I think it’s worth mentioning, SVG compression ratio depends on the variations of color in an image. For example the above Twitter icon has only 2 different colors, using SVG is gonna save you from lots of pain. If it had more than 2 colors for example 1000 different colors (like our regular captured picture has) then the SVG format would have taken a way more space than PNG, JPG. It’s really great to use SVG when it comes to icon, logo, and simple illustration.
