Transfer Sims 4 DLC?

I was just wondering, how do I transfer all of my Sims 4 packages from my PS4 to my PC because I have very many of the packages and do not want to purchase them again on the pc because I have used hundreds of dollars on Sims on my PS4 and want to change over to PC but I can’t because all of my packages is on my PS4 and I do not want to use the Internet and get all for free because that’s illegal.
