Detailed explanation-1: -Lossless compression is a compression technique that does not lose any data in the compression process. Lossless compression “packs” data into a smaller file size by using a kind of internal shorthand to signify redundant data.
Detailed explanation-2: -With lossless compression the file data is restored and rebuilt in its original form after decompression, enabling the image to take up less space without any discernible loss in picture quality. No data is lost and as the process can be reversed, it’s also known as reversible compression.
Detailed explanation-3: -Lossless compression can reduce file sizes by removing and isolating redundant data. This method can make files smaller without affecting their overall quality. It is also completely reversible.
