PDFTK Builder is a free utility tool by indie developer Angus Johnson that can be used on PC devices. It is a PDF editor that lets users change or modify the contents of their PDF documents. It also provides some basic management features that can add password protection to files.

PDFTK Builder works in a similar way to other programs like PDF-XChange Editor or Foxit Advanced PDF Editor. It takes a more simplistic approach, though, by providing just the essential features and functions in a PDF editor. It comes with a straightforward user interface that is easy to use.

How do I use PDFTK Builder?

PDFTK Builder has an intuitive user interface that is easy to understand and navigate. Its feature set is divided into four tabs located at the top. The first is called Join Files wherein you can collate multiple PDF documents into a single file in any order that you want. The second tab is Split, and it lets you separate each page of your PDF into individual files.

If you want to add backgrounds, stamps, or numbering to your pages, you can do that in the Background/Stamp tab. Lastly, there's the Rotate section that lets you change the orientation of pages, with an option to only apply changes to specific pages. Persistent throughout the UI is the bottom half that contains two more features. One is letting you set a password for yourself or another user.

The other one is letting you allow modifications and other various actions to be done to your PDF file. There are no other advanced features like more extensive editing tools or per page modification options to be found here, though. If you find these features necessary to your use case, PDFTK Builder might not be the best solution for you.

All the basics covered

In conclusion, PDFTK Builder is a handy program for managing and making simple changes to your PDF documents. It's fast and lightweight, covers all the basics, and it's intuitive to use. If you need a more comprehensive set of tools for editing, you might want to consider something else. Otherwise, this one is worth trying out.
