Need help?How to Convert MPEG to Opus Online
- Upload Your MPEG Files — Drag and drop or select one or more MPG or MPEG video files.
- Choose a Quality Preset — Select from Highest, Very High (Recommended), High, Medium, Low, Very Low, or Lowest. This controls the Opus output bitrate.
- Adjust Audio Settings (Optional) — Change the Audio Channel to Original, Mono, or Stereo. Set a specific Sample Rate (Original, 8000 Hz, 12000 Hz, 16000 Hz, 24000 Hz, 44100 Hz, or 48000 Hz).
- Trim (Optional) — Set a start time and duration in seconds or HH:MM:SS.sss to extract audio from a specific segment.
- Convert & Download — Click Convert and download your Opus files.
Why Convert MPEG to Opus?
MPEG video files typically contain MP2 audio — a codec from 1993 that is far less efficient than modern alternatives. Opus is the state-of-the-art audio codec, delivering files 30–50% smaller than MP2 at the same perceived quality. It excels at both speech and music, handles bitrates from 6 kbps to 510 kbps, and is the default audio codec for WebRTC, Discord, and YouTube's internal audio streams. Extracting audio from MPEG as Opus gives you the smallest possible file with the best quality.
MPEG Audio (MP2) vs Opus
| Feature | MP2 (inside MPEG) | Opus (output) |
|---|---|---|
| Era | 1993 | 2012 |
| Compression efficiency | Baseline | 30–50% better |
| Quality at 64 kbps | Poor | Very good |
| Quality at 128 kbps | Acceptable | Excellent |
| Latency | High | Ultra-low (ideal for real-time) |
| Royalty-free | ✅ | ✅ |
| Web browser support | ❌ | Chrome, Firefox, Edge, Opera |
Use Cases
- Web audio — Opus is purpose-built for web delivery. Extract audio from MPEG recordings for embedding in HTML5
<audio>elements. - VoIP / streaming — Opus's ultra-low latency makes it ideal for real-time communication applications.
- Podcast production — Extract interview or broadcast audio from MPEG video and distribute as Opus for modern podcast players.
- Storage optimization — Replace bulky MPEG files with tiny Opus audio files when you only need the sound.
Does this extract audio from the video?
Yes. The converter decodes the audio stream from the MPEG container (typically MP2) and re-encodes it as Opus. The video track is discarded.
Is Opus better than MP3?
Yes. Opus produces better quality at the same bitrate, especially below 128 kbps. It is also royalty-free and has lower latency. The only downside is that very old devices may not support Opus playback.
What Quality Preset should I use?
"Very High" is recommended for music. For speech, "Medium" or "High" is sufficient — Opus is exceptionally efficient at encoding voice even at low bitrates.
Can I extract audio from both .mpg and .mpeg files?
Yes. Both extensions refer to the same MPEG video format. The converter accepts either.
Will Opus files play on my phone?
Android supports Opus natively. iOS supports Opus in Safari 15+ and most third-party apps. For maximum compatibility with older devices, consider MPEG to MP3 instead.
