using System.Linq;

// One or more images as IEnumerable. This example selects all JPEG images in a specific 'assets' folder.
var imageFiles = Directory.EnumerateFiles("assets").Where(f => f.EndsWith(".jpg") || f.EndsWith(".jpeg"));

// Converts the images to a PDF and save it.
ImageToPdfConverter.ImageToPdf(imageFiles).SaveAs("composite.pdf");

Images To PDF

Construct a PDF from one or more image files using the IronPdf.ImageToPdfConverter class.

How to Convert an Image to a PDF in C#

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

IronPdf.ImageToPdfConverter.ImageToPdf(@"C:\images\example.png").SaveAs("example.pdf");

IronPdf.ImageToPdfConverter.ImageToPdf(@"C:\images\example.png").SaveAs("example.pdf");

IronPdf.ImageToPdfConverter.ImageToPdf("C:\images\example.png").SaveAs("example.pdf")

VB C#

Combine Multiple Images Into a PDF File

We can also convert images to PDFs in batch into a single PDF document using System.IO.Directory.EnumerateFiles along with ImageToPdfConverter.ImageToPdf:

string sourceDirectory = "D:\web\assets";
string destinationFile = "JpgToPDF.pdf";
var imageFiles = Directory.EnumerateFiles(sourceDirectory, "*.jpg");
ImageToPdfConverter.ImageToPdf(imageFiles).SaveAs(destinationFile);

string sourceDirectory = "D:\web\assets";
string destinationFile = "JpgToPDF.pdf";
var imageFiles = Directory.EnumerateFiles(sourceDirectory, "*.jpg");
ImageToPdfConverter.ImageToPdf(imageFiles).SaveAs(destinationFile);

Dim sourceDirectory As String = "D:\web" & ChrW(7) & "ssets"
Dim destinationFile As String = "JpgToPDF.pdf"
Dim imageFiles = Directory.EnumerateFiles(sourceDirectory, "*.jpg")
ImageToPdfConverter.ImageToPdf(imageFiles).SaveAs(destinationFile)
