Detailed explanation-1: -Lossy reduces file size by permanently removing some of the original data. Lossless reduces file size by removing unnecessary metadata.
Detailed explanation-2: -Lossy compression can help you speed up your site, particularly if you have image-heavy content. You can use this compression type on various file formats, including Joint Photographic Experts Group (JPEG) and Graphics Interchange Format (GIF). You can also apply lossy compression to video and audio files.
Detailed explanation-3: -Lossy compression reduces an image file size by permanently removing less critical information, particularly redundant data. Lossy compression can significantly reduce file size, but it can also reduce image quality to the point of distortion, especially if the image is overly compressed.
Detailed explanation-4: -Lossy compression reduces bits by removing unnecessary or less important information. Typically, a device that performs data compression is referred to as an encoder, and one that performs the reversal of the process (decompression) as a decoder.
