Frequently Asked Questions
What is Opus?▼
Opus is a modern, open audio codec designed for the internet age — outstanding quality at low bitrates, with very low delay. It powers Discord, WhatsApp voice messages, and many streaming apps.
When should I choose Opus over MP3?▼
For voice, streaming, and web apps: Opus sounds clearly better than MP3 below 128 kbps. For maximum device compatibility with music, MP3 or AAC is still safer.
Why convert Opus to MP3?▼
Many players, cars, and editors do not support Opus yet. Converting WhatsApp voice notes or game audio to MP3 makes them playable everywhere.
Does Opus support music as well as speech?▼
Yes — Opus handles both superbly and even switches modes automatically. At 160 kbps it rivals much larger MP3 files for music.
Will converting Opus files upload my voice messages?▼
No. Everything converts locally in your browser — private voice messages stay on your device.
