JPGVSJPG
Is there a difference? Only one letter. Learn why both exist and which one you should use.
The Verdict
**They are exactly the same thing.** There is zero technical difference. OLD Windows systems (DOS) only allowed 3-letter extensions, so they shortened JPEG to JPG. Mac/Linux used JPEG. Today, use .jpg because it is shorter.
