Generation loss — quality may degrade
MPEG uses lossy compression, and so does OPUS. Converting means decoding and re-encoding — each cycle can permanently degrade quality. Convert from the original source file whenever possible.
What compression artifacts to expect
OPUS lossy compression can produce minimal artifacts even at low bitrates. At the high quality settings CocoConvert uses by default, these are usually invisible to the eye. Lower quality settings trade visual fidelity for smaller file sizes.

The conversion engine behind CocoConvert uses FFmpeg, Sharp, and qpdf — the same open-source libraries trusted by Netflix, YouTube, and enterprise platforms. Pro users can batch convert up to 100 files at once.
How to Convert MPEG to OPUS
- 1
Add your MPEG file
Drag and drop your .mpeg file into the converter, or tap "Browse" to pick it from your device. Multiple files are supported for batch processing.
- 2
Pick OPUS output
Select .opus as the target format. CocoConvert automatically applies the best quality settings for this conversion.
- 3
Start conversion
Hit the Convert button. The video engine processes your file server-side — no CPU drain on your device.
- 4
Save your file
Once done, download your .opus file. For batch jobs, download all at once as a zip.
What Happens When You Convert MPEG to OPUS
The audio track is extracted from your MPEG video file and saved as OPUS. The video frames are discarded.
Your MPEG file is opened and the container is parsed to identify audio and video streams
The audio stream is extracted — if it's already in the target codec, it's copied directly (no quality loss)
If transcoding is needed, the audio is decoded and re-encoded as OPUS
Video frames, subtitles, and chapter markers are discarded
The OPUS file is saved with preserved metadata (title, artist, etc.) where possible
