Considering both PES (Brother) and DST (Tajima) embroidery design formats are fairly common, most embroidery programs should support both of at least one of these formats and allow various conversions, including pes to dst conversion. You can even find some dedicated embroidery design converters, but embroidery software usually is safer choice especially if you aim for some particular program or format.
