SVG — the SVG format — is completely 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 billboard — without any loss of sharpness.
Transforming JPG to SVG is a technique known as image vectorization, and it is especially useful for icons and simple graphics.
Before converting JPG to SVG, it is necessary to realize what happens. A JPG is a raster image — a fixed grid of image pixels. An SVG is a mathematical image — a set of mathematical instructions that a browser displays as the graphic.
This works extremely well for simple images with distinct shapes and few colors — logos, icons, silhouettes and flat artwork. Results are poor for photographic images with thousands of colors.
For best output, Adobe Illustrator's Image Trace function provides the most precision. Open your JPG in Illustrator, highlight the image, access more info the Image Trace settings and choose an suitable option.
