Why convert WMA to AIFF?
Your old CDs ripped with Windows Media Player or the recordings from an old voice recorder are in WMA, an abandoned format that no longer opens on Mac, iPhone or Android. Converting them to AIFF makes them playable forever.
How to do it, step by step
- Drop your WMA fileinto the area at the top of the page (or several files at once). On mobile, tap the area and pick the file from your apps.
- Check the output format: AIFF is already selected. AIFF is a lossless format: there is no quality setting, the sound is reproduced identically. The file will be noticeably larger than a compressed format.
- Start the conversion.The FFmpeg engine loads once (≈ 10 MB), then each file is processed in a few seconds without leaving your device.
- Download your AIFF, directly or as a .zip if you converted several files. The name and metadata (title, artist, cover art) are preserved.
The WMA format (Windows Media Audio)
WMA is Microsoft's old audio format, produced by Windows Media Player and old recorders. It is now abandoned and increasingly hard to play, especially on Mac, iPhone and Android. Converting it to MP3 is the only way to future-proof it.
- Still playable on Windows
- Abandoned format
- Unplayable on Apple without extra software
- Possible DRM on old purchases
The AIFF format (Audio Interchange File Format)
AIFF is Apple's equivalent of WAV: uncompressed audio, perfect quality, large files. It is produced by Logic Pro, GarageBand and iTunes (CD import as AIFF). Outside the Mac, it often causes playback problems.
- Lossless quality
- Supports metadata (unlike WAV)
- Very large
- Rarely played outside the Mac
