Question:
Can Win2PDF create a PDF in booklet format?

Answer:
Win2PDF cannot create a PDF in booklet format directly, but it can create one if you print the PDF from Adobe Reader to the Win2PDF printer and select the "booklet" option from Adobe Reader.  More information on the Adobe Reader booklet feature is at:
