Types of Web Graphics

GIF: GIF (Graphics Interchange Format) is the most common graphic type on the web. It can be pronounced with a hard or soft “g.” GIF is limited to 8-bit color information (256 colors) and works best for line art. It allows for transparent and animated graphics.
JPEG: JPEG (Joint Photographic Experts Group) was designed for color-rich images, such as photographs. JPEG compresses graphics with high color depth (24-bit color -- up to 16 million colors) so that they are smaller and download faster. JPEG compression is "lossy" -- some image detail is lost during compression
PNG: PNG (Portable Network Graphic) was also designed for color-rich images, but unlike the JPEG format, PNGs are not lossy. PNGs use vector graphic technology to display images in rich detail regardless of the size of the image.
