1) Go to the “media library” and select “add new”. Choose the pdf you want to add from your own device – make sure it has a sensible name. This document will now be in the media library .
2) Now click on the pdf document in the media library. On the right hand side you will see information about the pdf. You need the URL, so copy it.
3) You now need to create the hyperlink. On the page or post where you would like the link to appear, type the words you would like to be the link. Usually the name of the document. Now highlight the these words in the same way as for a hyperlink and click on the link icon. A new window opens and you now need to paste the URL of the pdf (that you just copied in part 2) in the URL box. Add a title (this is what the user will see if they hover on the link). Tick “open link in a new window” because the pdf will not have any of the menus, header etc. so you want your site still to be there when someone shuts the document.
4) Now click “add link” and update or publish your page or post in the same way as usual. Test out the link and make sure the pdf opens. Remember you have to view the post or page to do this you cannot link while in edit mode.
