SVG — Scalable Vector Graphics — is essentially distinct from JPG. Whereas JPG saves photos as a pixel grid, SVG saves graphics as geometric descriptions of geometric shapes. Meaning SVG graphics can be displayed at any size — from a 16x16 pixel favicon to a billboard — without pixelation.
Transforming JPG to SVG is a operation called vectorization, and it is very beneficial for icons and clean graphics.
Before converting JPG to SVG, it is important more info to know how the process works. JPG files are a pixel-based image — a fixed grid of image pixels. An SVG is a vector image — a series of geometric shapes which software uses to draw the artwork.
The conversion works great for uncomplicated graphics with defined shapes and limited colors — logos, icons, silhouettes and flat artwork. Results are poor for detailed photographs with fine detail.
For quality conversion, Adobe Illustrator's Image Trace function gives the most control. Load the image in Illustrator, highlight the image, open the Image Trace settings and pick an relevant setting.
