# Convert Opus to MP3

Convert Opus to MP3 right in your browser — free, private, nothing is uploaded. One-click re-encode for compatibility.

Opus delivers the best quality per bit of any mainstream codec — it beats MP3, Vorbis and AAC at almost every bitrate and powers WhatsApp voice notes, Discord and WebRTC. Device support, though, is still patchy outside browsers and messengers.

MP3 is the most widely supported audio format there is — a lossy codec that shrinks audio to a fraction of its uncompressed size and plays on virtually anything with a speaker.

Converting Opus to MP3 is a compatibility move: both formats are lossy, so the goal isn't quality — it's producing a file that fits sharing, podcasts and everyday listening. Expect the sound to stay essentially the same, with a small second round of encoding loss.
