How do I convert WAV to Opus?

Upload your WAV file using the box above, confirm Opus as the output format, then select Convert. The converted file is ready to download as soon as processing finishes — usually in a few seconds.

Is converting WAV to OPUS free?

Yes, and there is nothing to sign up for. Every conversion route is free on every plan — paying raises limits such as file size and how many conversions you get, and removes advertising. It never unlocks a format, adds a watermark or degrades the output.

Will the quality change when converting to Opus?

OPUS uses lossy compression, so some data is discarded to keep the file small. The default quality setting is tuned to be visually or audibly transparent for most material, and you can raise it in the conversion settings.

What happens to my file afterwards?

The uploaded file is deleted as soon as the conversion completes, and the converted file is removed automatically once its retention window ends. Download links are signed and expire within minutes.

About WAV and OPUS

WAV .wav

Raw uncompressed audio samples in a thin container. Exactly what came off the recorder, at roughly 10 MB per minute of stereo CD-quality sound.

Good for

Bit-for-bit perfect — nothing is discarded
No decoding overhead, so editors handle it fastest
The standard working format for recording and editing

Trade-offs

Very large — around 10 MB per minute
No built-in tags for artist or album
Impractical for distribution or streaming

audio/wav

Opus .opus

The current state of the art in lossy audio, standardised by the IETF. It outperforms MP3 and AAC across the range and is dramatically better at low bitrates.

Good for

Best quality per byte of any format here
Excellent for speech as well as music
Open, royalty-free, and low latency

Trade-offs

Lossy
Older devices and some players will not open it
Less familiar, so people distrust the file extension

What changes when you convert WAV to OPUS

This is a re-encode, not a repackage

Some tools can move a stream into a different container untouched when the codecs happen to line up. We do not — every job here is decoded and encoded again, so the conversion takes time in proportion to the length of the file and costs a small amount of quality even where a repackage would have been possible. In exchange the output is predictable: it plays everywhere, rather than inheriting whatever the source happened to contain.

What your OPUS will contain

The output is Opus — encoded with Vorbis at 192 kbps by default. Vorbis is royalty-free and holds up slightly better than MP3 at the same bitrate, though Opus has largely superseded it for new work.

This step is irreversible

WAV holds every sample; OPUS keeps a close approximation. The file gets dramatically smaller, and converting back later will not undo it. Keep the WAV original if it is a master you will work from again.

Tags may not survive intact

WAV stores its metadata as RIFF INFO chunks, which many players ignore entirely, and OPUS uses Vorbis comments. Standard fields such as title, artist and album normally map across. Anything without an equivalent on the other side — unusual custom fields, some ratings and play counts, occasionally embedded artwork — has nowhere to go. Check the tags before deleting the original if your library depends on them.
