Convert Opus to WAV
We turn Opus into WAV right in your browser — the file never goes to a server.
What you will lose
- Title, artist and cover art will be lost: the target format does not carry them reliably.

Opus
Good at
- The best quality at low bitrates — speech stays clear at 24 kbps
- The standard for voice: messengers, calls, streams
- Free, with no licensing fees
Awkward about
- Older devices and editors do not know it
- Car stereos and consumer players usually refuse it
- Lossy — not a master format
Use it when
- Voice: a podcast, an interview, a voice message
- You need the smallest size that still sounds clear
- The file is listened to in a browser or a messenger
WAV
Good at
- Lossless and uncompressed: what was recorded is what is stored
- Opens instantly in any editor, nothing to unpack
- Works as a master for further processing
Awkward about
- Enormous: a minute of stereo is about 10 MB
- Tags exist on paper but not everything reads them
- Usually too big to send by email
Use it when
- Editing or processing is coming and quality must not drop
- A short fragment: an interface sound, a sample
- The file is for a program, not for a listener
Common questions
- Does the file get uploaded to a server?
- Yes, this pair needs the server: browsers cannot encode that format. The file and the result are deleted within a couple of hours and never shared.
- Will surround sound survive?
- Yes, WAV carries more than two channels — 5.1 stays 5.1.
- Can I get the original quality back afterwards?
- Nothing is lost, but nothing is gained either. WAV stores exactly what Opus hands over, including the gaps Opus left behind when it compressed. No tool can bring those back, and the file grows several times over. This conversion makes sense for editing, not for quality.
- How many files, and how large?
- Up to 10 files at a time, 200 MB each. No sign-up, no watermarks.
