Let's begin by creating a C# project.

• Open Visual Studio.
• Create a new C# Project.
• Give a name to the project.
• Select a .NET Core version for your project. It is recommended to use .NET 6.0 for this project.

2. Install the IronPDF Library

3. Add the IronPDF Namespace

To use IronPDF features, you need to add the IronPDF namespace to your program. Add the provided line of code to the top of the file.

using IronPdf;

using IronPdf;

Imports IronPdf

This will allow you to access the functions of the IronPDF library. You are required to add this line of code to every file to use the IronPDF features.

4. Convert JPG Images to PDF Format

The conversion of JPG images to PDF files can be achieved in a single line with IronPDF. The code is neat, clean, and understandable. This task can be achieved using IronPDF's ImageToPdfConverter method. Follow the steps below to convert any JPG image to a PDF document.

First, place all JPG file formats to be converted inside a folder named "assets" located in the directory of the project. The folder must be placed in the location: bin\Debug\net6.0.

Then using System.IO.Directory, enumerate the assets folder with all the JPG files and pass it to the ImageToPdf method for PDF conversion. The following code snippet helps convert JPG to PDF images and saves them to a new document.

using IronPdf;

Console.WriteLine("C# Convert Images (JPG to PDF) using IronPDF");

// Selects all JPG/JPEG images in the folder 'assets'.
var images = System.IO.Directory.EnumerateFiles("assets")
                                .Where(f => f.EndsWith(".jpg") || f.EndsWith(".jpeg"));

// Converting images to PDF and saving the result as "composite.pdf".
ImageToPdfConverter.ImageToPdf(images).SaveAs("composite.pdf");

// Print success message
Console.WriteLine("JPG successfully converted to PDF using C#");

using IronPdf;

Console.WriteLine("C# Convert Images (JPG to PDF) using IronPDF");

// Selects all JPG/JPEG images in the folder 'assets'.
var images = System.IO.Directory.EnumerateFiles("assets")
                                .Where(f => f.EndsWith(".jpg") || f.EndsWith(".jpeg"));

// Converting images to PDF and saving the result as "composite.pdf".
ImageToPdfConverter.ImageToPdf(images).SaveAs("composite.pdf");

// Print success message
Console.WriteLine("JPG successfully converted to PDF using C#");

Imports IronPdf

Console.WriteLine("C# Convert Images (JPG to PDF) using IronPDF")

' Selects all JPG/JPEG images in the folder 'assets'.
Dim images = System.IO.Directory.EnumerateFiles("assets").Where(Function(f) f.EndsWith(".jpg") OrElse f.EndsWith(".jpeg"))

' Converting images to PDF and saving the result as "composite.pdf".
ImageToPdfConverter.ImageToPdf(images).SaveAs("composite.pdf")

' Print success message
Console.WriteLine("JPG successfully converted to PDF using C#")

In the above code snippet, the assets folder can contain multiple JPG images. Each image will be added to the PDF document as a separate page.

The same code example can be used to convert multiple JPG files. The output contains three JPG images in a PDF document.
