Prerequisites

Before we dive into the conversion process with GroupDocs.Conversion for .NET, ensure you have the following set up:

Install GroupDocs.Conversion for .NET

You can download the GroupDocs.Conversion for .NET library from the download page and follow the installation instructions provided there.

Basic Understanding of C#

Familiarity with the C# programming language is essential, as our examples will use C# code snippets to demonstrate the conversion process.

Integrated Development Environment (IDE)

You’ll need an Integrated Development Environment (IDE) to write and run your code. Popular choices include Visual Studio or JetBrains Rider.

Source File(s) for Conversion

Make sure you have the source file(s) ready for conversion. For example, if you’re interested in converting JPEG to PDF, have your JPEG file(s) accessible.

Importing Namespaces

Start by importing the necessary namespaces in your C# project:

using System;
using System.IO;
using GroupDocs.Conversion.Options.Convert;

Step 1: Define Output Directory and File Name

Determine where your converted PDF will reside, and set the name for your output file:

string outputFolder = "Your Document Directory"; // Specify your directory
string outputFile = Path.Combine(outputFolder, "jpeg-converted-to.pdf"); // Set output file name

Step 2: Load the Source JPEG File

Use the Converter class from GroupDocs.Conversion to load your JPEG file:

using (var converter = new GroupDocs.Conversion.Converter(Constants.SAMPLE_JPEG))
{
    // Conversion code will go here
}

Step 3: Set Conversion Options

Define the conversion options. For converting JPEG to PDF, you’ll use PdfConvertOptions:

var options = new PdfConvertOptions(); // Create PDF conversion options

Step 4: Execute the Conversion

Invoke the Convert method to execute the format change. Pass in your output file path along with the conversion options:

converter.Convert(outputFile, options); // Perform the conversion

Step 5: Display a Completion Message

Once the conversion is complete, it’s good practice to inform the user. You can add the following line:

Console.WriteLine("\nConversion to PDF completed successfully.\nCheck output in {0}", outputFolder);
