This tool converts a standard PDF file into a printable booklet. This means it's not exactly readable as a PDF, but when you print it out properly, it will look like a booklet. This does require a printer which is capable of double sided printing. Once you have your converted booklet, you may have to change some settings to print it as a booklet. The crucial thing you need to do is print it double sided, but flipped on the long edge. See a video on how to do this below.
