How to convert OPUS to WAV

- Check the target. WAV is preselected. Pick High, Medium or Small quality depending on whether you need a master copy or a small file.
- Download. The conversion engine loads once (32 MB) and then your file is processed locally. The WAV file downloads automatically when it is done.
Why convert OPUS to WAV?
OPUS files are not supported everywhere. Converting to WAV gives you an uncompressed file that editors, DAWs and mastering tools handle natively.

What makes this converter different
- Nothing is uploaded. Other converters send your file to a server, queue it, and keep a copy for hours. Here the work happens in your browser with WebAssembly, so private videos, voice memos and documents never leave your computer.
- No limits, no sign-up, no watermark. There is no server to pay for, so there is no reason to cap file size or count.
- Real ffmpeg quality. Video and audio use the same ffmpeg encoders professionals use (x264, LAME, libvpx, FLAC), not a stripped-down web codec.

Frequently asked questions
Is it safe to convert OPUS to WAV here?
Yes. The conversion runs entirely inside your browser using WebAssembly. Your file is never uploaded to a server, so nothing can leak, be stored or be seen by anyone. You can even disconnect from the internet after the page loads.
How long does OPUS to WAV conversion take?
Audio converts at roughly 20–50× real time, so a 5-minute song takes about 10 seconds after the one-time engine download.
Is there a file size limit?
There is no server-side limit because there is no server. The practical limit is your device memory: browsers can handle files up to about 2 GB. Very large videos work better on a desktop than a phone.
Will the quality drop?
WAV is lossless, so no quality is lost relative to the source. It cannot recover detail that a lossy source already discarded.
Can I convert several OPUS files at once?
Yes. Drop or select as many files as you like; they are converted one after another and each gets its own download button.
