Method A to method E are lossy compression. JPEG is a lossy format, Converting an image from other formats( e.g. PNG, BMP ) to JPEG format will cause quality loss. However, compressing an existing JPEG image with method F and G will not change quality, the transformation is lossless, making it easy to reduce image size without losing quality.
Lossless compression only works when no resizing is applied, if you don't wish to lose image quality, please don't resize your images by setting both of the "W" and "H" field to zero.
