Scalable Vector Graphics — the SVG format — is completely separate from JPG. JPG encodes pictures as a raster of pixels, SVG encodes illustrations as mathematical descriptions of paths and colors. Meaning SVG images scale to any size — from a 16x16 pixel favicon to a billboard — without pixelation.
Transforming JPG to SVG is a operation known as image vectorization, and it is particularly valuable for logos and simple graphics.
Before converting JPG to SVG, it is necessary to know how the process works. A JPG is a raster image — a set grid of image pixels. An SVG is a vector image — a set of mathematical instructions that applications renders as the graphic.
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 jpg to scalable vector function provides the most flexibility. Open your JPG in Illustrator, highlight the image, access the Image Trace panel and pick an suitable option.
