Detailed explanation-1: -Lossy compression is typically used when a file can afford to lose some data, and/or if storage space needs to be drastically ‘freed up’. Here, an algorithm scans image files and reduces their size by discarding information considered less important or undetectable to the human eye.
Detailed explanation-2: -The JPEG image file, commonly used for photographs and other complex still images on the web with no transparency, is generally compressed using lossy compression.
Detailed explanation-3: -Lossy compression is designed to be used AFTER a video file is completed and isn’t being worked on anymore. Lossy compression is meant to be used to “lock” your video into place. Lossy compression makes video files smaller by reducing the quality of the picture. Once this happens, there is no going back.
