Explanation:
Detailed explanation-1: -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.
Detailed explanation-2: -Lossless compression (like PNG) is reversible (no loss in quality); you can reconstruct the original data. It works by removing redundant data. Lossy compression (like JPG) is not fully reversible; you can only reconstruct an approximation of the original data.
