Why convert MP2 to M4R?
- A separate copy makes it easier to compare the old and new behavior.
- 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.
Will quality change?
The output is generated by the M4R conversion path rather than copied byte-for-byte. Review the file in the application where it will be used.

- Conversion cannot restore detail that the source format already discarded.
- Complex, encrypted, or unusually structured files may need manual review.
Platform compatibility
The output is a M4R 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
- If the file contains sensitive data, review the processing model before uploading it to a server.
- Do not convert when the original MP2 must remain the only editable or archival copy.
- Skip the conversion when the destination already accepts MP2 and no compatibility problem exists.
