Lossless compression algorithms reduce the size of files without losing any information in the file, which means that we can reconstruct the original data from the compressed file. WebJPEG compression reduces file size by changing the color values and blocking together groups of pixels with a more uniform color, so that it doesn’t have to store as many different ones. While this does decrease the file size, it also alters the true image by changing the colors. Are iPhone photos JPEG images? how do i change the type size on pc
