DigiSigner

DigiSigner is a tool that allows you to add your signature to any PDF document by following just a couple simple steps.

Just choose the page that you'd like to bear your signature, select the name you'd like to use (the free version forces you to use a preset name), and proceed with total confidence.

Once the document is signed, you can save it and distribute it knowing that everyone will know that it's yours.

DigiSigner is an interesting application for any user who frequently works with PDF documents, since it will allow you to efficiently conserve and display authorship.
