COMPILER DESIGN

Detailed explanation-1: -If you need to reduce the size of your files significantly to save storage space online or on your computer, or you need to boost user experience (UX) or SEO on your photography website, lossy is probably your best option. If you need to maintain the highest possible standards of quality, lossless might be your answer.

Detailed explanation-2: -Although lossless compression is required in many applications, compression ratios obtained with lossless techniques are significantly lower than those possible with lossy compression. Typically, depending on the image, lossless compression ratios range from about 1.5:1 to 3:1.

Detailed explanation-3: -The maximum compression ratio is 90 percent. The maximum compression of any sequence of bytes occurs by replacing each group of 15 bytes with a single 12-bit symbol number, yielding a compressed image that is ten percent of the size of the original image.

Detailed explanation-4: -Typically, depending on the image, lossless compression ratios range from about 1.5:1 to 3:1. On the other hand, state-of-the-art lossy compression techniques give compression rations in excess of 20:1 with virtually no loss in visual fidelity.
