Several embroidery design programs offer digitizing functions and can use a simple bitmap image (simple in design) and digitize i.e. create a vector based embroidery design from it. So with such programs you can convert images in TIF format (logos, emblems etc.) and create an embroidery design from it in one of typical formats like Brother PES, which is exactly what tif to pes conversion is.
