// Disable local disk access or cross-origin requests
Installation.EnableWebSecurity = true;

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

// Create a PDF from an HTML string using C#
var pdf = renderer.RenderHtmlAsPdf("<h1>Hello World</h1>");

myAdvancedPdf.SaveAs("html-with-assets.pdf");

using IronPdf;

// Disable local disk access or cross-origin requests
Installation.EnableWebSecurity = true;

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

// Create a PDF from an HTML string using C#
var pdf = renderer.RenderHtmlAsPdf("<h1>Hello World</h1>");

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

// Advanced Example with HTML Assets
// Load external html assets: Images, CSS and JavaScript.
// An optional BasePath 'C:\\site\\assets\\' is set as the file location to load assets from
var myAdvancedPdf = renderer.RenderHtmlAsPdf("<img src='icons/iron.png'>", @"C:\site\assets\");
myAdvancedPdf.SaveAs("html-with-assets.pdf");

WkHtmlToPdf (Using DinkToPdf):

using DinkToPdf;
var converter = new BasicConverter(new PdfTools());
var doc = new HtmlToPdfDocument()
{
    Objects = { new ObjectSettings() { HtmlContent = "<h1>Hello World</h1>" } }
};
byte[] pdf = converter.Convert(doc);
System.IO.File.WriteAllBytes("HtmlToPdf.pdf", pdf);

using DinkToPdf;
var converter = new BasicConverter(new PdfTools());
var doc = new HtmlToPdfDocument()
{
    Objects = { new ObjectSettings() { HtmlContent = "<h1>Hello World</h1>" } }
};
byte[] pdf = converter.Convert(doc);
System.IO.File.WriteAllBytes("HtmlToPdf.pdf", pdf);

WkHtmlToPdf (Using command line)

wkhtmltopdf myfile.html myfile.pdf

wkhtmltopdf myfile.html myfile.pdf

With IronPDF, you can create pixel-perfect PDF files from HTML content in just a few lines of code! Its support for modern web standards ensures the PDF file you produce retains as much of the original source's quality as possible. WkHtmlToPdf is built around HTML to PDF conversion, and its simplistic way of tackling this task, whether as part of another library or within a command line tool, just goes to show this.

Encrypting PDF Files

IronPDF:

using IronPdf;
using System;

// 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 = DateTime.Now;

// Edit file security settings
// The following code makes a PDF read-only and will disallow copy & paste and printing
pdf.SecuritySettings.RemovePasswordsAndEncryption();
pdf.SecuritySettings.MakePdfDocumentReadOnly("secret-key");
pdf.SecuritySettings.AllowUserAnnotations = false;
pdf.SecuritySettings.AllowUserCopyPasteContent = false;
pdf.SecuritySettings.AllowUserFormData = false;
pdf.SecuritySettings.AllowUserPrinting = IronPdf.Security.PdfPrintSecurity.FullPrintRights;

// Change or set the document encryption password
pdf.Password = "my-password";
pdf.SaveAs("secured.pdf");

using IronPdf;
using System;

// 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 = DateTime.Now;

// Edit file security settings
// The following code makes a PDF read-only and will disallow copy & paste and printing
pdf.SecuritySettings.RemovePasswordsAndEncryption();
pdf.SecuritySettings.MakePdfDocumentReadOnly("secret-key");
pdf.SecuritySettings.AllowUserAnnotations = false;
pdf.SecuritySettings.AllowUserCopyPasteContent = false;
pdf.SecuritySettings.AllowUserFormData = false;
pdf.SecuritySettings.AllowUserPrinting = IronPdf.Security.PdfPrintSecurity.FullPrintRights;

// Change or set the document encryption password
pdf.Password = "my-password";
pdf.SaveAs("secured.pdf");

WkHtmlToPdf:

Encryption support is not directly provided by WkHtmlToPdf without third-party libraries.

IronPDF provides a straightforward, easy-to-implement method for encrypting PDF files, while giving you plenty of control of the entire process. WkHtmlToPdf, due to it being more of HTML to PDF conversion focused tool, doesn't offer any direct support for PDF encryption on its own.

Redacting PDF Content

IronPDF:

using IronPdf;

PdfDocument pdf = PdfDocument.FromFile("novel.pdf");

// Redact 'are' phrase from all pages
pdf.RedactTextOnAllPages("are");

pdf.SaveAs("redacted.pdf");

using IronPdf;

PdfDocument pdf = PdfDocument.FromFile("novel.pdf");

// Redact 'are' phrase from all pages
pdf.RedactTextOnAllPages("are");

pdf.SaveAs("redacted.pdf");

WkHtmlToPdf:

WkHtmlToPdf lacks built-in redaction features.

IronPDF's redaction feature is a powerful, concise API that makes it easy to redact specified content in just a few lines of code, making the automation of your redaction tasks easy. WkHtmlToPdf does not offer any built-in support for PDF redaction.

Digitally Signing PDF Files

IronPDF:

using IronPdf;
using IronPdf.Signing;
using System.Security.Cryptography.X509Certificates;

// Instantiate Renderer
ChromePdfRenderer renderer = new ChromePdfRenderer();
PdfDocument pdf = renderer.RenderHtmlAsPdf("<h1>foo</h1>");

// Create X509Certificate2 object with X509KeyStorageFlags set to Exportable
X509Certificate2 cert = new X509Certificate2("IronSoftware.pfx", "123456", X509KeyStorageFlags.Exportable);

// Create PdfSignature object
var sig = new PdfSignature(cert);

// Sign PDF document
pdf.Sign(sig);
pdf.SaveAs("signed.pdf");

using IronPdf;
using IronPdf.Signing;
using System.Security.Cryptography.X509Certificates;

// Instantiate Renderer
ChromePdfRenderer renderer = new ChromePdfRenderer();
PdfDocument pdf = renderer.RenderHtmlAsPdf("<h1>foo</h1>");

// Create X509Certificate2 object with X509KeyStorageFlags set to Exportable
X509Certificate2 cert = new X509Certificate2("IronSoftware.pfx", "123456", X509KeyStorageFlags.Exportable);

// Create PdfSignature object
var sig = new PdfSignature(cert);

// Sign PDF document
pdf.Sign(sig);
pdf.SaveAs("signed.pdf");

WkHtmlToPdf C#:

WkHtmlToPdf C# does not offer native support for signing PDFs.

When you're using IronPDF, it's easy to digitally sign your PDF thanks to its easy-to-use digital signature feature. This powerful signing tool gives you the tools you need to start digitally signing PDF files programmatically, saving you time if you find yourself signing PDF files regularly. With WkHtmlToPdf, it in itself cannot handle PDF signing, however, if you're using it as a part of another library, that library may have the capabilities to carry out this task.

Applying Custom Watermarks to your PDF

IronPDF:

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("<h2 style='color:red'>SAMPLE</h2>", 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("<h2 style='color:red'>SAMPLE</h2>", 30, IronPdf.Editing.VerticalAlignment.Middle, IronPdf.Editing.HorizontalAlignment.Center);
pdf.SaveAs(@"C:\Path\To\Watermarked.pdf");

WkHtmlToPdf:

Does not have a direct, clear method for this. Instead, you would need to implement advanced CSS styling in order to apply watermarks or use a separate PDF library that can handle it.

IronPDF provides users with a strong, concise watermarking tool. With an approach similar to HTML/CSS, IronPDF's watermarking tool is easy to use and makes applying your custom watermarks to PDF files a breeze. If you're using WkHtmlToPdf by itself, watermarking is only possible with the use of CSS.

Stamping Images and Text

IronPDF:

using IronPdf;
using IronPdf.Editing;

ChromePdfRenderer renderer = new ChromePdfRenderer();
PdfDocument pdf = renderer.RenderHtmlAsPdf("<h1>Example HTML Document!</h1>");

// Create text stamper
TextStamper textStamper = new TextStamper()
{
    Text = "Text Stamper!",
    FontFamily = "Bungee Spice",
    UseGoogleFont = true,
    FontSize = 30,
    IsBold = true,
    IsItalic = true,
    VerticalAlignment = VerticalAlignment.Top,
};

// Stamp the text stamper
pdf.ApplyStamp(textStamper);
pdf.SaveAs("stampText.pdf");

using IronPdf;
using IronPdf.Editing;

ChromePdfRenderer renderer = new ChromePdfRenderer();
PdfDocument pdf = renderer.RenderHtmlAsPdf("<h1>Example HTML Document!</h1>");

// Create text stamper
TextStamper textStamper = new TextStamper()
{
    Text = "Text Stamper!",
    FontFamily = "Bungee Spice",
    UseGoogleFont = true,
    FontSize = 30,
    IsBold = true,
    IsItalic = true,
    VerticalAlignment = VerticalAlignment.Top,
};

// Stamp the text stamper
pdf.ApplyStamp(textStamper);
pdf.SaveAs("stampText.pdf");

using IronPdf;
using IronPdf.Editing;
using System;

ChromePdfRenderer renderer = new ChromePdfRenderer();
PdfDocument pdf = renderer.RenderHtmlAsPdf("<h1>Example HTML Document!</h1>");

// Create image stamper
ImageStamper imageStamper = new ImageStamper(new Uri("https://ironpdf.com/img/svgs/iron-pdf-logo.svg"))
{
    VerticalAlignment = VerticalAlignment.Top,
};

// Stamp the image stamper
pdf.ApplyStamp(imageStamper, 0);
pdf.SaveAs("stampImage.pdf");

using IronPdf;
using IronPdf.Editing;
using System;

ChromePdfRenderer renderer = new ChromePdfRenderer();
PdfDocument pdf = renderer.RenderHtmlAsPdf("<h1>Example HTML Document!</h1>");

// Create image stamper
ImageStamper imageStamper = new ImageStamper(new Uri("https://ironpdf.com/img/svgs/iron-pdf-logo.svg"))
{
    VerticalAlignment = VerticalAlignment.Top,
};

// Stamp the image stamper
pdf.ApplyStamp(imageStamper, 0);
pdf.SaveAs("stampImage.pdf");

WkHtmlToPdf C#:

Stamping text and images requires an indirect approach using HTML and CSS, as it does not have any built-in options specifically for this.

With IronPDF, Stamping Text and Images onto your PDF files has never been easier thanks to its powerful, easy-to-use image and text stamping tools. WkHtmlToPdf doesn't contain any built-in stamping tools, but you can still achieve a similar result by using HTML and CSS to apply the stamped content.

DOCX to PDF Conversion

IronPDF:

using IronPdf;

// Instantiate Renderer
DocxToPdfRenderer renderer = new DocxToPdfRenderer();

// Render from DOCX file
PdfDocument pdf = renderer.RenderDocxAsPdf("Modern-chronological-resume.docx");

// Save the PDF
pdf.SaveAs("pdfFromDocx.pdf");

using IronPdf;

// Instantiate Renderer
DocxToPdfRenderer renderer = new DocxToPdfRenderer();

// Render from DOCX file
PdfDocument pdf = renderer.RenderDocxAsPdf("Modern-chronological-resume.docx");

// Save the PDF
pdf.SaveAs("pdfFromDocx.pdf");

WkHtmlToPdf C#:

Requires additional libraries to handle DOCX to PDF conversions.

IronPDF simplifies DOCX to PDF conversion with its powerful DOCX to PDF tool, while taking only a few lines of code, ultimately raising the efficiency of your projects. WkHtmlToPdf doesn't offer any built-in DOCX to PDF conversion support; instead, you would need to look into other PDF libraries that can handle it.
