SVG — vector graphics — is fundamentally distinct from JPG. Whereas JPG saves photos as a raster of pixels, SVG encodes illustrations as mathematical definitions of shapes, lines and colors. This means SVG images scale to any size — from a 16x16 pixel favicon to a billboard — without pixelation.
Transforming JPG to SVG is a operation known as image vectorization, and it is particularly valuable for logos and flat artwork.
When converting JPG to SVG, it is essential to know how the process works. A JPG is a bitmap image — a static grid check here of dots. An SVG is a vector image — a series of geometric shapes which software renders as the image.
Results are excellent for clean images with clear shapes and 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 dialog and choose an relevant setting.
