Why does Cricut need SVG instead of PNG for cutting?
Cricut Design Space does accept PNG files for print-then-cut projects, where it prints the image and cuts around the outline. What it can't do with a PNG is follow precise internal cut lines - a PNG is a grid of pixels with no path data, so there's nothing for the blade to trace beyond the outer edge. SVG gives Design Space the actual vector path data it needs to cut detailed shapes.
