Here is how too upload and display a PDF on your WordPress site.
1. Go to the page you want to add the PDF too. Then click on the Upload/Insert link. Make sure before you do so, select the area on the page where you want the PDF link to go. It will automatically place it there when you are finished.
3. Upload the PDF.
6. That tag opens up a window image viewer when clicked. That will not display your PDF correctly, so we want to remove it. Then replace it with the code target=_blank. Now when the use clicks on the PDF link, it will open into a new browser window.
7. Now click ‘Publish’ and you are done! Click on ‘View Post’ to see the new page you created and test your link.
