How to convert M4A to WV
- Add your .M4A file - drop it in the box above or click to browse.
- Convert it to .WV in a few seconds.
- Download your new .WV file.
What to expect
- Lossless WV preserves the source exactly, but a lossy AAC M4A stays lossy in content; nothing AAC dropped is recovered.
- Expect a substantially larger file than the original M4A.
- Broad software support exists, but portable-device support for WavPack is narrower than for FLAC or MP3.
Frequently asked questions
Is the WavPack output truly lossless?
WavPack (WV) is a lossless codec, but it can only preserve the audio it is given. Since M4A is usually lossy AAC, the WV faithfully stores that already-lossy audio and cannot restore what AAC removed.
Why convert M4A to WV?
WavPack is a free, open-source lossless format, so people convert to archive audio without further loss or to use players and libraries that favor WV. It typically stores sound at roughly 40-60% of WAV size.
Where will a WV file play?
VLC and foobar2000 on Windows, Cog or VLC on macOS, and most Linux players via FFmpeg open WV. It is less common on portable hardware than FLAC.
Will the file get bigger?
Yes. Lossless WV files are much larger than the lossy M4A, since they stop discarding data from the point of conversion onward.
