JPG to JPEG Exact same Format Distinct Extension

Wiki Article

JPEG and JPG are identical image formats. No technical difference between a .jpg photo and a .jpeg photo — both use exactly the same JPEG encoding method and store image data in the identical manner.

The sole distinction is only in the file extension, being a historical artifact from the early days of computing. The JPEG format was created in 1992 by the Joint Photographic Experts Group. When Microsoft introduced early versions of Windows, the system had a restriction: extensions could only be 3 characters.

Causing the 4-character .jpeg suffix to be abbreviated to .jpg for Windows computers. Mac and Unix systems, which never had this three-character restriction, could use the full .jpeg extension from the outset.

While both extensions work identically in nearly all today's programs, certain situations where a platform may specifically require the .jpeg extension. When this happens, renaming the file from .jpg to .jpeg is all that is needed.

No image here data conversion is needed — simply renaming the extension resolves the problem usually.
