Create Links from Web Addresses

Text and Images from Slide

Edit PDF tools in the Tools Task Pane, Activate the Link tool and choose "Create links from web addresses."
This tool looks for whole web addresses and most likely not create a link that starts with "www" or just has the main web address like karlencommunications.com.
Review the document before you run the tool so that when you get the message telling you how many links were added, you know if it missed any.
You'll have to add them manually.
