Scalable Vector Graphics — Scalable Vector Graphics — is essentially distinct from JPG. Whereas JPG saves photos as a pixel grid, SVG saves graphics as mathematical definitions of geometric shapes. Which means SVG files can be displayed at every size — from a tiny icon to a billboard — without any loss of sharpness.
Transforming JPG to SVG is a technique referred to as image vectorization, and it is especially useful for logos and simple graphics.
Before 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 set of mathematical instructions that applications renders as the 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 offers the most control. Load the image in Illustrator, select the graphic, open the Image Trace dialog and choose an relevant setting.
