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>");
pdf.SaveAs("output.pdf");
// Advanced example with HTML assets
// Load external HTML assets: images, CSS, and JavaScript
var myAdvancedPdf = renderer.RenderHtmlAsPdf("<img src='icons/iron.png'>", @"C:\site\assets\");
myAdvancedPdf.SaveAs("html-with-assets.pdf");
using IronPdf;
// Enable web security to prevent 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>");
pdf.SaveAs("output.pdf");
// Advanced example with HTML assets
// Load external HTML assets: images, CSS, and JavaScript
var myAdvancedPdf = renderer.RenderHtmlAsPdf("<img src='icons/iron.png'>", @"C:\site\assets\");
myAdvancedPdf.SaveAs("html-with-assets.pdf");
Imports IronPdf
' Enable web security to prevent local disk access or cross-origin requests
Installation.EnableWebSecurity = True
' Instantiate Renderer
Dim renderer = New ChromePdfRenderer()
' Create a PDF from an HTML string using C#
Dim pdf = renderer.RenderHtmlAsPdf("<h1>Hello World</h1>")
pdf.SaveAs("output.pdf")
' Advanced example with HTML assets
' Load external HTML assets: images, CSS, and JavaScript
Dim myAdvancedPdf = renderer.RenderHtmlAsPdf("<img src='icons/iron.png'>", "C:\site\assets\")
myAdvancedPdf.SaveAs("html-with-assets.pdf")
Aspose.PDF:
using Aspose.Pdf;
using Aspose.Pdf.Text;
Document doc = new Document();
Page page = doc.Pages.Add();
HtmlFragment text = new HtmlFragment("<h1>Hello World</h1>");
page.Paragraphs.Add(text);
doc.Save("output.pdf");
using Aspose.Pdf;
using Aspose.Pdf.Text;
Document doc = new Document();
Page page = doc.Pages.Add();
HtmlFragment text = new HtmlFragment("<h1>Hello World</h1>");
page.Paragraphs.Add(text);
doc.Save("output.pdf");
Imports Aspose.Pdf
Imports Aspose.Pdf.Text
Private doc As New Document()
Private page As Page = doc.Pages.Add()
Private text As New HtmlFragment("<h1>Hello World</h1>")
page.Paragraphs.Add(text)
doc.Save("output.pdf")
IronPDF offers users a streamlined and concise method for converting HTML content to PDF files, made easy by its excellent support of modern web standards. Aspose.PDF offers a robust API capable of handling HTML to PDF conversion; however, the process may be considered less straightforward, requiring more steps.
The ability to encrypt and decrypt PDF documents can be essential in any environment dealing with sensitive information or private data. Below, we compare how the two products handle encrypting PDFs.
IronPDF:
using IronPdf;
using System;
// Open an encrypted file or 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
// Prevent copy-paste and printing by making the PDF read-only
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;
// Set or change the document encryption password
pdf.Password = "my-password";
pdf.SaveAs("secured.pdf");
using IronPdf;
using System;
// Open an encrypted file or 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
// Prevent copy-paste and printing by making the PDF read-only
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;
// Set or change the document encryption password
pdf.Password = "my-password";
pdf.SaveAs("secured.pdf");
Imports IronPdf
Imports System
' Open an encrypted file or 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
' Edit file security settings
' Prevent copy-paste and printing by making the PDF read-only
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
' Set or change the document encryption password
pdf.Password = "my-password"
pdf.SaveAs("secured.pdf")
Aspose.PDF:
using Aspose.Pdf;
Document pdfDocument = new Document("document.pdf");
pdfDocument.Encrypt("password", null, Permissions.PrintDocument, CryptoAlgorithm.AESx128);
pdfDocument.Save("encrypted.pdf");
using Aspose.Pdf;
Document pdfDocument = new Document("document.pdf");
pdfDocument.Encrypt("password", null, Permissions.PrintDocument, CryptoAlgorithm.AESx128);
pdfDocument.Save("encrypted.pdf");
Imports Aspose.Pdf
Private pdfDocument As New Document("document.pdf")
pdfDocument.Encrypt("password", Nothing, Permissions.PrintDocument, CryptoAlgorithm.AESx128)
pdfDocument.Save("encrypted.pdf")
While both libraries offer robust encryption tools, IronPDF presents a straightforward encryption process while also providing more control over the security settings of the PDF file. Aspose.PDF's encryption process is similarly concise and straightforward; however, it lacks the same ease of control over various settings.
When you need to redact certain parts of a PDF document, it's essential to know how different libraries handle the process. Below, we compare how IronPDF and Aspose.PDF perform redactions.
IronPDF:
using IronPdf;
// Load the document you want to redact
PdfDocument pdf = PdfDocument.FromFile("novel.pdf");
// Redact the 'are' phrase from all pages
pdf.RedactTextOnAllPages("are");
// Save the redacted version of the document
pdf.SaveAs("redacted.pdf");
using IronPdf;
// Load the document you want to redact
PdfDocument pdf = PdfDocument.FromFile("novel.pdf");
// Redact the 'are' phrase from all pages
pdf.RedactTextOnAllPages("are");
// Save the redacted version of the document
pdf.SaveAs("redacted.pdf");
Imports IronPdf
' Load the document you want to redact
Private pdf As PdfDocument = PdfDocument.FromFile("novel.pdf")
' Redact the 'are' phrase from all pages
pdf.RedactTextOnAllPages("are")
' Save the redacted version of the document
pdf.SaveAs("redacted.pdf")
Aspose.PDF:
using Aspose.Pdf;
using Aspose.Pdf.Redaction;
Document document = new Document("novel.pdf");
TextFragmentAbsorber textFragmentAbsorber = new TextFragmentAbsorber("confidential");
document.Pages.Accept(textFragmentAbsorber);
foreach (TextFragment textFragment in textFragmentAbsorber.TextFragments)
{
textFragment.Text = "XXXXX";
}
document.Save("redacted.pdf");
using Aspose.Pdf;
using Aspose.Pdf.Redaction;
Document document = new Document("novel.pdf");
TextFragmentAbsorber textFragmentAbsorber = new TextFragmentAbsorber("confidential");
document.Pages.Accept(textFragmentAbsorber);
foreach (TextFragment textFragment in textFragmentAbsorber.TextFragments)
{
textFragment.Text = "XXXXX";
}
document.Save("redacted.pdf");
Imports Aspose.Pdf
Imports Aspose.Pdf.Redaction
Private document As New Document("novel.pdf")
Private textFragmentAbsorber As New TextFragmentAbsorber("confidential")
document.Pages.Accept(textFragmentAbsorber)
For Each textFragment As TextFragment In textFragmentAbsorber.TextFragments
textFragment.Text = "XXXXX"
Next textFragment
document.Save("redacted.pdf")
When it comes to redacting PDF content, IronPDF offers a direct approach. Its straightforward and intuitive API makes it easy for users to redact content programmatically, increasing workspace efficiency. Aspose.PDF can achieve similar results, but the process is more manual. If you wanted to draw black boxes over text like IronPDF does, the process becomes even more complex.
Digitally signing PDF documents programmatically can save a lot of time. The code examples below compare the signing process in IronPDF and Aspose.PDF.
IronPDF:
using IronPdf;
using IronPdf.Signing;
using System.Security.Cryptography.X509Certificates;
// 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
PdfDocument pdf = PdfDocument.FromFile("document.pdf");
pdf.Sign(sig);
pdf.SaveAs("signed.pdf");
using IronPdf;
using IronPdf.Signing;
using System.Security.Cryptography.X509Certificates;
// 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
PdfDocument pdf = PdfDocument.FromFile("document.pdf");
pdf.Sign(sig);
pdf.SaveAs("signed.pdf");
Imports IronPdf
Imports IronPdf.Signing
Imports System.Security.Cryptography.X509Certificates
' Create X509Certificate2 object with X509KeyStorageFlags set to Exportable
Private cert As New X509Certificate2("IronSoftware.pfx", "123456", X509KeyStorageFlags.Exportable)
' Create PdfSignature object
Private sig = New PdfSignature(cert)
' Sign PDF document
Private pdf As PdfDocument = PdfDocument.FromFile("document.pdf")
pdf.Sign(sig)
pdf.SaveAs("signed.pdf")
Aspose.PDF:
using Aspose.Pdf;
using Aspose.Pdf.Forms;
using Aspose.Pdf.Facades;
Document document = new Document("input.pdf");
PKCS7 pkcs = new PKCS7("signature.pfx", "password");
Document.SignatureField signatureField = new SignatureField(document.Pages[1], new Rectangle(100, 100, 200, 200));
document.Form.Add(signatureField);
document.Save("signed.pdf");
using Aspose.Pdf;
using Aspose.Pdf.Forms;
using Aspose.Pdf.Facades;
Document document = new Document("input.pdf");
PKCS7 pkcs = new PKCS7("signature.pfx", "password");
Document.SignatureField signatureField = new SignatureField(document.Pages[1], new Rectangle(100, 100, 200, 200));
document.Form.Add(signatureField);
document.Save("signed.pdf");
Imports Aspose.Pdf
Imports Aspose.Pdf.Forms
Imports Aspose.Pdf.Facades
Private document As New Document("input.pdf")
Private pkcs As New PKCS7("signature.pfx", "password")
Private signatureField As Document.SignatureField = New SignatureField(document.Pages(1), New Rectangle(100, 100, 200, 200))
document.Form.Add(signatureField)
document.Save("signed.pdf")
IronPDF offers a simple and straightforward process for signing PDF documents, requiring fewer lines of code and making the process quick and easy. Aspose.PDF has a longer approach to the process, requiring more lines of code but allowing users more control over the process.
Adding and customizing watermarks on your PDF documents programmatically can be useful, especially when dealing with confidential files, branding, ensuring copyright protection, and so on. Now, we compare how IronPDF and Aspose.PDF handle adding watermarks to a PDF document.
IronPDF:
using IronPdf;
// Stamp 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;
// Stamp 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");
Imports IronPdf
' Stamp a watermark onto a new or existing PDF
Private renderer = New ChromePdfRenderer()
Private 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")
Aspose.PDF:
using Aspose.Pdf;
using Aspose.Pdf.Text;
Document document = new Document("input.pdf");
TextStamp textStamp = new TextStamp("Confidential");
textStamp.Background = true;
textStamp.Opacity = 0.5;
document.Pages[1].AddStamp(textStamp);
document.Save("watermarked.pdf");
using Aspose.Pdf;
using Aspose.Pdf.Text;
Document document = new Document("input.pdf");
TextStamp textStamp = new TextStamp("Confidential");
textStamp.Background = true;
textStamp.Opacity = 0.5;
document.Pages[1].AddStamp(textStamp);
document.Save("watermarked.pdf");
Imports Aspose.Pdf
Imports Aspose.Pdf.Text
Private document As New Document("input.pdf")
Private textStamp As New TextStamp("Confidential")
textStamp.Background = True
textStamp.Opacity = 0.5
document.Pages(1).AddStamp(textStamp)
document.Save("watermarked.pdf")
IronPDF's simple and effective API allows users to quickly apply watermarks to their PDF documents with more control due to its use of HTML/CSS. This makes it easy for users to apply custom watermarks tailored to their needs. Aspose.PDF lacks a native watermark tool, using the TextStamp method instead. While this achieves similar results, it offers less control over the process.
Just as with applying watermarks, stamping content onto PDF pages can be essential in certain workflows. Here, we compare how IronPDF and Aspose.PDF handle stamping content.

' Stamp the image on the PDF
pdf.ApplyStamp(imageStamper, 0)
pdf.SaveAs("stampImage.pdf")
Aspose.PDF:
using Aspose.Pdf;
using Aspose.Pdf.Text;
Document document = new Document("input.pdf");
ImageStamp imageStamp = new ImageStamp("logo.png");
imageStamp.Background = true; // Enable background for the stamp
document.Pages[1].AddStamp(imageStamp);

document.Save("stamped.pdf")
When stamping text and images onto PDF documents, IronPDF offers great flexibility and customization, giving users full control over the process. Its API is straightforward and easy to use, especially for users who may be familiar with HTML/CSS. Aspose.PDF has less customization and flexibility, maintaining a straightforward approach to stamping, albeit with less intuitive feel and control that IronPDF offers.
Converting various file types to PDF can be essential. For this example, we will look specifically at converting a DOCX file to PDF.
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");
Imports IronPdf
' Instantiate Renderer
Private renderer As New DocxToPdfRenderer()
' Render from DOCX file
Private pdf As PdfDocument = renderer.RenderDocxAsPdf("Modern-chronological-resume.docx")
' Save the PDF
pdf.SaveAs("pdfFromDocx.pdf")
Aspose.PDF:
using Aspose.Words;
using Aspose.Words.Saving;
Document doc = new Document("input.docx");
doc.Save("output.pdf", SaveFormat.Pdf);
using Aspose.Words;
using Aspose.Words.Saving;
Document doc = new Document("input.docx");
doc.Save("output.pdf", SaveFormat.Pdf);
Imports Aspose.Words
Imports Aspose.Words.Saving
Private doc As New Document("input.docx")
doc.Save("output.pdf", SaveFormat.Pdf)
IronPDF offers a simplistic and direct approach to DOCX to PDF conversion, leveraging ChromePdfRenderer to generate high-fidelity PDFs from DOCX files. This is built into the IronPDF library, requiring no additional packages.
