Why convert WAV to OPUS?
- OPUS is more widely accepted by browsers, phones, TVs, or sharing services than the source WAV file.
- A standardized output makes it easier to archive, upload, or hand a file to someone with different software.
- Playback compatibility is usually the main reason to change a media container.
- A converted copy separates the delivery format from the original edit or camera file.
Will quality change?
Lossy OPUS 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 OPUS 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

- Skip the conversion when the destination already accepts WAV and no compatibility problem exists.
- For a one-off preview, a local viewer may be faster than creating a new delivery file.
