You could also check out pdftk. It's a pretty powerful document processing tool.

EDIT:

Try using PDF Chain to overlay two pdfs. You can place your watermark as required in a file and place it behind every page of main document.
Then extract 1st page using pdftk and convert it to jpg or image format using convert command (available with the imagemagick package).

Thanks Sidhant. Any ideas on how I might do a preview on the front end to show where the stamp would be placed?

Re: preview of the stamp on the PDF - I was seeking a web based solution, i.e. something that is shown in the browser so the use doesn't need to leave the web application.

These are all command line tools you can access on your backend. You can you run this on your server and send the response back to your web app
