Detailed explanation-1: -In lossy compression, the data in a file is removed and not restored to its original form after decompression. Specifically, data is permanently removed, which is why this method is also known as irreversible compression. This data loss is not usually noticeable.

Detailed explanation-2: -By compressing a file, data takes up less space, and files can be sent and received a lot more quickly.

Detailed explanation-3: -Lossy compression can compress data down to significantly less bits than lossless compression can. Data compressed with lossy compression cannot be restored back to its original state. Lossy compression throws away a lot of the original data, but humans can’t even tell anything is missing.

Detailed explanation-4: -How Compression Works. Compression software works by using mathematical equations to scan file data and look for repeating patterns. The software then replaces these repeating patterns with smaller pieces of data, or code, that take up less room.
