SVG — the SVG format — is completely separate from JPG. JPG encodes pictures as a grid of pixels, SVG encodes illustrations as mathematical descriptions of shapes, lines and colors. This means SVG images work at all sizes — from a small icon to a massive print — with no quality loss.
Changing JPG to SVG is a process called raster to vector conversion, and it is very beneficial for illustrations and clean graphics.
Prior to converting JPG to SVG, it is important to realize what happens. JPG files are a raster image — a fixed grid of image pixels. An SVG is a vector image — a set of mathematical instructions that applications renders as the image.
This works extremely well for uncomplicated graphics with defined shapes and limited colors — icons, logos, symbols and line art. It works less well for detailed photographs with fine detail.
For professional results, Illustrator's Image Trace feature gives the most flexibility. Load the image in Illustrator, click the graphic, open the Image Trace dialog and select an appropriate preset.
