Part 1. What is an MPG file?

MPG is an audiovisual format created by Moving Picture Experts Group (MPEG) in 1991. It compresses CD audio and VHS-quality raw video without much quality loss. Generally, MPEG is used on video CDs, Digital Audio Broadcasting (DAB), and satellite TV. It uses MPEG-/H.261 or MPEG-2/H.262 lossy compression.

By default, MPG is supported on both Mac and Windows systems. So, use the inbuilt media players like Windows Media Player, Movies & TV App, and QuickTime Player to open MPG without any errors. However, iPhone only supports videos with the MPEG-4 codec. Therefore, this rules out MPG, which uses MPEG-1 and MPEG-2. And yes, the same case applies to Android.

Part 4. FAQs about the MPG file

1. Is MPG the same as MPEG?

Basically, there's no difference between MPG and MPEG. However, the earlier version of Windows systems used to read 3-letter filename extensions. So, MPG filename extension was developed out of this. Just think of it as JPG and JPEG, which can be used interchangeably.

2. What are the differences between AVI and MPEG?

The difference between MPG and AVI is like day and night. First, AVI is an uncompressed file format, meaning it takes up lots of storage space. On the other side, MPG is compressed using MPEG-1 or MPEG-2 algorithms, making it smaller. But note that uncompressed videos offer higher picture quality.

3. MPG vs. MP4: Which is Better?

While MPG uses MPEG-1 and MPEG-2 codecs, MP4 is compressed using MPEG-4, the modern compression method. Now this means MP4 is more universally accepted than MPG. But when it comes to the file size and video quality, these formats are almost proportionate to each other. So, MP4 wins!
