Frequently asked questions
Is this WAV to OPUS converter free?+
Yes, with no watermark, no account, and no daily limit.
Is my audio file uploaded anywhere?+
No — conversion runs locally using your browser's own built-in media codecs, entirely inside your browser tab.
Will I lose audio quality?+
Converting between compressed formats can lose a small amount of quality; converting to a lossless format like WAV or FLAC won't.
Is there a maximum file size?+
There's no fixed file-size limit since nothing is uploaded to a server. Processing time scales with the track's length rather than a hard cutoff.
How do I convert WAV to OPUS?+
Drop your WAV file into the box above — it's decoded and re-encoded as OPUS automatically, with a download ready in seconds.
About WAV and OPUS
What is WAV?
WAV stores audio with no compression at all, which is why it's the standard format in recording studios and audio editing software.
Full WAV format guide →What is OPUS?
Opus is a modern, royalty-free codec built for both music and speech, widely used in video calls and voice messaging.
Full OPUS format guide →WAV and OPUS solve different problems. WAV is great for recording and mixing, but OPUS pulls ahead when you need excellent quality at low bitrates. If that's the situation you're in, converting is worth it.
How it works
- 1
Drop your file in
Drag your audio onto the box above, or click it to browse — there's no account to create and no upload to wait on.

Download the result
Your browser processes everything locally and hands you a download link the moment it's done — nothing was ever sent to a server.
Is it private?
Everything happens locally, inside this browser tab. Your audio is read from disk, processed with WebAssembly running on your own device, and handed back to you as a download — it's never transmitted anywhere, so there's nothing to intercept and nothing stored on a server.
Common use cases
- Voice and video calls
- Streaming at low bandwidth
- Prepping a podcast episode for a hosting platform
- Fitting a voice memo under a messaging app's size limit

About WAV files+
WAV stores audio with no compression at all, which is why it's the standard format in recording studios and audio editing software.
WAV (Waveform Audio File Format) was created jointly by Microsoft and IBM in the early 1990s as a simple container for raw, uncompressed audio samples. Storing audio with no compression means there's never any generation loss from repeated saving and no decoding overhead when a program reads it, both of which matter enormously in a studio environment where a track might be opened, edited, and re-saved dozens of times before it's finished. The obvious tradeoff is size — a few minutes of CD-quality stereo audio can easily run to tens of megabytes — so WAV is rarely the format anyone actually distributes a finished track in.
How to open a WAV file
Opens readily in Any media player, Any web browser. For real editing, use Audacity (free), Pro Tools, Adobe Audition.
Good for
- lossless, full-fidelity audio
- no decoding overhead, ideal for editing
Watch out for
- very large files — roughly 10MB per minute of CD-quality stereo audio
About OPUS files+
Opus is a modern, royalty-free codec built for both music and speech, widely used in video calls and voice messaging.
Opus was developed by the IETF and the Xiph.Org Foundation to unify what used to be two separate problems — speech codecs and music codecs — into a single format that performs well at both, with very low latency. That low latency and strong quality at low bitrates is exactly why it's become the default codec behind most modern video and voice calling: WhatsApp, Discord, Google Meet, and many others all rely on it under the hood, even when users never see the format name at all.
How to open a OPUS file
Opens readily in VLC Media Player, Most modern browsers and media players. For real editing, use Audacity (with recent versions).
Good for
- excellent quality at low bitrates
- low latency, ideal for real-time audio
Watch out for
- less common as a general music-library format
