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.
