SVG — the SVG format — is completely separate from JPG. JPG encodes pictures as a grid of pixels, SVG encodes illustrations as mathematical descriptions of paths and colors. Meaning SVG graphics scale to any size — from a 16x16 pixel favicon to a billboard — without any pixelation.
Transforming JPG to SVG is a technique known as image vectorization, and it is especially useful for logos and simple graphics.
When converting JPG to SVG, it is necessary to know how the process works. A JPG is a raster image — a set grid of dots. An SVG is a vector image — a series of geometric shapes that applications renders as the more info image.
Results are excellent for clean images with clear shapes and minimal colors — icons, logos, symbols and illustrations. It does not work for complex photos with complex gradients.
For quality conversion, Adobe Illustrator's Image Trace feature gives the most control. Load the image in Illustrator, select the graphic, open the Image Trace dialog and select an appropriate preset.
