Why convert WMA to WAV?
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 WAV 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: WAV is already selected. WAV 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 WAV, 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 WAV format (Waveform Audio File Format)
WAV is an uncompressed format: it stores raw audio, exactly like a CD. The quality is perfect but the files are large (about 10 MB per minute at CD quality). It is the reference format for audio editing, music production, transcription and professional software.
- No quality loss
- Read by every audio application
- Ideal for editing and transcription
- Very large files
- No standardized metadata (title, artist)
