SVG, or Scalable Vector Graphics, is among the most interesting, and potentially useful image formats today. Unlike the other formats here, SVG is a XML mark-up language for vector graphics. Vector graphics, based on Wikipedia, is the utilization of geometrical primitives such as points, lines, curves, and polygons to represent images in computer graphics. Rather than having all the information for each and every pixel in an image, as all the prior image formats do, SVG defines things over these geometrical primitives. This implies, when you increase the size of an SVG image, it always stays sharp, and never becomes pixilated. This is often quite useful for logos and other simple graphics, enabling many different sizes of the identical image to be used with no loss in quality. Also, SVG images typically have very small file sizes. As noticed in the picture, SVG graphics aren't photo-realistic. They also require different skills and, generally, different programs to produce them.
For web design, svg files will be the dream for quality of images; unfortunately, Web browser 6 and Safari both require plug-ins to see SVG files. Still, SVG images bring a lossless image utilized as the archive version, then converted into JPEG or PNG files to be used on the web.
