Scalable Vector Graphics — Scalable Vector Graphics — is essentially 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 any size — 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 illustrations and flat artwork.
When converting JPG to SVG, it is essential to understand what the conversion actually does. A JPG website is a bitmap image — a static grid of dots. An SVG is a scalable image — a series of geometric shapes which software uses to draw the artwork.
Results are excellent for clean images with clear shapes and minimal colors — logos, icons, silhouettes and illustrations. It does not work for complex photos with complex gradients.
For quality conversion, Adobe Illustrator's Image Trace tool offers the most control. Load the image in Illustrator, select the graphic, open the Image Trace dialog and choose an relevant setting.
