What are Opus and WAV files?
Opus (.opus)
Opus is a modern, highly efficient audio codec used by WhatsApp, Discord, Zoom and YouTube. WhatsApp voice messages are Opus audio, which many music players cannot open.
WAV (.wav)
WAV stores uncompressed audio with perfect quality. It is used in recording studios, editing and voice-over work, but files are about 10× bigger than MP3.
Tips for the best WAV results
- For phones and social media, MP4 (H.264 + AAC) is the safest choice for video and MP3 for audio.
- Very large files (over 1 GB) may exceed browser memory on phones; trim them or use a computer.
- 128 kbps is ideal for speech (lectures, waz, voice notes) and 192–320 kbps for music.

Private by design: how this converter works
Unlike typical online converters that upload your file to a remote server, this Opus to WAV converter processes everything on your own device using FFmpeg compiled to WebAssembly — the same engine used by professional video tools. Your file is read into browser memory, converted, and offered back as a download — it is never sent to us.
- No upload wait — conversion starts instantly, even on slow mobile data.
- Private — safe for NID copies, certificates, bank statements and personal photos.
- No limits — no daily quota, no queue and no watermark.
- Offline-ready — once loaded, many tools keep working without internet.
