Convert OPUS to WAV
Turn an .opus voice note into an uncompressed WAV that editors, DAWs, and transcription tools accept without complaint. The conversion happens on your machine, in this tab, with no upload step at all.
Why convert OPUS to WAV?
WAV is the format audio software trusts. Editors like Audacity and Pro Tools, plus many transcription services and legal or HR workflows, expect plain PCM audio rather than an Ogg file from WhatsApp. Journalists converting interview recordings, podcasters cleaning up a remote guest's Discord audio, and anyone handing a voice memo to a professional editor hit this wall constantly. Converting to WAV removes the format question entirely, because plain PCM is the one thing editors, DAWs, and hardware all agree on.
Quality and file size
Be clear about what this conversion does: it decodes the audio, it does not enhance it. Opus is lossy, and unpacking it to WAV cannot bring back anything the original compression discarded. What you get is a faithful, uncompressed copy of exactly how the .opus file sounds right now, at roughly 10 MB per minute at CD quality. That size is the honest price of a file that edits cleanly, scrubs instantly, and opens in practically anything.
OPUS to WAV: common questions
Does converting to WAV improve the audio quality?
No, and any tool that claims otherwise is misleading you. The WAV is an exact decode of what the Opus file already contains, nothing more. The reasons to do it are editing and compatibility, not fidelity.
How big will the WAV file be?
Expect around 10 MB per minute at CD quality, so a 3 minute voice note becomes roughly a 30 MB WAV. That is normal for uncompressed PCM.
Is this safe for a private or legally sensitive recording?
Yes. Nothing is uploaded, because FFmpeg runs inside your browser via WebAssembly. The recording stays on your device from start to finish, and we never see it, store it, or train on it.
Why do transcription tools reject my .opus file in the first place?
Many of them only accept a short list of formats, usually WAV and MP3. Opus support is still patchy outside of messaging apps and browsers, so WAV is the safest thing to hand them.
