Scalable Vector Graphics — the SVG format — is essentially different from JPG. Whereas JPG stores images as a grid of pixels, SVG encodes images as geometric descriptions of shapes, lines and colors. This means SVG files work at all sizes — from a small icon to a massive print — without pixelation.
Transforming JPG to SVG is a process called vectorization, and it is particularly valuable for illustrations and flat artwork.
When converting JPG to SVG, it is important to understand how the process works. A JPG is a bitmap image — a set grid of dots. An SVG is a scalable image — a series of geometric shapes that applications renders as the image.
Results are excellent 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 feature website gives the most flexibility. Load the image in Illustrator, click the graphic, open the Image Trace panel and select an appropriate preset.
