There is no difference at all between .jpeg and .jpg. Early Windows and DOS limited extensions to three characters, so the format was truncated to .jpg there while Mac and Unix software kept the full .jpeg. Both spellings open in the same programs and you can rename one to the other safely.

## Converting it

A .jpeg file is commonly converted to .jpg, .png, .webp, .pdf or .tiff. It is a binary format, so a text editor will show unreadable characters rather than its contents.
