Scalable Vector Graphics — Scalable Vector Graphics — is fundamentally separate from JPG. Whereas JPG encodes photos as a grid of pixels, SVG saves graphics as geometric descriptions of geometric shapes. This means SVG files can be displayed at all sizes — from a 16x16 pixel favicon to a billboard — with no loss of sharpness.
Transforming JPG to SVG is a operation referred to as raster to vector conversion, and it is especially useful for illustrations and flat artwork.
Before converting JPG to SVG, it is necessary to realize what the conversion actually does. A JPG is a bitmap image — a fixed grid of pixels. SVG files are a vector image — a set of mathematical instructions that applications renders as the graphic.
The conversion works great for clean images with defined shapes and few colors — logos, icons, silhouettes and flat artwork. It does not work for detailed photographs with fine detail.
For professional results, Illustrator's Image Trace function offers the most flexibility. Open your JPG in Illustrator, highlight the image, check here access the Image Trace panel and select an appropriate preset.
