G4 is a method to compress black and white images without losing quality. It is used for fax machines and as a one of the compression types for the TIFF format. G4 treats a picture as black dots and lines on a white page (less file size will be achieved if there are less black dots and lines).

JPE is an extension used as an optional alternative for JPEG images. It is usually used by digital cameras. For example, some Sony cameras are able to save a high quality JPG image along with the low-res copy in JPE for sending via email.
