Pdftk is a simple tool for doing everyday things with PDF documents. If PDF is electronic paper, then pdftk is an electronic stapler-remover, hole-punch, binder, secret-decoder-ring, and X-Ray-glasses.
Pdftk is a front end to the iText library. It’s capable of splitting, merging, encrypting, decrypting, uncompressing, recompressing, and repairing PDFs. It can also be used to manipulate watermarks, metadata, and forms.
It’s a very versatile toolkit.
