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 shapes, lines and colors. This means SVG images scale to all sizes — from a small icon to a massive print — without quality loss.
Changing JPG to SVG is a operation called 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 displays as the graphic.
This works extremely well for uncomplicated graphics with defined shapes and limited colors — icons, logos, symbols and line art. Results are poor for photographic website images with fine detail.
For best output, Illustrator's Image Trace function provides the most flexibility. Open your JPG in Illustrator, highlight the image, access the Image Trace panel and pick an suitable option.
