How to convert Opus to MP3
WhatsApp voice notes and Discord recordings are often Opus files, which many players and editors don't open. MP3 plays anywhere.
- Drop your Opus file into the box above, or add it from a link.
- MP3 is already selected. Use the settings button next to it to change size, quality or other options.
- Select Convert, then download your MP3 file.
To do this from your own code, call the FileForge API with "output_format": "mp3".
Good to know
- Voice notes sound fine at 96–128 kbps.
- WhatsApp sometimes saves voice notes as .ogg; those convert the same way.
About the formats
.opus
Opus is a modern audio codec used by WhatsApp voice notes, Discord and WebRTC calls. It sounds great at low bitrates but many players and editors don't recognise .opus files.
.mp3
MP3 is the universal audio format: every phone, car stereo, speaker and app plays it. It uses lossy compression, so a 3-minute song is a few megabytes.
