A JPG file, also known as JPEG, is a popular image file format. It stands for Joint Photographic Experts Group, the name of the group that developed it.
This format is widely used for its efficient compression, which reduces file size while maintaining a reasonable level of image quality. It's particularly favored for photographs and complex images with smooth variations in color and tone. However, this compression can result in loss of quality, especially when the image is edited and saved multiple times.
JPG files are commonly used on the internet, digital cameras, and for photo storage due to their balance of quality and file size.
