Your MP3 file
Download MP3Use one complete logical Ogg Opus audio stream, mono or stereo. Chained or multiplexed streams, Vorbis audio, raw Opus packets and Opus in WebM are outside this page. The existing Ogg converters handle Vorbis rather than .opus files. MP3 adds a new lossy encoding and cannot restore detail lost in Opus encoding. Use a sample rate of 8–48 kHz.
How to convert Opus to MP3
- Choose your Opus file. The current file and duration limits appear above.
- Choose Inspect Opus to upload the original and check its audio.
- Review and confirm each required choice, then choose Convert to MP3.
- Preview if your browser supports it, or download the .mp3 file.
Which Opus files can I convert?
This page accepts one complete mono or stereo logical Ogg Opus stream in an .opus file. Chained or multiplexed Ogg, surround channel mappings, Vorbis, raw Opus packets and WebM containers are excluded.
Will MP3 restore the original sound?
No. These inputs already use lossy audio compression. MP3 adds another lossy encoding at 128 kbit/s, so identical sound is not guaranteed.
What happens to metadata and sample precision?
Inspected tags and chapters are omitted after your confirmation. If decoding requires a reduction to signed 16-bit samples, review and confirm that separate choice before converting. Creating MP3 requires a separate choice for new lossy encoding.
Can I use the related audio containers here?
Use the WebM converter for Opus in WebM. The existing Ogg converters are for Vorbis and do not treat .ogg and .opus as interchangeable.
What are the file and duration limits?
The converter shows the current file-size and duration limits before upload. Only mono or stereo audio at 8–48 kHz is supported. A file within those limits can still be rejected for an unsupported container, codec or stream layout.
