Scalable Vector Graphics — vector graphics — is essentially distinct from JPG. Whereas JPG saves photos as a pixel grid, SVG saves graphics as geometric descriptions of geometric shapes. Which means SVG graphics can be displayed at every size — from a 16x16 pixel favicon to a billboard — without any loss of sharpness.
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 image.
Results are excellent for clean images with clear shapes and jpg to scalable vector minimal colors — logos, icons, silhouettes and illustrations. It does not work for complex photos with complex gradients.
For quality conversion, Adobe Illustrator's Image Trace tool offers the most control. Load the image in Illustrator, select the graphic, open the Image Trace settings and choose an relevant setting.
