SVG — vector graphics — is fundamentally different from JPG. While JPG stores images as a grid of pixels, SVG stores 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 vectorization, and it is very beneficial for illustrations and clean graphics.
Prior to converting JPG to jpg to scalable vector SVG, it is important to understand what happens. JPG files are a pixel-based image — a fixed grid of image pixels. SVG files are a mathematical image — a collection of paths that a browser displays 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 function provides the most flexibility. Open your JPG in Illustrator, click the image, access the Image Trace panel and pick an appropriate preset.
