How to Convert an Image to a PDF in C#

Given a single image located on a computer at C:\images\example.png, you can quickly convert it into a PDF document by calling the IronPdf.ImageToPdfConverter.ImageToPdf method with its file path:

// Convert a single image to a PDF.
var pdf = IronPdf.ImageToPdfConverter.ImageToPdf(@"C:\images\example.png");
// Save the resulting PDF to the specified location.
pdf.SaveAs("example.pdf");

// Convert a single image to a PDF.
var pdf = IronPdf.ImageToPdfConverter.ImageToPdf(@"C:\images\example.png");
// Save the resulting PDF to the specified location.
pdf.SaveAs("example.pdf");

' Convert a single image to a PDF.
Dim pdf = IronPdf.ImageToPdfConverter.ImageToPdf("C:\images\example.png")
' Save the resulting PDF to the specified location.
pdf.SaveAs("example.pdf")

Combine Multiple Images Into a PDF File

You can also convert multiple images into a single PDF document using System.IO.Directory.EnumerateFiles along with ImageToPdfConverter.ImageToPdf:

// Define the source directory containing the images.
string sourceDirectory = @"D:\web\assets";
// Define the path for the resulting PDF.
string destinationFile = "JpgToPDF.pdf";

// Get all image files in the source directory with a .jpg extension.
var imageFiles = System.IO.Directory.EnumerateFiles(sourceDirectory, "*.jpg");

// Convert the images into a single PDF.
var pdf = IronPdf.ImageToPdfConverter.ImageToPdf(imageFiles);

// Save the resulting PDF to the specified location.
pdf.SaveAs(destinationFile);

// Define the source directory containing the images.
string sourceDirectory = @"D:\web\assets";
// Define the path for the resulting PDF.
string destinationFile = "JpgToPDF.pdf";

// Get all image files in the source directory with a .jpg extension.
var imageFiles = System.IO.Directory.EnumerateFiles(sourceDirectory, "*.jpg");

// Convert the images into a single PDF.
var pdf = IronPdf.ImageToPdfConverter.ImageToPdf(imageFiles);

// Save the resulting PDF to the specified location.
pdf.SaveAs(destinationFile);

' Define the source directory containing the images.
Dim sourceDirectory As String = "D:\web\assets"
' Define the path for the resulting PDF.
Dim destinationFile As String = "JpgToPDF.pdf"

' Get all image files in the source directory with a .jpg extension.
Dim imageFiles = System.IO.Directory.EnumerateFiles(sourceDirectory, "*.jpg")

' Convert the images into a single PDF.
Dim pdf = IronPdf.ImageToPdfConverter.ImageToPdf(imageFiles)

' Save the resulting PDF to the specified location.
pdf.SaveAs(destinationFile)
