Why convert MID to WMA?
- WMA is more appropriate for the target application, device, or delivery channel than MID.
- 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.
- The result can be reviewed without changing the file that other people still use.
Will quality change?
Lossy WMA output reduces file size by discarding some audio information. Use the original master for further editing. Keep the source if you may need to adjust the conversion later.

Platform compatibility
The output is a WMA file. Use an application or device that accepts that format, and test the result on the destination platform if compatibility is critical.
When not to convert
- Do not convert when the original MID must remain the only editable or archival copy.
- Skip the conversion when the destination already accepts MID and no compatibility problem exists.
- For a one-off preview, a local viewer may be faster than creating a new delivery file.
