What is a JPE File?
A JPE file is basically a JPEG or JPG file, with the same content and everything. A .JPE file is a 24-bit compressed JPEG format, usually used for images with lots of different colors. The JPEG file format uses a lossy compression algorithm, saving some space on your storage drive but compromising the quality of the original image.
Basically, JPE is just an abbreviation for JPG/JPEG and can be converted from one file extension to another simply by renaming the extension.
That said, some digital cameras saved 2 copies of the same image: one as JPE in low resolution, and the other as JPG in a higher resolution, so both could be used by the photographer as needed. However, some applications that do recognize the JPEG format do not recognize the JPE format.
