Image compression reduces the file size of an image. This is particularly important when

by overexposure, underexposure, blurring, weak contrast, image noise, etc.) in order to
create a "better" image.

JPEG standard method for image compression. JPEG is the most common lossy image format
for photos on the Internet. Loss in image quality is barely noticeable at compression rates
lying between 60 and 99 percent.

same image is displayed on the monitor.
