How to Convert HTML Page to PDF using VB

This tutorial will demonstrate how to convert HTML to PDF using the most efficient VB.NET IronPDF library.

How to Convert HTML Page to PDF Using VB

1. Download and install the HTML to PDF converter VB library.
2. Create a renderer object using the IronPdf.ChromePdfRenderer() method.
3. Use the renderer.RenderHtmlAsPdf method to convert HTML to PDF using a string filename.
4. Save the PDF file using the SaveAs method.
5. Run the program to see the results.

3. Convert HTML to PDF Document Using IronPDF and VB Programming Language

The process of generating PDFs from HTML content and files is both intriguing and conveniently achievable with the utilization of IronPDF. In the forthcoming sections, we will delve into illustrative examples that demonstrate the seamless conversion of both HTML strings and HTML files into meticulously crafted PDF documents.

3.1. HTML String to PDF Document

IronPDF provides the feature to convert HTML to PDF documents using the VB programming language with just a few lines of code. Let's see how this works in the sample code snippet below.

Imports IronPdf

Module Module1
    Sub Main()
        ' Create a new PDF renderer using IronPDF.
        Dim renderer = New ChromePdfRenderer()

        ' Convert a simple HTML string to a PDF document.
        Dim document = renderer.RenderHtmlAsPdf("<h1> My First PDF in VB.NET</h1>")

        ' Save the resulting PDF document to a file.
        document.SaveAs("MyFirst.pdf")
    End Sub
End Module

Imports IronPdf

Module Module1
    Sub Main()
        ' Create a new PDF renderer using IronPDF.
        Dim renderer = New ChromePdfRenderer()

        ' Convert a simple HTML string to a PDF document.
        Dim document = renderer.RenderHtmlAsPdf("<h1> My First PDF in VB.NET</h1>")

        ' Save the resulting PDF document to a file.
        document.SaveAs("MyFirst.pdf")
    End Sub
End Module

This sample code snippet first imports the IronPDF namespace, which contains the classes and methods used to work with PDF documents. Then, it creates a new rendering engine object, which is used to convert HTML to PDF. The RenderHtmlAsPdf method of the renderer object takes an HTML string as its input and returns a Document object that represents the PDF document. Finally, the SaveAs method of the Document object is used to save the new PDF document to a file.

3.2. HTML File To PDF Document

In the following section, we will explore the process of converting an HTML page into a PDF format using the IronPDF library. To begin, you can either generate a new HTML file by writing HTML code or utilize an existing one as your starting point.

3.2.1. HTML Input File

HTML Input File

Imports IronPdf

Module Module1
    Sub Main()
        ' Create a new PDF renderer using IronPDF.
        Dim renderer = New ChromePdfRenderer()

        ' Convert an HTML file to a PDF document.
        Dim document = renderer.RenderHtmlFileAsPdf("invoice.html")

        ' Save the resulting PDF document to a file.
        document.SaveAs("invoice.pdf")
    End Sub
End Module

Imports IronPdf

Module Module1
    Sub Main()
        ' Create a new PDF renderer using IronPDF.
        Dim renderer = New ChromePdfRenderer()

        ' Convert an HTML file to a PDF document.
        Dim document = renderer.RenderHtmlFileAsPdf("invoice.html")

        ' Save the resulting PDF document to a file.
        document.SaveAs("invoice.pdf")
    End Sub
End Module

The above source code first creates an HTML form renderer object using the ChromePdfRenderer method, then converts the HTML file to PDF using the RenderHtmlFileAsPdf method. In the end, save the PDF file using the SaveAs method.
