About Waveform Audio File Format
Lossless, straightforward to edit, and ideal for production, mastering, and archival work. Very large files compared with compressed audio; metadata and codec support vary by application.
Format referenceWhy convert WMA to WAV?
- The result can be reviewed without changing the file that other people still use.
- WAV is more appropriate for the target application, device, or delivery channel than WMA.
- Compatibility is the main reason to convert when another person or service cannot open the source.
- The new format may support a feature the source container does not.
Will quality change?
The WAV output uses a lossless container, but it cannot recover detail already lost in a compressed WMA. File size usually increases. Check a sample before processing a large batch.

When not to convert

- Do not use a converted file as the legal or signed original when signatures or metadata must be preserved.
