Image Compression: Image compression is the process of reducing the file size of digital images without significantly affecting their visual quality. This technique is used to optimize website performance, improve page load times, and decrease bandwidth usage, resulting in a better user experience. There are two main types of image compression: lossless and lossy. Lossless compression maintains the original image quality, while lossy compression sacrifices some quality for greater file size reduction. Examples of image compression formats include JPEG, GIF, and PNG.
