If you are using a PC with Windows, Microsoft has a print to pdf program/app. To check just select to print it and go to the drop down menu that shows your printer options. Your default printer will probably be the one selected. Open the menu and see if "save as pdf" or "print to pdf" is an option.

I just opened one of the png files in photoshop and it is shown as being 72 dpi so it wouldn't enlarge very well. On the plus side, it's canvas measures close to 29 1/2 (75.11cm) inches by 44 3/4 inches (113.74cm) so the coach sides measure over 18 inches! :-D
