QUICK ANSWER
Is it possible to convert MPG to MP4?
Yes - MPG converts to MP4.

You can do it right here with our free converter - no sign-up, and your file is deleted right after.

The fastest free route is HandBrake - open your .mpg file, choose an MP4 preset, and click Start Encode. Conversion is a full re-encode, so there is minor quality loss, but file size typically drops 60-80% because H.264 is far more efficient than MPEG-2.

Why convert MPG to MP4?

MPG files use older MPEG-1 or MPEG-2 compression, which takes 3-5× more storage than .MP4 at equivalent quality. Many phones, tablets, and websites no longer play .mpg files without extra codecs. Converting to MP4 cuts file size dramatically and ensures playback on virtually any modern device or platform.

About these formats

Quality & what to watch

  • Conversion is a full re-encode - MPEG-2 video must be decoded and compressed again to H.264, introducing slight quality loss; avoid converting the same file multiple times.
  • File size typically drops 60-80% - a 1 GB DVD-quality .mpg often becomes 200-400 MB at the same perceived quality.
  • Audio is also re-encoded - .mpg files often carry MP2 or AC-3 audio, which becomes AAC inside the .mp4 container.

Frequently asked questions

Will I lose quality converting MPG to MP4?
Yes, slightly - re-encoding every frame introduces minor loss, but at HandBrake's defaults or ffmpeg -crf 23 the difference is invisible to most viewers.
Can I convert MPG to MP4 with no quality loss at all?
No - MPEG-2 video is not natively supported inside the MP4 container, so a re-encode to H.264 or H.265 is required; for archival purposes, keep the original .mpg.
How long does conversion take?
A 1-hour DVD-quality .mpg converts in roughly 5-20 minutes on a modern CPU with HandBrake; using hardware encoding such as h264_nvenc on Nvidia can cut that to under 2 minutes.
Does converting to MP4 improve the video quality?
No - conversion cannot add detail that was not in the original file; the best result is near-identical quality at a much smaller file size.
