Opus (.opus) · Max 20 MB

"Online converter" normally means uploading your file to someone's server, waiting in a queue, and downloading the result. This page inverts that: it loads FFmpeg compiled to WebAssembly into your browser and does the work on your own machine. You keep the convenience of online — nothing to install, works on any OS — without the upload.

Expect growth, not shrinkage: about 10 MB per minute versus 0.5. That's the price of an uncompressed or lossless container, and it buys you an editing chain that costs nothing further. That matters here, because transfer is where server-based converters spend most of their time. With no upload and no download of the result, what's left is just the conversion itself: usually a second or two.

Opus files typically come from Discord recordings, WhatsApp and Telegram voice messages, and WebRTC captures — and Opus is the best lossy codec in use, but it lives inside apps — car stereos, older iPhones and smart speakers won't play it. Don't expect an upgrade: WAV faithfully preserves whatever you give it, including everything Opus already threw away. The value is a loss-free chain from here on, not restoration.

Because it's a web page rather than software, the same converter runs on Windows, macOS, Linux, ChromeOS, iPhone, and Android — with nothing to keep updated and none of the bundled adware that comes with downloadable free converters.

Where does a Opus file even come from? Usually Discord recordings, WhatsApp and Telegram voice messages, and WebRTC captures. The catch is that Opus is the best lossy codec in use, but it lives inside apps — car stereos, older iPhones and smart speakers won't play it. WAV is the destination when you need uncompressed, edit-ready audio that every DAW and editor accepts. Expect growth, not shrinkage: about 10 MB per minute versus 0.5. That's the price of an uncompressed or lossless container, and it buys you an editing chain that costs nothing further. One honest note on this exact pair: Opus is already lossy, so moving to WAV cannot restore detail the Opus encoder discarded — it hands you an uncompressed container, not better audio, and the value is a loss-free chain from here on.

Frequently Asked Questions

Is it safe to convert Opus to WAV online?

With most online converters your file is uploaded to their servers, so safety depends on a retention policy you'll never read. Here the question doesn't arise: the conversion runs inside your browser and nothing is transmitted. Disconnect from the internet after the page loads and it still works.

How long does an online Opus to WAV conversion take?

Seconds. Expect growth, not shrinkage: about 10 MB per minute versus 0.5. That's the price of an uncompressed or lossless container, and it buys you an editing chain that costs nothing further. With no upload and no download of the result, the only time spent is the conversion itself on your own CPU.

Do I need to install anything?

No — it's a web page. The FFmpeg engine ships to your browser as WebAssembly when the page loads. No software, no browser extension, no command line to learn.

Does it work on my phone?

Yes — Safari on iOS 15.4+ and Chrome on Android both run the conversion fully, so you can convert on whichever device happens to hold the file.

Will the WAV sound different from my Opus?

Don't expect an upgrade: WAV faithfully preserves whatever you give it, including everything Opus already threw away. The value is a loss-free chain from here on, not restoration.
