The .pdf format lets anyone see your documents exactly as you want them to see them, and they can be made into slides as well as printed on paper. We set our software to enlarge or reduce your pages to fit onto a 35mm slide as best as possible, without cropping off any of the pages.Simply send us the .pdf file and tell us which pages to use to create slides. Please do not place any important text or images too close to the edges of the paper. Your pages may be either portrait or landscape, but you may not mix page sizes in one PDF file.
