Six Tools to Convert MPG to MP4 on Windows, Mac & Online

Suppose you have plenty of old videos available in MPG file format on your CDs, DVDs, or computer to make their accessibility flexible & all devices compatible. In that case, you must convert MPG to MP4.

Despite being in the same company's video file format, Motion Picture Experts Group (MPEG), MPG, and MP4 differ in various ways. So, if you think about why you even need to convert MPG to MP4, you must know that MPG has certain limitations that the MP4 file format can easily overcome.


When an MPG file uses the old MPEG-1 and MPEG-2 encoding to store audio, video, and metadata with slightly lossy compression, MP4 uses the advanced MPEG-4 codec to store more multimedia data, including audio, video, images, subtitles, metadata, etc., with maximum file compression and minimum data loss. So, while you know the most helpful reason for MPG to Mp4 file conversion, here are the top 6 MPG to Mp4 converters for Windows, Mac, and Online.


MPG to Mp4


Why to Convert MPG to MP4


Even though both the MPG and Mp4 files are digital media container formats, there are certain advantages of Mp4 over MPG that make your digital media streaming experience more flexible and comfortable.


  • Mp4 handles more digital media data than MPG and cannot store subtitles, images, etc.


  • MP4 is compatible with most devices, media players, OSs, and platforms and supports seamless media streaming on the internet. However, MPG is mostly created to deal with digital content on CDs, DVDs, Televisions, etc., and it is commonly compatible with the built-in media player of Windows and Mac, VLC Media Player, and other limited media players.


  • Most digital streaming platforms support MP4 over MPG because of its small file and more compressed file size with lossless compression support.


  • Despite offering maximum compression, MP4 doesn't compromise content quality and supports HD, 4K, and higher resolution in very small file sizes. Despite using lossy compression, MPG can't reduce file size and also can't support HD or high-quality video.


  • MPG consumes more device storage than MP4 to store any digital media content.


  • MPG supports only two old codecs, such as MPEG-1 and MPEG-2, but Mp4 offers multiple advanced codec support like H.264 or AVI, H.265 or HEVC, Cinepak, Dirac, etc
