PDFTK Builder

PDFTK Builder is a small tool that lets you make certain changes to PDF documents. In particular, PDFTK Builder allows to combine several PDFs into one and indicate the page ranges to be included from each. It's also possible to restrict the edits that other users can make to the file. If you want to prevent your content from being copied, you can untick the corresponding box. You can do the same to prevent users from printing, adding information, making changes, etc. It's also possible to restrict who can open the document by adding a password. Other operations you can complete with PDFTK Builder include: saving each page of the PDF separately, adding a watermark from another PDF file, or rotating selected pages.
