免费在线 JPE 转 G4 转换器

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.

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).
