This is a Windows Form app which is used to combine multiple PDF files in a single PDF file where you locate it with the app. I use both iTextSharp and PdfSharp NuGet packages. You can prefer both options to combine your PDF files. I tested this app a lot, but if you test and send me issues I will be so appreciated to you. This app is written in C# programming language and in Visual Studio 2017.
