1. Introduction

Adobe's Portable Document Format (PDF) is widely used in various industries for tasks such as creating invoices. Developers also use the PDF format to produce documents that meet client specifications. Libraries have simplified the process of creating PDFs, and when selecting a library for a project, consider features like build, read, and convert capabilities.

2. IronPDF Features

IronPDF is a robust PDF SDK framework that facilitates the creation, reading, and editing of PDF documents. It converts HTML to PDF using the Chrome engine and supports various web components like Xamarin, Blazor, Unity, HoloLens apps, and more. It works with both online applications and traditional Windows Applications. IronPDF allows for the creation of aesthetically pleasing PDFs using HTML5, JavaScript, CSS, and images, and includes a powerful HTML-to-PDF converter.

3. Create PDF Documents from Images

IronPDF makes it easy to create PDFs from images.

Dim pdfdoc = ImageToPdfConverter.ImageToPdf("test.png").SaveAs("Resultimage.pdf")
Dim pdfdoc = ImageToPdfConverter.ImageToPdf("test.png").SaveAs("Resultimage.pdf")
VB.NET

By using the ImageToPdfConverter class, it is easy to use without creating any object for the class. The ImageToPdf method accepts the filename and path as a parameter and converts the given PNG file into the desired PDF. Finally, the SaveAs saves the generated PDF file in the desired location.

The below image shows the result of the above code.

This next example creates a PDF document from a list of images.

Dim lstimages As List(Of String) = New List(Of String)
lstimages.Add("test.png") lstimages.Add("demo.png")
Dim pdfdoc = ImageToPdfConverter.ImageToPdf(lstimages).SaveAs("Resultimage.pdf")
Dim lstimages As List(Of String) = New List(Of String)
lstimages.Add("test.png") lstimages.Add("demo.png")
Dim pdfdoc = ImageToPdfConverter.ImageToPdf(lstimages).SaveAs("Resultimage.pdf")
VB.NET

4. Create PDF Documents from Bitmap image objects

Several bitmap image objects can be converted to PDF files with just a few lines of code.

Imports system.Drawing
Imports IronPdf

Dim image = Bitmap.FromFile("test.png")
Dim doc = ImageToPdfConverter.ImageToPdf(image).SaveAs("Resultimage.pdf")
Imports system.Drawing
Imports IronPdf

Dim image = Bitmap.FromFile("test.png")
Dim doc = ImageToPdfConverter.ImageToPdf(image).SaveAs("Resultimage.pdf")
VB.NET

In the example above, a Bitmap object is created from the PNG file and used as a medium format to convert to a PDF file.

It is also possible to combine a collection (or List) of Bitmap objects into a single PDF:

Dim lstimages As List(Of IronSoftware.Drawing.AnyBitmap) = New List(Of IronSoftware.Drawing.AnyBitmap)
lstimages.Add(Bitmap.FromFile("test.png"))
lstimages.Add(Bitmap.FromFile("demo.png"))
Dim pdfdoc = ImageToPdfConverter.ImageToPdf(lstimages).SaveAs("Resultimage.pdf")
Dim lstimages As List(Of IronSoftware.Drawing.AnyBitmap) = New List(Of IronSoftware.Drawing.AnyBitmap)
lstimages.Add(Bitmap.FromFile("test.png"))
lstimages.Add(Bitmap.FromFile("demo.png"))
Dim pdfdoc = ImageToPdfConverter.ImageToPdf(lstimages).SaveAs("Resultimage.pdf")
VB.NET

Configure the behavior of the above method calls using a ChromePdfRenderOptions object aids to enhance the visual aspect of the output PDF file. Options that can be configured include the position of the image, header and footer formatting, page title, page size, and many others.

More information about adding images to PDFs using IronPDF, along with other information, can be found in the IronPDF Documentation.
