JPEG files open automatically on popular web browsers such as Chrome, Microsoft applications such as Microsoft Photos, and Mac OS applications such as Apple Preview. If you experience problems opening a JPEG file, then it is most likely due to the inability of the browser or application to know that the JPEG and JPG file extensions are synonymous.
