How To Copy Pages From One PDF Document Into Another PDF Document

This example shows how to extract pages from one PDF document (“Text.pdf”) and merge them with another existing document (“Images.pdf”) and then save them into “MergeDocument.pdf” document file.

Merge pdf documents

C# :

using PDFMosaic;
using System;

namespace MergePDFs
class MergePDFs
static void Main(string[] args)
// Open the first document
PDFDocument documentImages = new PDFDocument(“Images.pdf”);
// Open the second document
PDFDocument documentText = new PDFDocument(“Text.pdf”);

// Copy pages from one pdf to another pdf
for(int i = 0; i < documentText.Pages.Count; ++i)

// Save merged document
documentImages.Save(“MergeDocument.pdf”, true);

Visual Basic.NET :

Imports PDFMosaic
Imports System

Module MergePDFs
Sub Main()
‘ Open the first document
Dim documentImages As New PDFDocument(“Images.pdf”)
‘ Open the second document
Dim documentText As New PDFDocument(“Text.pdf”)

‘ Copy pages from one pdf to another pdf
Dim i As Integer
For i = 0 To documentText.Pages.Count-1

‘ Save merged document    
documentImages.Save(“MergeDocument.pdf”, True)
End Sub
End Module
