Note: Most diecutting software including SCAL, MTC and Silhouette Studio have at least basic tracing functionality so that Inkscape is not usually needed any more. Though it is largely obsolete for diecutters, I am leaving this page up for those who want an alternate method or to learn basic Inkscape skills for other applications…
The question comes up all the time, “How can I make my jpg into an svg?” or something similar to that. You will need a vector editor, with tracing functions, but other than that, the answer depends on what kind of image you are starting with and what kind of svg you want for cutting. There are dozens of Inkscape tutorials on converting bitmap images (jpg, bmp, png, tiff) to svg, so here’s a pictorial index I hope will help you find the right one.
Pick a tutorial to help you trace (vectorize)…
If your image is a silhouette or one color logo
If your image is a grayscale/silhouette
If your image is a line art shape/template
