In the modern digital age, PDF files have become one of the most popular document formats. Whether it's a business report, an academic paper, or eBooks, PDFs offer a reliable and versatile platform to present information. However, sometimes you may have multiple PDF files that you want to merge into one document.

There are several tools available to help you merge PDF documents, including Adobe Acrobat Reader, which is widely considered to be the industry standard. However, not everyone has access to this program, as it can be quite expensive. In this article, we will show you how to merge PDF files without Adobe Acrobat Reader using two popular tools, SamPDF Basic and SmallPDF, and introduce you to IronPDF as an alternative solution.

Introducing IronPDF

While both PDFSam Basic and SmallPDF are excellent tools for merging PDF files, they do have some limitations. For example, PDFSam Basic only offers basic editing features, and SmallPDF requires an internet connection to use. If you need a more robust solution for PDF editing, you might consider IronPDF.

IronPDF standouts as a robust HTML to PDF converter, capable of rendering raw HTML content from strings, files, and URLs faithfully into its equivalent PDF format.

using IronPdf;

class Program
{
    static void Main(string [] args)
    {
        var renderer = new ChromePdfRenderer();

        // 1. Convert HTML String to PDF
        var htmlContent = "<h1>Hello, IronPDF!</h1><p>This is a PDF from an HTML string.</p>";
        var pdfFromHtmlString = renderer.RenderHtmlAsPdf(htmlContent);
        pdfFromHtmlString.SaveAs("HTMLStringToPDF.pdf");

        // 2. Convert HTML File to PDF
        var htmlFilePath = "path_to_your_html_file.html"; // Specify the path to your HTML file
        var pdfFromHtmlFile = renderer.RenderHtmlFileAsPdf(htmlFilePath);
        pdfFromHtmlFile.SaveAs("HTMLFileToPDF.pdf");

        // 3. Convert URL to PDF
        var url = "http://ironpdf.com"; // Specify the URL
        var pdfFromUrl = renderer.RenderUrlAsPdf(url);
        pdfFromUrl.SaveAs("URLToPDF.pdf");
    }
}
using IronPdf;

class Program
{
    static void Main(string [] args)
    {
        var renderer = new ChromePdfRenderer();

        // 1. Convert HTML String to PDF
        var htmlContent = "<h1>Hello, IronPDF!</h1><p>This is a PDF from an HTML string.</p>";
        var pdfFromHtmlString = renderer.RenderHtmlAsPdf(htmlContent);
        pdfFromHtmlString.SaveAs("HTMLStringToPDF.pdf");

        // 2. Convert HTML File to PDF
        var htmlFilePath = "path_to_your_html_file.html"; // Specify the path to your HTML file
        var pdfFromHtmlFile = renderer.RenderHtmlFileAsPdf(htmlFilePath);
        pdfFromHtmlFile.SaveAs("HTMLFileToPDF.pdf");

        // 3. Convert URL to PDF
        var url = "http://ironpdf.com"; // Specify the URL
        var pdfFromUrl = renderer.RenderUrlAsPdf(url);
        pdfFromUrl.SaveAs("URLToPDF.pdf");
    }
}
Imports IronPdf

IronPDF also doubles as a powerful PDF editing tool that enables users to manipulate, merge, and create PDF files with ease. Developers can use IronPDF to add text, images, and annotations, and convert PDF files to different file formats.

One of the main advantages of IronPDF is its flexibility. It can be used as a standalone desktop application or integrated into your web application using the IronPDF API. Additionally, IronPDF is compatible with both Windows and Mac operating systems, making it accessible to a wide range of users.

Merge PDF Files using IronPDF

Step 1: Install IronPDF

The first step in merging PDF files using IronPDF is to download and install the IronPDF library. You can install it using the NuGet Console. Use the following command to install IronPDF:

Install-Package IronPdf

Step 2: Import the IronPDF Library

Once you have installed IronPDF, you need to import the library into your project. This can be done by adding the following code to the top of your C# file:

using IronPdf;
using IronPdf;
Imports IronPdf
VB   C#

Step 3: Load the PDF Files

Next, you need to load the PDF files that you want to merge. You can do this using the PdfDocument.FromFile method. In the following example, we are loading two PDF files named A.pdf and B.pdf:

var firstPDF = PdfDocument.FromFile("A.pdf");
var secondPDF = PdfDocument.FromFile("B.pdf");
var firstPDF = PdfDocument.FromFile("A.pdf");
var secondPDF = PdfDocument.FromFile("B.pdf");
Dim firstPDF = PdfDocument.FromFile("A.pdf")
Dim secondPDF = PdfDocument.FromFile("B.pdf")
VB   C#

Step 4: Merge the PDF Files

Once you have loaded the PDF files, you can use the PdfDocument.Merge method to merge them into a single PDF file. In the following example, we are merging the "firstPDF" and "secondPDF" files:

var merged = PdfDocument.Merge(firstPDF, secondPDF);
var merged = PdfDocument.Merge(firstPDF, secondPDF);
Dim merged = PdfDocument.Merge(firstPDF, secondPDF)
VB   C#

Step 5: Save the Merged PDF File

Finally, you need to save the merged PDF file to your computer. You can do this using the SaveAs method. In the following example, we are saving the merged PDF file as "Merged.pdf":

merged.SaveAs("Merged.pdf");
merged.SaveAs("Merged.pdf");
merged.SaveAs("Merged.pdf")
VB   C#

The complete code to merge two PDF files using IronPDF is as follows:

using IronPdf;

var firstPDF = PdfDocument.FromFile("A.pdf");
var secondPDF = PdfDocument.FromFile("B.pdf");
var merged = PdfDocument.Merge(firstPDF, secondPDF);
merged.SaveAs("Merged.pdf");
using IronPdf;

var firstPDF = PdfDocument.FromFile("A.pdf");
var secondPDF = PdfDocument.FromFile("B.pdf");
var merged = PdfDocument.Merge(firstPDF, secondPDF);
merged.SaveAs("Merged.pdf");
Imports IronPdf

Private firstPDF = PdfDocument.FromFile("A.pdf")
Private secondPDF = PdfDocument.FromFile("B.pdf")
Private merged = PdfDocument.Merge(firstPDF, secondPDF)
merged.SaveAs("Merged.pdf")
VB   C#

By following these steps and using the IronPDF library, you can easily merge multiple PDF files into a single document using IronPDF.

Conclusion
