How to convert Opus to MP3
Add one .opus file, choose 128, 192, 256 or 320 kbps, then download the MP3. The default is 128 kbps. This online Opus to MP3 tool runs the conversion on your device, so the file is not uploaded.
Why convert an Opus file to MP3
Opus is common for voice notes and calls from apps such as WhatsApp, Telegram and Discord. Converting to MP3 helps when a player, phone or editing tool does not open .opus files directly.
Choose a bitrate for your MP3
MP3 uses lossy compression. A lower bitrate may make a smaller listening copy; a higher bitrate can retain more detail. Output size and sound depend on the source Opus stream as well as the chosen bitrate.
Need a transcript instead of an MP3?
You can send your original Opus file to audio transcription without converting it here first. Transcription is separate from this free local converter: it uploads prepared audio and requires an account. Speaker labels are available when selected. Eligible personal accounts can receive 30 free minutes after card verification.

Frequently asked questions
Is this Opus to MP3 converter free?
Yes. Converting one Opus file to MP3 in your browser is free and needs no account. Transcription is a separate service with its own account and minute pricing.
Does converting Opus to MP3 upload my file?
No. The converter processes the Opus file in your browser and downloads the MP3 to your device. Choosing transcription separately uploads prepared audio.
Why would I convert Opus to MP3?
Opus voice notes and clips from apps such as WhatsApp, Telegram or Discord often need converting to MP3 for a player or editor that does not open .opus directly.
Which MP3 bitrate can I choose?
Choose 128, 192, 256 or 320 kbps; 128 kbps is selected by default. A higher bitrate can retain more detail but often makes a larger MP3.
Will every Opus file convert and play on every device?
Conversion depends on the Opus stream your browser can decode and your device. Playback of the resulting MP3 depends on your player.
