Features of IronPDF

IronPDF boasts an array of features that cater to the diverse needs of developers working with PDF documents. These features include:

Convert HTML to PDF in C#

IronPDF allows developers to easily convert HTML content, including CSS and JavaScript, to high-quality PDF files. The following code example demonstrates how to create a PDF from an HTML string using C# and no Adobe Acrobat:

using IronPdf;

// Instantiate Renderer
var renderer = new ChromePdfRenderer();

// Create a PDF from an HTML string using C#
var pdf = renderer.RenderHtmlAsPdf("Hello World");

// Export to a file or Stream
pdf.SaveAs("output.pdf");

using IronPdf;

// Instantiate Renderer
var renderer = new ChromePdfRenderer();

// Create a PDF from an HTML string using C#
var pdf = renderer.RenderHtmlAsPdf("Hello World");

// Export to a file or Stream
pdf.SaveAs("output.pdf");

Imports IronPdf

' Instantiate Renderer
Private renderer = New ChromePdfRenderer()

' Create a PDF from an HTML string using C#
Private pdf = renderer.RenderHtmlAsPdf("Hello World")

' Export to a file or Stream
pdf.SaveAs("output.pdf")

Edit PDF

With IronPDF, developers can edit PDF documents, add or remove pages, and manipulate the content within the documents. The following code example demonstrates how to split a PDF document into separate files based on page breaks:

using IronPdf;

// Define multi-page HTML content
const string html = @"Hello Iron
                      This is 1st Page

                      This is 2nd Page

                      This is 3rd Page";

var renderer = new ChromePdfRenderer();
var pdf = renderer.RenderHtmlAsPdf(html);

// Take the first page
var page1doc = pdf.CopyPage(0);
page1doc.SaveAs("Split1.pdf");

// Take the pages 2 & 3
var page23doc = pdf.CopyPages(1, 2);
page23doc.SaveAs("Split2.pdf");

using IronPdf;

// Define multi-page HTML content
const string html = @"Hello Iron
                      This is 1st Page

                      This is 2nd Page

                      This is 3rd Page";

var renderer = new ChromePdfRenderer();
var pdf = renderer.RenderHtmlAsPdf(html);

// Take the first page
var page1doc = pdf.CopyPage(0);
page1doc.SaveAs("Split1.pdf");

// Take the pages 2 & 3
var page23doc = pdf.CopyPages(1, 2);
page23doc.SaveAs("Split2.pdf");

Imports IronPdf

' Define multi-page HTML content
Private Const html As String = "Hello Iron
                      This is 1st Page

                      This is 2nd Page

                      This is 3rd Page"

Private renderer = New ChromePdfRenderer()
Private pdf = renderer.RenderHtmlAsPdf(html)

' Take the first page
Private page1doc = pdf.CopyPage(0)
page1doc.SaveAs("Split1.pdf")

' Take the pages 2 & 3
Dim page23doc = pdf.CopyPages(1, 2)
page23doc.SaveAs("Split2.pdf")

Security of PDF documents

IronPDF offers robust PDF security features, including encryption, password protection, and digital signatures. The following code example demonstrates how to apply encryption and password protection to a PDF document:

using IronPdf;

// Load an existing PDF document
var pdf = PdfDocument.FromFile("input.pdf");

// Set encryption and password protection
pdf.Encrypt(PdfDocument.EncryptionAlgorithm.AES, 256, "ownerPassword", "userPassword");

// Save the encrypted PDF document
pdf.SaveAs("encrypted_output.pdf");

using IronPdf;

// Load an existing PDF document
var pdf = PdfDocument.FromFile("input.pdf");

// Set encryption and password protection
pdf.Encrypt(PdfDocument.EncryptionAlgorithm.AES, 256, "ownerPassword", "userPassword");

// Save the encrypted PDF document
pdf.SaveAs("encrypted_output.pdf");

Imports IronPdf

' Load an existing PDF document
Private pdf = PdfDocument.FromFile("input.pdf")

' Set encryption and password protection
pdf.Encrypt(PdfDocument.EncryptionAlgorithm.AES, 256, "ownerPassword", "userPassword")

' Save the encrypted PDF document
pdf.SaveAs("encrypted_output.pdf")

PDF Metadata

IronPDF enables developers to edit and manage the metadata of PDF documents, such as author, keywords, and modified date. The following code example demonstrates how to modify the metadata of an existing PDF:

using IronPdf;

// Open an Encrypted File, alternatively create a new PDF from HTML
var pdf = PdfDocument.FromFile("encrypted.pdf", "password");

// Edit file metadata
pdf.MetaData.Author = "Satoshi Nakamoto";
pdf.MetaData.Keywords = "SEO, Friendly";
pdf.MetaData.ModifiedDate = System.DateTime.Now;

using IronPdf;

// Open an Encrypted File, alternatively create a new PDF from HTML
var pdf = PdfDocument.FromFile("encrypted.pdf", "password");

// Edit file metadata
pdf.MetaData.Author = "Satoshi Nakamoto";
pdf.MetaData.Keywords = "SEO, Friendly";
pdf.MetaData.ModifiedDate = System.DateTime.Now;

Imports System
Imports IronPdf

' Open an Encrypted File, alternatively create a new PDF from HTML
Private pdf = PdfDocument.FromFile("encrypted.pdf", "password")

' Edit file metadata
pdf.MetaData.Author = "Satoshi Nakamoto"
pdf.MetaData.Keywords = "SEO, Friendly"
pdf.MetaData.ModifiedDate = DateTime.Now

Watermark

IronPDF allows developers to add watermarks to their PDF documents for security and branding. The following code example demonstrates how to stamp a watermark onto a new or existing PDF:

using IronPdf;

// Stamps a Watermark onto a new or existing PDF
var renderer = new ChromePdfRenderer();

var pdf = renderer.RenderUrlAsPdf("https://www.nuget.org/packages/IronPdf");
pdf.ApplyWatermark("SAMPLE", 30, IronPdf.Editing.VerticalAlignment.Middle, IronPdf.Editing.HorizontalAlignment.Center);
pdf.SaveAs(@"C:\Path\To\Watermarked.pdf");

using IronPdf;

// Stamps a Watermark onto a new or existing PDF
var renderer = new ChromePdfRenderer();

var pdf = renderer.RenderUrlAsPdf("https://www.nuget.org/packages/IronPdf");
pdf.ApplyWatermark("SAMPLE", 30, IronPdf.Editing.VerticalAlignment.Middle, IronPdf.Editing.HorizontalAlignment.Center);
pdf.SaveAs(@"C:\Path\To\Watermarked.pdf");

Imports IronPdf

' Stamps a Watermark onto a new or existing PDF
Private renderer = New ChromePdfRenderer()

Private pdf = renderer.RenderUrlAsPdf("https://www.nuget.org/packages/IronPdf")
pdf.ApplyWatermark("SAMPLE", 30, IronPdf.Editing.VerticalAlignment.Middle, IronPdf.Editing.HorizontalAlignment.Center)
pdf.SaveAs("C:\Path\To\Watermarked.pdf")
