About this opus to wav converter
Opus is the codec behind WhatsApp, Telegram and Discord voice messages: tiny files tuned for speech, but many players and editors cannot open them. WAV is uncompressed PCM audio: large files, no quality loss, and accepted by every editor and DAW. The conversion runs in your browser with ffmpeg compiled to WebAssembly, so the file never leaves your device and there is no size limit beyond your memory. WAV is lossless, so the result sounds exactly like the Opus, no better: quality lost when the Opus was made cannot come back. Use WAV when an editor or device needs it.
