The image you posted is a rendered photo which is computed pixel per pixel with many different colors, therefore it's difficult to vectorize it to obtain a similar image in SVG format. Among the free converters available on Internet I tried with your image, pngtosvg.com seemed to give "acceptable" results.
But maybe your could simply use the image returned by Plan > Export to SVG format menu item.

Blender supports very well OBJ format import and export.
