Image compression is a technology used to reduce the size of digital images while maintaining visual quality for storage or transmission purposes. This process involves analyzing and reducing redundant data in an image file in order to reduce the amount of space it occupies without significantly affecting the image's appearance to the human eye. Different compression algorithms are used to achieve this, such as lossy and lossless compression methods. Image compression is widely used in various applications, including digital photography, web design, medical imaging, and satellite communications.
