What is JPEG? #

What is JPG? #
There is no real difference between JPEG and JPG. JPG is the abbreviation of JPEG, because the earlier Windows versions could only handle file extensions with a maximum of 3 letters. Therefore, even today JPEG images are often saved with the extension .jpg in order not to cause problems with older systems.
So the only difference is the spelling.

The maximum size that is supported is 65,535×65,535 pixels. When saving, the size of the image is reduced by about 50-75%. This means that the file size is smaller than the original size, but at the same time it also results in faster loading time on web pages. However, the file format is not suitable for images with sharp edges, as the colors in the image blend together. (The PNG format is better suited for this, as it stores the individual pixels).
