Detailed explanation-1: -Lossless compression restores and rebuilds file data in its original form after the file is decompressed. For example, when a picture’s file size is compressed, its quality remains the same. The file can be decompressed to its original quality without any loss of data.
Detailed explanation-2: -Lossless data compression algorithms (such as PNG) are reversible (there is no loss in quality); you can reconstruct the original data.
Detailed explanation-3: -Lossless algorithms. 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-4: -Lossless compression is a form of data compression that reduce file sizes without sacrificing any significant information in the process-meaning it will not diminish the quality of your photos. No details are lost along the way, hence the name.
Detailed explanation-5: -Lossy compression techniques involve some loss of information, and data that have been compressed using lossy techniques generally cannot be recovered or reconstructed exactly.
