The easiest way to separate your multipage PDF into singular pages, is using Adobe Acrobat. Simply open the PDF, and follow these steps.
- Click "Document>Split Document" from the top menu bar.
- Select to split the document by number of pages, and enter the max number of pages as 1
- Click OK
- Now the single page PDFs should be saved in the same folder as the original on your PC.
If you do not have a copy of Adobe Acrobat, you may find some useful information in the Adobe Forums.
