SVG — the SVG format — is completely different from JPG. Whereas JPG saves photos as a grid of pixels, SVG saves illustrations as mathematical descriptions of shapes, lines and colors. This means SVG images can be displayed at all sizes — from a 16x16 pixel favicon to a billboard — without any loss of sharpness.
Changing JPG to SVG is a operation referred to as vectorization, and it is especially useful for illustrations and flat artwork.
Before converting JPG to SVG, it is necessary to understand what the conversion actually does. A JPG is a raster image — a fixed grid of image pixels. SVG files are a scalable image — a set of mathematical instructions that a browser uses to draw the graphic.
This works extremely well for simple images with clear shapes and limited colors click here — icons, logos, symbols and flat artwork. It does not work for detailed photographs with complex gradients.
For quality conversion, Adobe Illustrator's Image Trace tool offers the most control. Load the image in Illustrator, select the image, access the Image Trace settings and choose an suitable option.
