M4A to WV Converter

Convert M4A files to WV. Free, without uploading.

This tool converts M4A files to WV. M4A is Apple’s format for AAC audio. iPhone voice memos and iTunes use it; it is smaller than MP3 at the same quality.

WavPack lossless audio. WV is lossless, so the audio keeps the quality it has in the M4A file.

Conversion runs on your device; your file is never sent to a server. The components download once on first use, and later conversions start right away.

How to use

1. Choose the M4A file, drag it in, or paste its link.
2. Choose the audio quality; optionally enter a start and end time.
3. Press "Convert" and download the WV file.
