M4A vs MP3

M4A (MPEG 4 Audio)

M4A is a file extension for an audio file encoded with advanced audio coding (AAC) which is a lossy compression. It is very similar to MP4, but it does not contain videos like MP4. Compare with MP3 files, M4A files are smaller in size and better in quality.

MP3 (MPEG-1 Audio Layer III or MPEG-2 Audio Layer III)

MP3 is a coding format for digital audio. It is used to compress a sound sequence into a very small file to enable digital storage and transmission. MP3 is the most common audio format on websites and multimedia players due to its small size, acceptable quality, as well as easy to store and share.
