SVG — the SVG format — is essentially different from JPG. Whereas JPG stores photos as a raster of pixels, SVG saves illustrations as mathematical descriptions of shapes, lines and colors. This means SVG files scale to every size — from a tiny icon to a massive print — without loss of sharpness.
Converting JPG to SVG is a operation known as raster to vector conversion, and it is particularly valuable for icons and clean graphics.
When converting JPG to SVG, it is necessary to understand how the process works. A JPG is a pixel-based image — a static grid of dots. An SVG is a vector image — a series of geometric shapes that applications uses to draw the image.
Results are excellent for clean images with clear shapes and minimal colors — icons, logos, symbols and line art. It does not work for detailed photographs with fine detail.
For professional results, Adobe Illustrator's Image Trace function provides the most precision. Open your JPG in Illustrator, highlight the image, access the Image Trace dialog and choose an appropriate website preset.
