Free online OPUS to WAVE converter

Brief explanation of the source format

OPUS is a modern, highly efficient audio compression format designed for speech and music alike. It is widely used in VoIP, online meetings, streaming, gaming voice chat, and web audio because it delivers very good quality at relatively low bitrates. OPUS files are commonly found as .opus audio files, often inside containers such as Ogg.

Brief explanation of the target format

WAV is a uncompressed or lightly structured audio container most often used with PCM audio. It is a long-standing standard for editing, mastering, archiving, and compatibility with audio software and hardware. The main advantages of WAV are wide support, simple decoding, and lossless storage of the decoded audio. The tradeoff is much larger file size than OPUS.

How to perform the conversion

The most reliable way to convert OPUS to WAV is with FFmpeg, which is free, widely available, and preserves audio quality as well as possible during decoding.

1. Install FFmpeg on your computer if it is not already available.
2. Open a terminal or command prompt in the folder containing the OPUS file.
3. Run a command such as ffmpeg -i input.opus output.wav.
4. Wait for the conversion to finish, then open output.wav in your audio editor or player.

If your OPUS file has a different extension or is inside another container, FFmpeg can still usually detect it correctly as long as the file is valid. For batch conversion, you can repeat the command for each file or use a script.

If you prefer a desktop application with a graphical interface, Audacity can import OPUS and export WAV. Typical steps are File → Import → Audio, select the OPUS file, then File → Export → Export as WAV.

You can also convert the file on 101convert.com for free, without installing any software.

Notes on quality, compatibility, or limitations

OPUS is lossy, so converting it to WAV does not restore any audio detail that was removed during OPUS encoding. The WAV file will contain the decoded audio in a larger, uncompressed form, which is ideal for editing or compatibility but not for saving space.

Because WAV is usually PCM-based, the output may be much larger than the source file. Also, if the OPUS file uses a nonstandard sample rate or channel layout, FFmpeg and Audacity will still typically handle it correctly, but some older audio tools may have trouble with unusual WAV variants. For maximum compatibility, standard PCM WAV is the safest choice.
