M4A to WAV Converter

Convert M4A files to WAV. Free, without uploading.

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

WAV is uncompressed audio: no quality loss, but large files. Editing and recording software use it a lot. WAV 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 WAV file.
