png to gsp conversion is most likely related to the Silhouette Studio cutting design software, to be more precise to the import of PNG graphics for making new designs.
According to the software website, it supports import of PNG graphics just fine, so in this sense it should be possible to convert png to gsp, or at least reuse some parts of the graphics. GSP format is exclusive to Silhouette Studio, so it is unlikely any other software can be used for this though.
