JPEG - is short for Joint Photographic Expert Group. It is often used in compressing images for web publishing purposes. It is a lossy compression technique commonly used in color images. Although it can reduce file size of images, it will lose some details during compression.
GIF - is short for Graphics Interchange Format.
It is a bitmap (an image file format used to store digital images-pixels) file format use in the World Wide Web. It is commonly used for small animations and icons.
PNG - stands for Portable Network Graphic. PNG is better than GIF due to its compatibility of supporting millions of different color.
The term 'lossy' means that the file of images will lose its details.
