If you are looking to merge multiple PDF files into a single PDF file, Apryse has an SDK that can combine PDF files easily.

The Apryse SDK is available for .NET, .NET Core, Java, and more. In addition to PDF file merge, the SDK provides much more including getting information about the file, getting PDF metadata, encrypting and decrypting PDFs, distilling PostScript to PDF, digital signing, bookmarking, annotating, and web optimizing.

Below are some C# and Java code snippets that can be used to combine PDF files into one PDF file.
