How to Convert MPEG to MP3
Upload
Drag and drop your MPEG video file into the converter above, or click Choose Video File to browse your device.
Extract
Click Convert to MP3. Our server extracts the audio track from your MPEG file and encodes it as MP3. Takes 15 seconds to 1 minute.
Download
Click Download MP3 to save the extracted audio. That's it — no registration, no email required.
Extract Audio from MPEG on Any Device
On Windows 10/11
Windows can play MPEG files through Media Player, but there is no built-in way to extract the audio track as a standalone MP3 file. You would need to install FFmpeg or a dedicated video editor. Convertio.com lets you extract audio from MPEG instantly in your browser — upload the .mpg or .mpeg file, get an MP3 back in seconds.
On Mac
macOS does not natively support MPEG-1 and MPEG-2 video playback without additional codecs. QuickTime cannot open most .mpg files. VLC can play them, but offers no simple audio extraction feature. Our online converter handles MPEG files directly and produces a standard MP3 compatible with every Apple device.
On iPhone / iPad
iOS has no native support for the MPEG format. Third-party apps that handle .mpg files are rare and often require in-app purchases. Open our converter in Safari, upload your MPEG video, and download the extracted MP3 — no app installation needed.
On Android
While some Android devices can play MPEG files through VLC, there is no built-in audio extraction tool. Our web-based converter works in Chrome for Android — upload your .mpg or .mpeg file and download the MP3 directly to your phone's Downloads folder.
What is MPEG?
MPEG (Moving Picture Experts Group) is a family of video and audio compression standards developed since the early 1990s. Files with the .mpg or .mpeg extension typically use the MPEG-1 or MPEG-2 standard — the same technology behind Video CDs, DVDs, and digital television broadcasts.
The audio track inside MPEG files is usually encoded as MPEG-1 Audio Layer II (MP2) at 192–384 kbps, or occasionally as MPEG-1 Audio Layer III (MP3). MPEG-2 files from DVDs often contain AC-3 (Dolby Digital) audio. When you convert MPEG to MP3, the video data is discarded and the audio is re-encoded into the universally compatible MP3 format.
What is MP3?
MP3 (MPEG-1 Audio Layer III) is the world's most widely supported audio format. Standardized in 1993 as part of the MPEG-1 specification, MP3 uses perceptual coding to reduce audio file sizes by 80–90% compared to uncompressed CD audio while maintaining good listening quality.
MP3 plays on every device with audio capability: smartphones, computers, car stereos, Bluetooth speakers, smart watches, and portable media players. At 192 kbps, MP3 delivers quality that is transparent — indistinguishable from the source — for the vast majority of listeners and content types.
MPEG vs MP3: Quick Comparison
| Feature | MPEG (.mpg/.mpeg) | MP3 |
|---|---|---|
| Type | Video + audio container | Audio only |
| Standard | MPEG-1 / MPEG-2 | MPEG-1 Audio Layer III |
| Audio codec | MP2, MP3, or AC-3 | MPEG-1 Layer III |
| Video codec | MPEG-1 / MPEG-2 Video | None |
| Typical file size (3 min) | 20–80 MB (with video) | 3–5 MB (audio only) |
| Compatibility | Legacy players, DVD software | Universal (all devices) |
| Best for | DVD content, archived video | Music, podcasts, audio-only |
Understanding Audio Extraction Quality
When you convert MPEG to MP3, the video track is discarded entirely — only the audio is processed. MPEG-1 files typically carry MP2 audio at 192–224 kbps, while MPEG-2 files from DVDs often contain AC-3 (Dolby Digital) at 192–448 kbps. Converting either to MP3 involves decoding the source audio and re-encoding it with the LAME MP3 encoder.
Since both MP2 and MP3 are perceptual audio codecs from the same MPEG family, the re-encoding process is straightforward. MP3 is actually the successor to MP2, offering improved compression efficiency at the same bitrate. At 192 kbps VBR, the output MP3 provides transparent quality for most content.
The resulting MP3 file is typically 85–95% smaller than the original MPEG video because all video data is removed. A 60 MB MPEG video file may produce an MP3 of just 3–5 MB, depending on the audio duration and selected bitrate.
Why Extract Audio from MPEG Video?
Digitize DVD audio
MPEG-2 is the standard format for DVD video. Extract the audio soundtrack, commentary track, or music from ripped DVD files and save as MP3 for portable listening on any device.
Archive broadcast recordings
TV tuner cards and DVR devices often save recordings in MPEG-2 format. Extract the audio from news segments, interviews, or radio simulcasts for easy archival and playback.
Recover legacy video audio
MPEG-1 was the dominant video format in the late 1990s and early 2000s. If you have old .mpg files from that era, extracting the audio as MP3 preserves the content in a modern, universally playable format.
Reduce storage space
MPEG video files are large compared to audio-only files. If you only need the audio — a speech, music, or sound effects — extracting it as MP3 reduces the file size by 90% or more.
