When you finish the course, we'll send you an e-mail with your diploma. If you would like to save it in PDF format, just select the diploma (by dragging it with the mouse as if it were text) and select the Print command with the right mouse button. A dialog box will open for you to confirm printing: change the "Destination" option to "Save as PDF"
(You may need to install a pdf printer, for example Primo PDF. You can download it here: http://www.primopdf.com/es/).
To save it with the correct format, select "Landscape" in the "Layout" section.
