Scalable Vector Graphics — Scalable Vector Graphics — is essentially distinct from JPG. Whereas JPG saves photos as a raster of pixels, SVG encodes illustrations as mathematical definitions of shapes, lines and colors.

Converting JPG to SVG is a process referred to as raster to vector conversion, and it is especially useful for icons and simple graphics.
Before converting JPG to SVG, it is necessary to realize how the process works. A JPG is a raster image — a set grid of dots. An SVG is a vector image — a set of mathematical instructions that applications renders as the image.

For professional results, Illustrator's Image Trace feature gives the most control. Load the image in Illustrator, click the graphic, open the Image Trace dialog and select an relevant setting.
