viralPDF brings full re-branding functionality (and more) to all your PDF files.
Unlike any other PDF customizing tool available today, it lets you use unlimited, re-brandable links and email-addresses, add an expiration date and more. It's a set of 2 downloadable Windows-apps that run on your local PC.
Use viralPDF to turn *any* PDF file into a viral marketing tool: eBooks, special reports, articles,... you name it!
