When we listen to downloaded music, we often hear our music in a “compressed” form like an MP3. These are files that have been adjusted to take up a minimal amount of storage space on your phone or computer. They compact files are “lossy” which result in tracks that might be missing some of the high-end details present in the original records. Lossless audio still compresses the files but utilizes a specific algorithm that can minimize size without sacrificing detail. Lossless file types include FLAC, AIFF, and ALAC (Apple Lossless Audio Codec). This is a fairly simple explanation, and there is certainly more to learn but, at the end of the day, lossless audio is more desirable than the alternative.
