These two formats are identical file formats. No distinction between a .jpg photo and a .jpeg photo — both employ the very same JPEG encoding method and save photos in the identical manner.
The only difference is entirely in the extension, which is a historical artifact from early computing. JPEG was introduced in 1992 by the Joint Photographic Experts Group. The Windows operating system launched Windows in the early era, the operating system enforced a constraint: file extensions could only be no more than 3 characters.
Which forced the four-character .jpeg suffix to be reduced to .jpg for PC users. Mac and Unix systems, which never had the character limit, could use the longer .jpeg extension from the outset.
Although both extensions perform equally in almost every modern software, certain situations 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.
