Convert PDF to VSD

Converting Adobe Portable Documents directly to Microsoft Visio Drawings (.pdf to .vsd conversion) seems very unlikely, even though several online conversion tools claim they are capable of such a conversion. The actual quality of such supposed conversions is highly questionable, at best.

You could try to create vector graphics from a diagram (.vmf / .emf / .svg), and import it to MS Visio. Such conversion will obviously not be perfect, and you will be left with loss of data.

Simply put, it is impossible to convert PDF to VSD directly.
Thus, there is no so-called pdf to vsd converter or a free online .pdf to .vsd converter to be found.
