Why convert AIFF to M4R?

  • 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.
  • M4R is more appropriate for the target application, device, or delivery channel than AIFF.
  • Compatibility is the main reason to convert when another person or service cannot open the source.

Will quality change?

Review the result in the destination application, especially for complex files, metadata, and formatting. Keep the source if you may need to adjust the conversion later.

The file is processed on the server because the conversion requires a server-side engine or a utility operation.

  • AIFF features without a direct M4R equivalent may not survive the conversion.
  • Review the converted file in the destination application before deleting the source.
  • Batch results should be spot-checked before publication or delivery.

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

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