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 VB programming language with just a few lines of code. Let's see how this works in the below sample code snippet.

Imports IronPdf
Module Module1
    Sub Main()
        Dim renderer = New ChromePdfRenderer()
        Dim document = renderer.RenderHtmlAsPdf("<h1> My First PDF in VB.NET</h1>")
        document.SaveAs("MyFirst.pdf")
    End Sub
End Module
Imports IronPdf
Module Module1
    Sub Main()
        Dim renderer = New ChromePdfRenderer()
        Dim document = renderer.RenderHtmlAsPdf("<h1> My First PDF in VB.NET</h1>")
        document.SaveAs("MyFirst.pdf")
    End Sub
End Module
VB.NET

This sample code snippet first imports the IronPDF namespace, which contains the classes and methods that are 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 PDF new 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

Imports IronPdf
Module Module1
    Sub Main()
        Dim renderer = New ChromePdfRenderer()
        Dim document = renderer.RenderHtmlFileAsPdf("invoice.html")
        document.SaveAs("invoice.pdf")
    End Sub
End Module
Imports IronPdf
Module Module1
    Sub Main()
        Dim renderer = New ChromePdfRenderer()
        Dim document = renderer.RenderHtmlFileAsPdf("invoice.html")
        document.SaveAs("invoice.pdf")
    End Sub
End Module
VB.NET

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.
