I would like to add a link to an external website to a set of PDF files - Ultimately each file would have this link in the upper left hand corner. Is there a way to automate this, much like the automation Photoshop offers? I looked through the batch processing and I didn't have any luck finding what I am trying to do. Has anyone ever tried doing this?
Acrobat pro doesn't have a lot of manual or interface based batch operations for links, other than scanning a document's text and making text based URLs, or at least whatever it thinks are URLs, and making them into live links.
So if you have a typed URL of editable text in your PDF, you can go that route and check it, save, done...
OR... if you have a graphic in your doc and want to make it a "button", you may want to try this :
If you build your doc in InDesign you can create links for PDF export.
If you create a template or "Master page" layout in indesign with this, this template can be applied to all pages immediately.
This template can be a transparent rectangle and overlay your existing design.
It's possible to import an entire PDF into InDesign and apply this template to the whole doc and then resave as a PDF.
to do this in inDesign make an object, like a rectangle and right click or CTRL+click the item.
Choose interactive, and choose the type of interaction, like convert to button, new hyperlink etc. - many of these options are IDENTICAL to the Adobe acrobat pro dialogues...
You can then set this up as a master page, and apply it easily and quickly.
I'm sorry I don't have as elegant a solution in Acrobat, but this will hopefully help you more than just a simple "no" to your question.
you can use acrobat to make a link and copy and paste the invisible rectangle on each page, while tedious, it's another option.
