These two formats can be confusing to some people because they do not know which they should use. They look the same when you look at their names. In fact, their similarity is so close that they have been used interchangeably during the past.
In this article, we are going to discuss JPG vs JPEG. We will define each of these formats before we give you the similarities between the two to help you decide which format you should use for your needs whether for a website or for online projects. So if you want to know more, keep on reading!

Actually, there is no difference between JPEG and JPG aside from the difference in the character number used in their names. JPG existed because earlier Windows versions required 3-letter filename extensions. Thus, the .jpeg extension was shortened and became .jpg. While DOS and Windows had this filename limitation, UNIX systems did not so MAC and UNIX users continued using the .jpeg filename extension.
But as technology evolved, Windows did too and now accepts more characters for the file extensions. However, the .jpg extension has already been used by many people as well as programs. Thus, making .jpg still the most popular extension. Programs for photo editing such as Gimp and Adobe Photoshop save their JPEG files with a .jpg extension by default on both Mac and Windows systems. But, you can choose either a .jpg or a .jpeg extension and your file will still work.
JPEG is short for Joint Photographic Experts Group which is a compression format for bitmap that is mostly used for lossy compressions. The compression ratio ranges from 10:1-20:1 which you can adjust to determine your balance between quality and storage size. This extension is mostly used by devices for photo sharing and digital cameras.
While the .jpeg format has great colors and is an excellent format for photographs, you need to know that there will be a slight quality loss because of the compression. Plus, re-saving and editing will degrade your image’s quality though the effect is negligible. One method you can use to minimize this quality loss is by working with RAW JPEGs. Decide the things you will be editing and edit once only before saving the final edited version. Do not re-save multiple times.
Now that we have defined what .jpg and .jpeg files are and you have known that they are really not that different, let us take a look at their similarities in this section.
Since .jpg and .jpeg are actually the same, they also use the same compression method, lossy compression, which makes sense. Lossy compression produces images with reduced quality while decreasing their file size too.
Moreover, this only means that regardless of the filename extension you will use (whether .jpg or .jpeg), the size of your image will become smaller compared to the original size. This allows your images to load and upload faster onto your websites for easy viewing of your visitors.
You can create computer images as vector or raster images. Since JPGs are raster files, so are JPEGs. Raster images are image bitmaps. Bitmaps are grids of separate pixels that create one image when combined. In simple words, a raster image is composed of many tiny pixels with different colors that are coded according to their shade or hue.
Since JPG and JPEG are both raster images, they are used in digital photography because digital photographs use extensive seamless color gradations that come out best when saved as JPG or JPEG images. Meaning, the visitors of your site will always be presented with beautiful photographs if you upload them as JPG or JPEG on your website.
