How to convert MPG to MP3
- Add your .MPG file - drop it in the box above or click to browse.
- Convert it to .MP3 in a few seconds.
- Download your new .MP3 file.
What to expect
- MPG audio is usually MP2 or AC-3, not MP3 - a re-encode always happens, adding one lossy step on top of an already-lossy source; quality loss is minor at 192 kbps but not zero.
- The video track is completely discarded; the
.mp3output is audio only - convert to MP4 if you need to keep both audio and video. - Some
.mpgfiles are video-only elementary streams with no audio track at all; if the output is silent or missing, that is why.
Frequently asked questions
Does converting MPG to MP3 reduce audio quality?
Yes, slightly. MPG audio (MP2 or AC-3) must be decoded and re-encoded to MP3, adding one generation of lossy compression. The difference is barely audible at 192 kbps or higher.
Can I extract just a clip instead of the whole file?
With ffmpeg, add
-ss HH:MM:SS -to HH:MM:SS before the input to extract a specific time range rather than converting the whole file.Why is my converted MP3 silent or empty?
Some
.mpg files are video-only streams with no embedded audio track; if the source has no audio, there is nothing to extract.How much smaller will the MP3 be than the MPG?
Much smaller - a 1 GB MPG can shrink to just a few MB as MP3 because the large video stream is dropped entirely.
