What’s an SVG, and why do I have to use it? SVG, or Scalable Vector Graphics, are very small in file size and are great for retina displays. Vector graphics have an advantage over pixel formats like .gif or .jpg as they don’t deal with resolution. SVGs can scale to any size and not lose clarity. All SVGs are usually smaller in file size than raster graphics.
