Free Opus (.opus) to WAV (.wav) converter running entirely in your browser — with bitrate, sample rate and channel control. No upload, no signup.
MP3 · WAV · M4A · AAC · OGG · Opus · FLAC · WebM · AIFF
Opus is the current state of the art: better than MP3 and AAC at nearly every bitrate, and the codec behind WhatsApp voice notes, Discord and WebRTC. It is young enough that plenty of players and editors still cannot open it.
Best for: Voice notes and real-time audio; convert for editors and players.
WAV stores uncompressed PCM samples: exactly what came off the converter, no encoder in the way. Files are large — roughly 10 MB per minute of CD-quality stereo — but editing, mastering and archiving all want that fidelity.
Best for: Editing, mastering and any workflow that must not re-compress.
Yes — unlimited, watermark-free and without an account. Conversion runs on your own machine, so there is no per-file cost to pass on.
No. Your browser decodes and re-encodes the audio locally; nothing is transmitted, which matters for voice notes, interviews and unreleased tracks.
WAV is uncompressed PCM, so the output is exactly what the decoder produced — nothing is thrown away. Files are large: roughly 10 MB per minute of CD-quality stereo.
Yes. Drop a whole batch — each file is processed in turn and the results can be downloaded individually or together as a ZIP.
Opus tags, comments and cover artwork are separate from the decoded samples and are not carried into the conversion. The WAV writer creates a fresh 16-bit PCM file containing audio samples only, so keep the source if those annotations matter.
