SVG — vector graphics — is fundamentally different from JPG. While JPG stores images as a grid of pixels, SVG stores images as geometric descriptions of paths and colors. Meaning SVG graphics can be displayed at every size — from a tiny icon to a large banner — without any loss of sharpness.
Converting JPG to SVG is a technique known as image vectorization, and it is particularly valuable for illustrations and flat artwork.
Prior to converting JPG to SVG, it is important to understand what happens. JPG files are a raster image — a set check here grid of dots. An SVG is a scalable image — a series of geometric shapes which software uses to draw the artwork.
The conversion works great for uncomplicated graphics with defined shapes and limited colors — icons, logos, symbols and illustrations. It does not work for complex photos with complex gradients.
For best output, Illustrator's Image Trace function offers the most control. Load the image in Illustrator, highlight the image, open the Image Trace settings and pick an suitable option.
