png to csd conversion is typically searched by users that are looking for ways to create embroidery designs for their stitching machine (Poe, Huskygram, Singer) from a picture they got. This can be anything from simple motifs and pictures, to company logos and emblems.
What you need is dedicated embroidery software that supports digitizing/tracing function that will allow you to turn raster graphics (in this case PNG picture) to a vector based design in CSD format, typical for these machines.
