file to your chosen destination folder.
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.
Yes. Drag a folder onto Convertessa or pass a directory to the CLI with convertessa ./folder/ --to ogg. Every .wv file inside is converted in one batch.
No. Convertessa runs entirely on your Mac. Your WavPack files are decoded and re-encoded locally — nothing is sent to a server.
Ogg Vorbis quality ranges from low (smaller files) to high (closer to the lossless source). A mid-range setting works well for general listening; raise it if the source material is demanding or if you hear artifacts at lower settings.
