Your files stay on your Mac.
Convertessa decodes each Ogg Vorbis file and writes the audio samples into a WavPack lossless container. Every sample present in the decoded Ogg is preserved exactly — no additional generation loss is introduced. Processing happens entirely on your Mac; files never leave your machine.
Drag one .ogg file or an entire folder of them onto Convertessa. Batch conversion processes every file in one pass.
Pick WavPack from the output format list. Convertessa targets the .wv format and writes a standard WavPack lossless stream.
Click Convert. Convertessa decodes each Ogg Vorbis file and encodes the raw audio into WavPack, writing the output 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.

No. Ogg Vorbis is a lossy format, so some audio information was discarded when the file was originally encoded. Converting to WavPack preserves every sample in the decoded Ogg exactly — it introduces no further loss — but it cannot recover data that was already gone.
Yes. Drop a folder onto Convertessa and it converts every .ogg file inside in a single batch. You can also use the CLI: convertessa /path/to/folder/*.ogg --to wv.
Yes. Convertessa removes embedded metadata (tags, artwork, and other fields) from audio files during conversion, so the .wv output contains only the audio stream.
