OPUS to WAV converter
Turn OPUS files into WAV for free. The conversion runs entirely in your browser, so your audios are never uploaded anywhere.
How to convert OPUS to WAV
- Add your OPUS files. Drop one or more .opus files on the box above, or tap it to pick them from your device.
- Let it convert. The first audio you convert loads the converter once (about 31 MB, then cached). After that it runs on your device; a progress bar shows how far along it is.
- Download the WAV. Press Download next to each file. Nothing was sent to a server, so close the tab and it's gone.
What is a OPUS file?
Opus is the audio codec used by WhatsApp voice notes, Discord and video calls. It sounds great at very low bitrates.
What is WAV?
WAV is uncompressed audio: exactly what the microphone or instrument produced, used in studios and for editing.
Why convert OPUS to WAV?
OPUS is great for voice notes and calls, but many players, editors and upload forms don't accept .opus files. WAV is the better choice for editing, mixing and archiving without loss; keep in mind about ten times bigger than MP3.
Will I lose quality?
No. WAV is lossless, so every sample that OPUS gave us is kept exactly.
Private by design
Most online converters upload your file to their servers. This one doesn't: the converter itself is loaded into your browser and works offline from there, so your audios never leave your phone or computer.
Questions
Is this OPUS to WAV converter free?
Yes, completely free, with no sign-up, no watermark and no daily limit.
Are my OPUS files uploaded?
No. The conversion happens inside your browser on your own device. Nothing is sent to us or anyone else.
Can I convert OPUS to WAV on iPhone or Android?
Yes, in a modern browser. Phones are slower than computers for video, and very long videos can run out of memory on older phones.
Can I convert several files at once?
Yes. Drop as many as you like; they are converted one after another and each gets its own download button.
Is there a file size limit?
No fixed limit, but your browser has to hold the whole file in memory, so files over about 2 GB may fail.
