Scalable Vector Graphics — the SVG format — is completely separate from JPG. While JPG stores images as a grid of pixels, SVG stores images as geometric descriptions of paths and colors. Meaning SVG graphics scale to any size — from a 16x16 pixel favicon to a billboard — without pixelation.
Transforming JPG to SVG is a technique known as image vectorization, and it is especially useful for logos and simple graphics.
When converting JPG to SVG, it is necessary to know 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 displays as the graphic.
This works extremely well for simple images with distinct shapes and few colors — logos, icons, silhouettes and line art. Results are poor for photographic images with thousands of colors.
For best output, Illustrator's Image Trace function provides the most precision. here Open your JPG in Illustrator, highlight the image, access the Image Trace settings and pick an suitable option.
