Vector graphics are images created from lines and directions. They differ from raster graphics in that they can easily scale to any size without pixelation, as the lines are redrawn whenever it is resized. Converting a raster, or pixel-based, image is tricky due to the inherent differences in the formats. You’ll essentially be tracing over the original image to recreate it in vector format. There are tools that can handle the heavy lifting of this process, but you’ll likely need to do some manual editing to get the final product looking just right.
