Quick answer: To convert WV to OPUS, add the WV file to the iHateFiles WV to OPUS converter and press Convert. The conversion runs in your browser, so the file is never uploaded, and it is free with no sign-up, watermark or size limit. WV is a format most software has stopped opening. OPUS is not.
Should you convert WV to OPUS?
Do this to make a lossless recording small enough to share or carry around. Keep the WV as the master copy.
WV is lossless and OPUS is not
This is the conversion lossy formats were designed for: from 5 to 7 MB per minute to 0.25 to 1 MB. At 192 kbps or more almost nobody can hear the difference in music. Keep the WV as your master if you might need to convert again.
Where the OPUS will play
OPUS plays on browsers, Android, WhatsApp and Discord, but not many car stereos or older players.

What usually goes wrong
About the WV. If you have a .wv and a .wvc, the second is the correction file. Without it you have only the lossy version.
About the OPUS. Opus at 64 kbps sounds better than MP3 at 128, so the bitrate you are used to is roughly double what you need here.
How to convert WV to OPUS
- Add your WV file. It is read from your disk and stays there.
- Check the settings. The output format is already set to OPUS.
- Press convert and the OPUS file is saved back to your device.
Questions
How do I convert WV to OPUS?
Open this page, add your WV file, and press convert. The file is decoded and re-encoded by your own browser and saved back to your device. Nothing is uploaded.
Is this WV to OPUS converter free?
Yes, completely. There is no account, no sign-in, no watermark and no daily limit, because there is no server doing the work. Your own device does it.
Are my files uploaded anywhere?
No. There is no upload endpoint. The conversion runs inside this browser tab, so your file never leaves your device. You can open your browser's network panel and watch: nothing carrying your file is sent.
Is there a file size limit?
No fixed limit. Because the work happens on your machine there is no server quota. The only ceiling is your own device's memory, which for video means very large files may be slow.
Will converting to OPUS lose quality?
OPUS is a lossy format, so some detail is discarded. The quality control on this page decides how much. The default is set high enough that most people cannot see the difference.
Can I convert several WV files at once?
Yes. Add as many as you like and they are converted one after another, then offered as a single ZIP.
