MPEG vs. MPG: What's the Difference?

Edited by Aimie Carlson || By Janet White || Published on December 9, 2023
MPEG refers to a set of standards for audio and video compression and transmission, while MPG is a file extension for MPEG-1 or MPEG-2 audio and video compression.

Key Differences

MPEG (Moving Picture Experts Group) is the name of a working group that develops standards for digital video and audio compression. MPG, on the other hand, is a file extension used for files encoded using the MPEG-1 or MPEG-2 standard.
MPEG sets the framework for audio and video compression and transmission. MPG files are practical implementations of these standards, commonly used for digital video files, especially in older digital video content.
MPEG standards have evolved over time, leading to various versions like MPEG-1, MPEG-2, MPEG-4, and more. MPG, typically associated with MPEG-1 and MPEG-2, represents an older generation of these standards and is less used in the context of newer MPEG formats like MPEG-4.
MPEG standards aim to balance quality and compression efficiency, influencing various digital media formats. MPG files, following the MPEG-1 and MPEG-2 standards, offer a balance between quality and file size, making them suitable for earlier digital video playback and DVD quality.
The term MPEG is a broad reference to a family of standards, not confined to a specific file format. MPG as a file extension specifically refers to a file format following the MPEG-1 or MPEG-2 standards.
