It is also subjective what a good conversion means in different contexts. It is an extremely difficult math problem to figure out how to convert dots to directions.

Well, the simple answer is it takes a lot of math. So what’s the big deal, why can’t we just convert a bitmap image to a vector image easily?

SVG files are image files that contain directional information or paths information about the image. It wants to know what path to take to make the cut. It needs directional (or vector) information. Unfortunately, the blade in the Cricut needs additional information. It wants to know what color to use for each dot in the image. This is useful for most printers because that is how it processes information to print. The image file records the image with information on each pixel. Bitmap images are composed of pixels (or dots). Most digital images you see are bitmap images. Why can’t you use regular JPG or PNG images to cut? There are other vector file formats but SVG is the most common and is the one that Cricut uses for all its machines. It is a type of vector file that most cutting machines use to determine what direction to send the blade.
