I need a way to insert a hyperlink in PDF files that have not been
created by me. An example of such PDF file can be found at:

Thank you!

Hi MrFash1, 

Inserting a hyperlink isn't very hard, but you will need the full
version of Adobe Acrobat, and not just the free Reader.  You can get a
free 30 day tryout version of Acrobat Pro here:

If you wish to purchase Acrobat Pro the best price I've found for it
is here for $139: http://www.micromasteronline.com/store/1198prod.html

To insert a hyperlink in a PDF is quite simple.  Using the example of
the file you linked to, let's say you wanted a hyperlink on the text
heading APC Series.  In Acrobat 6.0 Pro you need to:

- click the Select Text button (on the button bar beside the hand) to
get a text selection cursor.

- right-click the highlighted text and select 'Create Link'.

- select 'Open a web page' and enter its address, or link to another
file or page in the document, depending on what you want the link to
do.

And that's all there is to it.

Some PDF files may be created with access restrictions that prevent
you from editing them.  In this case it will not be possible to add
hyperlinks unless you are the creator of the document.

I hope this helps you out.
