Simple GUI for pdftk. It can be used only for join, rotate and extract PDF-files. Nothing more. App requires .NET Framework 4.0+. C# source code available as project and can be compiled with SharpDevelop. The reason I wrote this tool is because I couldn’t find an open source GUI that supports the latest versions of pdftk.
