JPG is the file extension for one of the most popular image formats. According to statistics on critical web technologies, approximately 40 percent of all images on the web are JPGs.
JPG images use a lossy compression method, which reduces their storage size thereby reducing image quality. JPG excels when it comes to its ability to achieve compression up to 10:1 without any noticeable degradation in image quality. This makes JPG images ideal for non-professional casual and web photography.
JPG and JPEG are generally confused as both are the file extensions of a lossy graphics format, however JPEG also refers to the compression method used by said file format, Joint Photographic Experts Group.
Joint Photographic Experts Group, belonging to ISO, is the name of the subcommittee that helped to create the JPEG standard, as well as other still image encoding standards, always under the larger group ISO.
ISO sets the standards for many things, including digital images, in an effort to provide users and consumers with products and services of the highest quality.
It is important to understand that the JPEG compression method can be saved with different file extensions: JPG, JPEG, as the extensions simply tell other programs or applications that they are dealing with an image file that was saved using the compression method JPEG.
Basically, the goal is not to negatively affect the speed and performance of a website that contains images, by using large images that waste resources and take a long time to load in the interface.
In fact, all website owners need to optimize their images in some way to reduce their image file sizes and preserve load times and user experience.
This is where the JPG enters into play, since, as mentioned above, the images undergo compression that makes them more friendly with the resources and loading times of the websites.
