Scalable Vector Graphics — the SVG format — is completely separate from JPG. JPG encodes pictures as a grid of pixels, SVG stores images as mathematical descriptions of paths and colors. Meaning SVG images scale to any size — from a 16x16 pixel favicon to a massive print — without pixelation.
Changing JPG to SVG is a operation called vectorization, and it is very beneficial for illustrations and flat artwork.
Prior to converting JPG to SVG, it is essential to understand what the conversion actually does. JPG files are a pixel-based image — a static grid of pixels. SVG files are a mathematical image — a collection of paths that a browser uses to draw the artwork.
The conversion works great for simple images with distinct shapes and few colors more info — logos, icons, silhouettes and flat artwork. Results are poor for photographic images with thousands of colors.
For best output, Adobe Illustrator's Image Trace function provides the most precision. Open your JPG in Illustrator, highlight the image, access the Image Trace panel and pick an suitable option.
