Detailed explanation-1: -JPEG (/ˈdʒeɪpɛɡ/ JAY-peg) is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality.
Detailed explanation-2: -JPEG (Joint Photographic Experts Group image) JPEG is actually a data format for compressed photos, rather than a file type. The JFIF (JPEG File Interchange Format) specification describes the format of the files we think of as “JPEG” images.
Detailed explanation-3: -Most compact-style digital cameras have JPEG as their default capture format; some allow you to select between JPEG and other file formats. JPEG is a ‘lossy’ compression format. When you save an image as a JPEG file, a certain amount of picture information is irretrievably discarded.
Detailed explanation-4: -JPEG files All JPEGs are the same universal standard format, whatever their size and quality. If you set your camera to save your shots as JPEGs, the camera processes the image information it has captured and saves a compressed file.
Detailed explanation-5: -The PNG file format is optimized for digital use, making it the most commonly used image format. It also supports more colors than the GIF format – PNG can handle up to 16 million colors, while GIF only supports 256 colors.
