How do I convert M4A to WAV?

M4A uses Apple's compressed AAC codec, but audio editors, mastering tools, and CD software prefer to work with uncompressed WAV. Converting to WAV gives you a raw PCM file those programs handle cleanly.

Your WAV is ready Download WAV

Upload your M4A file and choose WAV as the output, then download it. M4A is a compressed lossy format and WAV is uncompressed, so the WAV will be much larger. It will not sound better than the M4A, since WAV decompresses the audio but cannot restore detail already lost in compression.

How it works

1

Upload your M4A file

Select or drag in the M4A audio you want to convert to WAV.

2

Choose WAV as the output

Set WAV as the target so the audio is decompressed into uncompressed PCM.

3

Download your WAV

Save the WAV, ready to drop into a DAW, editor, or CD burning software.

Frequently asked questions

No. M4A is lossy, so detail discarded during its compression is gone. Converting to WAV decompresses the audio into a lossless container but cannot add back anything the M4A already lost.
WAV stores audio uncompressed, while M4A is compressed. A WAV can easily be ten times the size of the M4A it came from, since it keeps every sample as raw data.
Convert when you need to edit, master, or burn to CD. Audio software works most reliably with uncompressed PCM and avoids re-compression artifacts during editing.
Yes. WAV is the most widely accepted format in DAWs and editors, so a WAV made from your M4A drops in without compatibility issues.
No. The conversion runs online with no signup and nothing to install, and your file is deleted after processing.
