How to convert AAC to WAV

  1. Add your .AAC file - drop it in the box above or click to browse.
  2. Convert it to .WAV in a few seconds.
  3. Download your new .WAV file.

What to expect

  • WAV is uncompressed, so a 4 MB .aac file can expand to 40+ MB as .wav - this is normal.
  • The conversion adds no extra quality loss, but cannot restore data that AAC already discarded.
  • DRM-protected .m4p files cannot be converted by any free tool; only unprotected files work.

Frequently asked questions

Does converting AAC to WAV improve audio quality?
No. The WAV stores exactly what the AAC decoder outputs. Quality lost during the original AAC encoding cannot be recovered.
Why is the WAV file so much larger than the AAC?
AAC uses lossy compression at roughly 10:1 to 15:1 compared to raw audio. WAV stores uncompressed PCM samples, so the large size difference is expected.
My file is `.m4a`, not `.aac` - does this work?
Yes. .m4a is simply AAC audio inside an MP4 container, and converters detect the real format from the file header.
Can I convert AAC to WAV on my phone?
Yes - use the free converter on this page, which works on mobile. Android users can also find dedicated audio converter apps in the Play Store.
