Opus to MP3 Converter
Convert Opus voice notes and audio to universal MP3 in your browser.
Opus is the codec behind voice messages in apps like WhatsApp and Telegram, and it's brilliant for low-bitrate speech. But many players and editors won't open .opus files directly.
Converting to MP3 lets you save, share, or edit those voice notes on any device. Everything is processed locally, so private messages stay private.
