How to convert M4A to WAV

  1. Add your M4A files. Drag them onto the box above or click to choose them. You can add several at once.
  2. Check the target is WAV. It is already selected. Adjust the quality under Options if you want.
  3. Click Convert. The conversion runs in your browser — the file is never uploaded to a server.
  4. Download the WAV. When it finishes, click Download on each file.

When you need this

Bringing voice memos or interviews recorded on an iPhone into Audacity, Pro Tools, Premiere or a transcription tool that wants WAV.

M4A vs WAV

M4A

AAC audio in an MPEG-4 container — the format Apple uses for iTunes, Voice Memos and GarageBand exports. Better quality than MP3 at the same bitrate.

Best for: iPhone, Mac, Apple Music and iTunes libraries.

WAV

Uncompressed PCM audio. Every sample is stored as-is, so there is nothing to decode and nothing lost — at the cost of roughly 10 MB per minute of stereo.

Best for: video editors, DAWs, samplers, broadcast and any tool that wants raw audio.

Will I lose quality?

Converting M4A to WAV does not bring back what the M4A compression already removed: the WAV will sound exactly like the M4A, only bigger. Do it when an app or device asks for WAV, not to improve the sound. The good news is that nothing more is lost either.

Have a link instead of a file?

Frequently Asked Questions

How do I convert M4A to WAV?
Drag the M4A file onto the box above, check the target is WAV and click Convert. As soon as it finishes a Download button appears. Nothing to install, no account needed.
Is it free to convert M4A to WAV?
Yes, completely: no sign-up, no daily limit and no watermark. Your own browser does the conversion, so it costs us nothing and there is no reason to charge for it.
Are my files uploaded to a server?
No. The converter runs inside your browser: the file is read and converted on your device and never leaves it. That is why it is safe for private or work recordings.
Will I lose quality?
Converting M4A to WAV does not bring back what the M4A compression already removed: the WAV will sound exactly like the M4A, only bigger. Do it when an app or device asks for WAV, not to improve the sound. The good news is that nothing more is lost either.
Is there a file size limit?
Up to 1 GB per file. The limit is not a business one but the browser’s: all the work happens in its memory, and above that size some browsers close the tab. On a phone, stay well below it.
Can I convert several files at once?
Yes. Add as many M4A files as you like and they are converted one after another with a single click. Each one can go to a different format.
