>>1464713Vectors are scalable - they are created using mathematical points, so you can scale them all the fuck up to infinity, or scale them down, and their proportions will always stay the same.
These are great to make backgrounds with, because you can scale the same image to fit in an area 600 pixels high, 20000 pixels high, or even 20 pixels high, and the thing would look EXACTLY THE SAME.
The ones with just the background removed only have a finite scale before they become artifacted, choppy, blocky or blurry. These vectors (if as vectors and not rasterized images, as they are here in .png form) are crisp at any resize level.
