Merge documents to PDF

Introduction

Consider the functionality for merging files of various formats such as PDF, DOC, PPT and XLS into a PDF document. Let’s see, why do we need to combine these files into a PDF document? This article discusses the PDF format, but those ones will be more in the near future. But turn back to the PDF format. It is a standard format that allows you to display information the same on any device with any platform. It is comfortable for transferring info via the Internet or to a printer. That is why this format is chosen for the current task of combining files of various formats.

Merge documents to PDF

Multiple files (even different types of files such as DOC, PPT, XLS) can be combined into a single PDF file by using GroupDocs.Merger API. You can also use this join method to combine multiple PDF files. This cross-format merge to PDF could be useful for the cases when there is no ability to merge only PDF files. For now, GroupDocs.Merger API allows to join other file types without password with the PDF document loaded into Merger object.

The following example demonstrates how to merge PDF file with DOC, PPT and XLS file types:

Merger merger = new Merger("c:\document1.pdf");
{
    merger.join("c:\document2.doc");
    merger.join("c:\document3.ppt");
    merger.join("c:\document4.xls");
    merger.save("c:\merged.pdf");
}
