JPG to JPEG Identical Structure Diverse Extension

JPG and JPEG are the same photo formats. No distinction between a .jpg photo and a .jpeg photo — both employ the very same JPEG encoding method and encode pictures in the identical manner.

The only difference is entirely in the extension, being a historical artifact from early computer history. The JPEG format was developed in 1992 by the Joint Photographic Experts Group. The Windows operating system released early versions of Windows, the OS had a limitation: extensions were limited to be 3 characters.

This forced the 4-character .jpeg suffix to be abbreviated to .jpg for Windows users. Mac and Unix systems, not having the extension limitation, used the full .jpeg file extension from the start.

While both file types function the same in virtually all today's programs, some scenarios in check here which a platform requires the .jpeg extension. When this happens, renaming the file from .jpg to .jpeg is all that is needed.

No real conversion of image data is necessary — simply updating the file extension resolves the issue almost always.
