I believe Mark Emmer commented on that.? Just save them out of the program (export) as HTML files, I recall it is 50MB per file and they can be saved in chunks.? Use any HTML editor open them and save them as a PDF file.? I use WordPerfect 8 and yes I know it is old but so am I.? If you save them as PDF , unless you have a PDF editor you won't be able to modify them.? Also when you download them, make sure and make duplicates and only diddle with the duplicates.? In case you crash the one you are working on, you still have the untouched original.
