IronPDF: .NET PDF Library

IronPDF is a .NET PDF library that makes it simple for C# and VB developers to create, edit, and manipulate PDF documents within .NET applications. IronPDF provides excellent rendering capabilities with support for converting HTML to PDF using IronPDF, converting URLs to PDF using IronPDF, SVG to Image, HTML File to PDF, and much more. IronPDF excels at producing PDFs of reports, invoices, statements, and receipts from web pages or existing HTML/CSS templates.

One critical feature is that the IronPDF library can be used to fill out existing PDF forms or create new PDF forms from scratch. This allows businesses to streamline their document workflow by automating the creation and filling out of forms with IronPDF. In addition, IronPDF makes it easy to add headers and footers using IronPDF, apply watermarks to PDFs with IronPDF, and page numbers to PDF files. This makes it an ideal solution for creating professional-looking PDFs. Let's see how to use IronPDF to convert a PowerPoint presentation to a PDF document.

There are some prerequisites to converting a .ppt file to a PDF document.

1. Visual Studio 2022 (Recommended)

Let's move to the main steps in converting .ppt files to PDFs.

Step 1: Export your PowerPoint Presentation as HTML

Let's use the Package Manager Console method to install IronPDF.

Go to "Tools" in the toolbar and select the "Package Manager Console" option from the side menu.

NuGet Package Manager is shown in Visual Studio

Enter the following command in the console to install IronPDF.

Install-Package IronPPT

Installation of IronPDF Library

Now, it's time to write the code to convert a PowerPoint to PDF using the IronPDF library.

Step 3: Convert the HTML File to PDF

Once the HTML file is available, IronPDF will be used to convert the HTML file to a PDF file.

using IronPdf;

using IronPdf;

Imports IronPdf

var renderer = new ChromePdfRenderer();

var renderer = new ChromePdfRenderer();

Dim renderer = New ChromePdfRenderer()

var pdf = renderer.RenderHtmlFileAsPdf(@"C:\Presentation\Presentation.html");

var pdf = renderer.RenderHtmlFileAsPdf(@"C:\Presentation\Presentation.html");

Dim pdf = renderer.RenderHtmlFileAsPdf("C:\Presentation\Presentation.html")

Step 4: Add watermark, password, and headers in the PDF file

pdf.ApplyStamp(new ImageStamper("https://ironpdf.com/img/products/ironpdf-logo-text-dotnet.svg"));

pdf.ApplyStamp(new ImageStamper("https://ironpdf.com/img/products/ironpdf-logo-text-dotnet.svg"));

pdf.ApplyStamp(New ImageStamper("https://ironpdf.com/img/products/ironpdf-logo-text-dotnet.svg"))

pdf.Password = "EasyPassword";

pdf.Password = "EasyPassword";

pdf.Password = "EasyPassword"

renderer.RenderingOptions.HtmlHeader = new HtmlHeaderFooter()
{
    MaxHeight = 20, //millimeters
    HtmlFragment = "<h1>Headers are easy with IronPDF!</h1>",
};

renderer.RenderingOptions.HtmlHeader = new HtmlHeaderFooter()
{
    MaxHeight = 20, //millimeters
    HtmlFragment = "<h1>Headers are easy with IronPDF!</h1>",
};

renderer.RenderingOptions.HtmlHeader = New HtmlHeaderFooter() With {
	.MaxHeight = 20,
	.HtmlFragment = "<h1>Headers are easy with IronPDF!</h1>"
}

Step 5: Save PDF File

After all customizations are done, it's now time to save the PDF file on the local machine. Use IronPDF's SaveAs method to save the PDF file.

pdf.SaveAs("C:\\PptToPdf.pdf");

pdf.SaveAs("C:\\PptToPdf.pdf");

pdf.SaveAs("C:\PptToPdf.pdf")

Let's look at the Program.cs file.

using IronPdf;
using IronPdf.Editing;

var renderer = new ChromePdfRenderer();
renderer.RenderingOptions.HtmlHeader = new HtmlHeaderFooter()
{
    MaxHeight = 20, //millimeters
    HtmlFragment = "<h1>Headers are easy with IronPDF!</h1>",
};

var pdf = renderer.RenderHtmlFileAsPdf(@"C:\Presentation\Presentation.html");

pdf.ApplyStamp(new ImageStamper("https://ironpdf.com/img/products/ironpdf-logo-text-dotnet.svg"));

pdf.Password = "EasyPassword";

pdf.SaveAs("C:\\PptToPdf.pdf");

using IronPdf;
using IronPdf.Editing;

var renderer = new ChromePdfRenderer();
renderer.RenderingOptions.HtmlHeader = new HtmlHeaderFooter()
{
    MaxHeight = 20, //millimeters
    HtmlFragment = "<h1>Headers are easy with IronPDF!</h1>",
};

var pdf = renderer.RenderHtmlFileAsPdf(@"C:\Presentation\Presentation.html");

pdf.ApplyStamp(new ImageStamper("https://ironpdf.com/img/products/ironpdf-logo-text-dotnet.svg"));

pdf.Password = "EasyPassword";

pdf.SaveAs("C:\\PptToPdf.pdf");

Imports IronPdf
Imports IronPdf.Editing

Private renderer = New ChromePdfRenderer()
renderer.RenderingOptions.HtmlHeader = New HtmlHeaderFooter() With {
	.MaxHeight = 20,
	.HtmlFragment = "<h1>Headers are easy with IronPDF!</h1>"
}

Dim pdf = renderer.RenderHtmlFileAsPdf("C:\Presentation\Presentation.html")

pdf.ApplyStamp(New ImageStamper("https://ironpdf.com/img/products/ironpdf-logo-text-dotnet.svg"))

pdf.Password = "EasyPassword"

pdf.SaveAs("C:\PptToPdf.pdf")
