- Review the output before replacing the original, especially for forms, annotations, or embedded objects.

MP3 works in all current major browsers. Open the result in the app where it will be used, and keep the source AUDIO/* for comparison.
When not to convert
- Skip the conversion when the destination already accepts AUDIO/* and no compatibility problem exists.
- For a one-off preview, a local viewer may be faster than creating a new delivery file.
- If MP3 support is uncertain on the destination device, test a sample before processing a large batch.
