Free M4A to WAV converter

Why convert M4A to WAV?

People convert M4A to WAV because M4A is Apple’s audio wrapper, and plenty of players skip straight past it, while WAV is raw, uncompressed audio that every editor and DAW imports without fuss.

How to convert M4A to WAV

1. Choose your M4A file. Drop it on the box above, or tap to browse. You can pick several files at once.
2. Confirm the target is .wav. It is preselected when your browser can encode it; otherwise the closest available target is chosen. Adjust quality, size or the other options if you want to.
3. Convert and download. Press Convert, then Download. Your file stays on your device the whole time.

What is a .m4a file?

M4A holds AAC audio in an MP4 container — the format of iTunes purchases, Apple Music downloads and iPhone voice memos. At the same bitrate it sounds better than MP3, though a few older devices still refuse it.

What is a .wav file?

WAV is uncompressed audio: the raw samples, exactly as recorded, with no quality lost and no processing applied. That makes it the format for recording, editing and archiving — and a poor one for sharing, since a few minutes runs to tens of megabytes.

What to expect from this conversion

The audio is decoded and re-encoded with the target codec. Choose 192 kbps or higher for music; speech is perfectly clear at less. Converting between two lossy formats always loses a little, so work from the original where you can. WAV is uncompressed, so expect roughly 10 MB per minute of stereo sound.

Is it private?

Yes, by design. Every conversion happens inside your own browser using your device’s processor — there is no server that receives your M4A file, so there is nothing for anyone to store, scan or leak. You can confirm it yourself: open your browser’s developer tools, watch the Network tab while you convert, and you will see no upload.
