Scalable Vector Graphics — Scalable Vector Graphics — is essentially distinct from JPG. Whereas JPG saves photos as a raster of pixels, SVG encodes illustrations as mathematical definitions of shapes, lines and colors. This means SVG images work at all sizes — from a small icon to a large banner — 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 SVG, it is important to understand what the conversion actually does. JPG files are a pixel-based image — a static grid of pixels. SVG files are a scalable image — a collection of paths which software uses to draw the artwork.
The conversion works more info great for clean images with clear shapes and minimal colors — logos, icons, silhouettes and flat artwork. 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.
