SVG — the SVG format — is completely separate from JPG. JPG encodes pictures as a raster of pixels, SVG encodes illustrations as mathematical definitions of shapes, lines and colors. This means SVG files work at all sizes — from a small icon to a large banner — with no quality loss.
Converting JPG to SVG is a process referred to as raster to vector conversion, and it is very beneficial for icons and clean 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 website applications renders as the image.
Results are excellent 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 quality conversion, Adobe Illustrator's Image Trace feature offers the most control. Load the image in Illustrator, select the graphic, open the Image Trace settings and choose an relevant setting.
