Convert AAC to WAV
Updated Jul 2026
AAC is the compressed audio format used by Apple devices and most streaming services, and WAV is the uncompressed format that audio editing and production software expects. To convert AAC to WAV, open the file in a converter and export it as WAV. Doing this on your own computer keeps the recording off other people's servers.

How to convert AAC to WAV
- Open Morphjet and drag in the AAC file you want to convert. Add one file or a whole folder at once.
- Choose WAV as the output format.
- Convert. The WAV file is written next to your original, and nothing leaves your machine.
AAC vs WAV: what actually changes
| AAC | WAV | |
|---|---|---|
| File size | Small, compressed | Much larger, often 5 to 10 times bigger |
| Quality | Lossy, some detail discarded when it was first encoded | Lossless, but converting from AAC can't bring back what AAC already threw away |
| Opens everywhere | Yes on Apple devices and modern apps, patchy on older or professional audio gear | Yes, close to universal, including older hardware and studio software |
| Good for editing | No, re-saving a compressed file loses a bit more each time | Yes, the standard format for editing without extra loss |
| Keeps track info (artist, title) | Yes, tags are common | Inconsistent, many tools drop or ignore them |
When to convert, and when not to
Convert AAC to WAV when you need to bring audio into editing or production software, load it onto hardware that only reads uncompressed files, or work with it in a tool that doesn't handle AAC well.
Keep the AAC file if you're just listening to it or storing it, since WAV won't sound any better and takes up far more space for no real benefit.
Why not just use an online converter?
Voice memos, recordings, and personal audio in AAC often aren't meant for anyone else to hear. An online converter means that file travels to a server you don't control before you get it back. Converting on your own computer means the recording never leaves your machine.
Questions
Does converting AAC to WAV improve the sound quality?
No. AAC already discarded some audio detail when it was encoded, and that's permanent. Converting to WAV just stores what's left in an uncompressed file, it doesn't restore anything.
Why does the WAV file end up so much bigger?
WAV doesn't compress the audio at all, so it stores every sample directly. A three-minute AAC track might be a few megabytes, while the same audio as WAV can run to several tens of megabytes.
Will the WAV keep the artist and title tags from the AAC file?
Not reliably. WAV's support for that kind of metadata is inconsistent across software, so track info often gets dropped during conversion even though the audio itself is unaffected.
Can I convert AAC to WAV without uploading the file anywhere?
Yes. A desktop app like Morphjet converts the file on your own computer, so it's never sent over the internet. You can do it with your wifi off.
Why would I need WAV instead of just using the AAC file?
Most audio editing and production software expects uncompressed audio, and some older or professional hardware won't read AAC at all. WAV is the safe, widely readable choice for that kind of work.
