JPG and JPEG are identical file formats. No distinction between a .jpg photo and a .jpeg photo — both employ the very same JPEG encoding method and encode photos in the identical manner.
The only difference is entirely in the file extension, which is a relic from early computing. JPEG was introduced in 1992 by the Joint Photographic Experts Group. Early Windows launched Windows in the early era, the operating system enforced a restriction: file extensions could here only be no more than 3 characters.
Causing the four-character .jpeg suffix to be abbreviated to .jpg for PC users. Mac and Unix systems, not having the three-character restriction, continued using the complete .jpeg extension from the outset.
Although both extensions perform equally in almost every modern software, certain cases when a system may specifically require the .jpeg file type. In these cases, converting from .jpg to .jpeg is sufficient.
No image data conversion is necessary — just updating the file extension resolves the problem almost always.
