Detailed explanation-1: -There are two methods of compression – lossy and lossless. Lossy reduces file size by permanently removing some of the original data. Lossless reduces file size by removing unnecessary metadata.
Detailed explanation-2: -Lossy compression reduces a file by permanently eliminating certain information, especially redundant information. When the file is uncompressed, some of the original information is not there, although the user may not notice it.
Detailed explanation-3: -Lossy compression is best at creating really small file sizes – ideal for downloads or streaming. File formats that use lossy compression include MP3, MP4 and JPG. Our MP3 Audio Compression page explains more about MP3 compression.
