When you convert a song in an uncompressed format to certain compressed formats, some data might be lost in the process. These compressed formats ensure a much smaller file size, which enables you to store more songs. But the sound quality might be as good as the original.

Both MP3 and AAC are lossy and compressed. So MP3 has small file size, but far from the best sound quality. It is convenient for storing music on iPods and smartphones. AAC is intended to act as the effective successor of MP3 and it sounds better. It is often used for Apple music streaming, YouTube streaming, and iTunes download.
