Before converting OPUS
OPUS is used in messaging and is optimized for speech. Keep the original: converting to MP3 adds lossy compression and does not guarantee a smaller file.
File processing
The file is uploaded and processed on the server. Processing deletes the original when it finishes; the MP3 is deleted after a complete download or through temporary-file cleanup. Technical conversion data is logged.
Frequently asked questions
Does conversion improve a voice recording?
It cannot recover lost information or increase the volume. If the result sounds worse, return to the original and try another bitrate.
Why is my OPUS file rejected?
The file must contain a readable audio track. If the download is incomplete, save the original again before uploading it.
