All files encoded in an MPEG-4 standard are associated with the extension ".mp4".

Q02: What is MP3 format?

A: MP3 format, short for MPEG-1 Audio Layer 3, a revolutionary digital audio format, is developed by Fraunhofer-Gesellschaft and Thompson Multimedia in the late 1980s and brought to the mainstream through the Internet in 1997. It is a common audio format for consumer audio storage, as well as a standard encoding for the transfer and playback of music on digital audio players.

Q03: Why do I need to convert MP4 to MP3?

A: People convert MP4 files to MP3 format for various purpose, however, most of them convert MP4 for the two common ones, first they want to extract audio stream from the MP4 video files and save as MP3 format; second their portable devices do not recognize MP4 format at all, but these devices are capable of playing MP3 files without any compatible issues.

Q04: When I am converting MP4 files to MP3 format, does it lose sound quality?

A: This is a good question, but unfortunately, the short answer is YES.
