Part 1 MP3 vs. MP4

Before we get to the topic of converting MP3 to MP4, we want to tell you some information about these two file formats, including what MP3/MP4 is and the main differences between them.

MP3 and MP4 sound familiar, and some people may naturally think that MP4 might be the next level for MP3. However that's not so, they are quite different.

MP3 is short for MPEG (Moving Pictures Experts Group) Layer 3, and it is an audio coding format that adopts lossy data compression. MP3 is widely used for audio storage.

MP4, the acronym for MPEG-4 Part 14, is a digital multimedia container format that is widely used for both audio and video storage. Besides that, it handles other data such as text (subtitles) and images as well.
