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.

Detailed explanation-2: -Unlike lossy compression, lossless image compression won’t reduce image quality. That’s because lossless compression only removes additional, non-essential data automatically added by the device used to take the photo. The trade-off is that you won’t see a significant reduction in image file size.

Detailed explanation-3: -Both lossy and lossless compression techniques will result in some information being lost from the original file. Neither lossy nor lossless compression can actually reduce the number of bits needed to represent a file. Lossless compression is only used in situations where lossy compression techniques can’t be used.

Detailed explanation-4: -Lossy compression reduces bits by removing unnecessary or less important information. Typically, a device that performs data compression is referred to as an encoder, and one that performs the reversal of the process (decompression) as a decoder.
