SVG — the SVG format — is completely separate from JPG. JPG encodes pictures as a raster of pixels, SVG encodes illustrations as mathematical descriptions of shapes, lines and colors. This means SVG images scale to all sizes — from a small icon to a massive print — with no quality loss.
Changing JPG to SVG is a process called raster to vector conversion, and it is very beneficial for illustrations and clean graphics.
Prior to converting JPG to SVG, it is important to understand what the conversion actually does. JPG files are a pixel-based image more info — a fixed grid of pixels. SVG files are a mathematical image — a collection of paths that a browser displays as the artwork.
The conversion works great 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 tool provides the most precision. Open your JPG in Illustrator, highlight the image, access the Image Trace settings and choose an relevant setting.
