Delete pictures

So I want to delete Facebook but that’s were my daughter pictures are at I post them so in case I lose my phone i can always have them on there n save them onto another phone but I want to delete my social media but idk what I’m going to do to keep my pictures saved. 😭 in case I ever loose this phone I have all the pictures on or something happens to it I want to have the pictures on something to go back n save them again later on if that makes sense. I tried iCloud but I have to pay to be able to backup the rest of the pics since I have so many
