MP3 vs MP4

MP3, short for MPEG-1 Audio Layer 3, is an audio coding format that adopts lossy data compression. As MP3 files are so good at storing audio, they have become the de facto standard for music software, digital audio players, and music streaming sites, and now are widely used for audio streaming or storage. No matter which operating system or device you own, you can be confident MP3 files will work right out of the box without a hitch.

MP4 is a digital multimedia format that deals with audio, video, image and text, which differs significantly from MP3. As such, MP4 files do not have a native way of handling the coding of the file. To determine how the coding and compression will be handled, they rely on specific codecs.

As a matter of fact, when to use MP3 or MP4 depends on what you are using them for. If you prefer listening to music on MP3 player and smaller file size, use MP3.
