Your files stay on your Mac.
WavPack stores audio in a lossless compressed container that many players and editors don't natively support. Converting to WAV decodes the compressed stream back to standard PCM, producing an uncompressed file that works in any audio tool or editor. The conversion runs entirely on your Mac — no files are uploaded anywhere.
Drag one or more .wv files into Convertessa, or drop a whole folder to queue an entire batch at once.
Pick WAV from the output format list. Convertessa will decode each lossless WavPack stream to uncompressed PCM WAV.
Click Convert. Convertessa processes every file locally and writes standard .wav files ready for any audio editor or media player.
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.

No. WavPack is a lossless format, so decoding it to WAV produces a bit-for-bit identical PCM stream — no audio data is lost or altered in the process.
Yes. Drop a folder onto Convertessa or run convertessa *.wv --to wav in your terminal to batch-convert every WavPack file in one pass.
No. Convertessa converts everything locally on your Mac. Your .wv files never leave your machine — no upload step, no internet connection required.
