Why convert WMA to M4R?
- Conversion is useful when the destination has a strict format requirement.
- A converted copy keeps the original file intact for comparison and future edits.
- The output can be tested in the destination workflow before the original is archived.
- A separate copy makes it easier to compare the old and new behavior.
Will quality change?
Review the result in the destination application, especially for complex files, metadata, and formatting. The original source remains the best reference for comparison.

When not to convert
- Do not overwrite the source; keep both versions until the output has been approved.
- Avoid repeated lossy conversions when quality matters; start from the highest-quality source available.
- If the file contains sensitive data, review the processing model before uploading it to a server.
