Convert AAC to WMA
Updated Jul 2026
AAC is the compressed audio format used by Apple Music, iTunes, and most phones, while WMA is the older format built for Windows Media Player and some Windows-only software. To convert AAC to WMA, open the file in a converter and export it as WMA. Doing this on your own computer means the audio file never has to leave your machine.

How to convert AAC to WMA
- Open Morphjet and drag in the AAC file, or a whole folder of them, at once.
- Choose WMA as the output format.
- Convert. The WMA files are written right next to your originals, and nothing is uploaded anywhere.
AAC vs WMA: what actually changes
| AAC | WMA | |
|---|---|---|
| Compatibility | Wide, plays on iPhone, Android, and most modern apps | Narrower, mainly Windows Media Player and older Windows software |
| File size | Compact for its quality level | Similar size at a matching bitrate |
| Quality at a given bitrate | Generally more efficient | Usually needs a higher bitrate to sound as good |
| Streaming and app support | Used by Apple Music, YouTube, and most streaming services | Rarely used by modern streaming or web apps |
| Song tags (artist, album, artwork) | Yes | Yes, though some older Windows programs and car stereos read tags differently |
When to convert, and when not to
Convert AAC to WMA when you're feeding audio into an older Windows program, a car stereo, or a piece of hardware that specifically expects WMA.
Keep the AAC file if it already plays fine on your phone, in iTunes, or in a modern app, since AAC is lossy already and re-encoding it into another lossy format just adds a second round of quality loss for no real benefit.
Why not just use an online converter?
Music you've bought, ripped, or recorded yourself is still personal, and a lot of online converters ask you to upload the whole audio file to their server just to change its format. Morphjet does the conversion on your own computer, so your files, and whatever's in them, never go anywhere near someone else's server.
Questions
Does converting AAC to WMA lose quality?
A little. Both are lossy formats, so re-encoding one into the other means a second round of compression on top of the first. For most listening it won't be noticeable, but it's not a lossless swap.
Why would I need WMA instead of AAC today?
Mostly for older Windows software, some car stereos, or hardware media players that were built around Windows Media Player and never added AAC support.
Will the converted file keep the artist, album, and artwork info?
Usually. The tags carry over in the conversion, though some older Windows programs or hardware players can be inconsistent about showing artwork.
Can I convert AAC to WMA without uploading the file?
Yes. A desktop app like Morphjet converts the file locally, so it never travels over the internet. You can do it with your wifi off.
Will a WMA file play on an iPhone or Mac?
Not natively. WMA support on Apple devices is limited, so if you're moving audio the other way, from WMA to AAC, is usually the better direction.
