Scalable Vector Graphics — the SVG format — is fundamentally different from JPG. While JPG stores photos as a raster of pixels, SVG encodes illustrations as mathematical descriptions of paths and colors. This means SVG files can be displayed at any size — from a small icon to a large banner — without any pixelation.
Changing JPG to SVG is a technique known as image vectorization, and it is particularly valuable for illustrations and flat artwork.
When converting JPG to SVG, it is essential to know how the process works. A JPG is a raster image — a fixed grid of image pixels. SVG files are a mathematical image — a series of geometric shapes which software displays as the artwork.
Results are excellent for uncomplicated graphics with defined shapes and limited colors — logos, icons, silhouettes and flat artwork. It does not work for complex photos with thousands of colors.
For best output, Illustrator's Image Trace function gives the most flexibility. Load the image in Illustrator, select the image, access the Image Trace settings and pick an appropriate preset.
