Why convert OPUS to WAV?
You received a WhatsApp, Telegram or Discord voice message (.opus/.ogg) and it will not open on your computer, car stereo or editing software. WAV solves the problem.
How to do it, step by step
- Drop your OPUS fileinto the area at the top of the page (or several files at once). On mobile, tap the area and pick the file from your apps.
- Check the output format: WAV is already selected. WAV is a lossless format: there is no quality setting, the sound is reproduced identically. The file will be noticeably larger than a compressed format.
- Start the conversion.The FFmpeg engine loads once (≈ 10 MB), then each file is processed in a few seconds without leaving your device.
- Download your WAV, directly or as a .zip if you converted several files. The name and metadata (title, artist, cover art) are preserved.
The OPUS format (Opus Interactive Audio Codec)
Opus is currently the most efficient audio codec: it delivers the best possible quality at very low bitrates. It is the format of WhatsApp, Telegram and Discord voice messages and of video calls. Excellent, but still poorly recognized by consumer players and car stereos.
- Exceptional quality at low bitrates
- Free format
- The standard for voice on the internet
- Very few devices play it
- Often impossible to open on Windows without extra software
The WAV format (Waveform Audio File Format)
WAV is an uncompressed format: it stores raw audio, exactly like a CD. The quality is perfect but the files are large (about 10 MB per minute at CD quality). It is the reference format for audio editing, music production, transcription and professional software.
- No quality loss
- Read by every audio application
- Ideal for editing and transcription
- Very large files
- No standardized metadata (title, artist)
