IronPDF handles HTML to PDF conversion with ease, its full support for modern web standards ensuring that all of your PDF documents come out pixel-perfect. DocRaptor uses an API-based approach, requiring an API key and cloud-based execution for converting HTML to PDF.

2. Encrypting PDF Files

IronPDF:

using IronPdf;
using System;

// Load an existing PDF with a password
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
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;

// Load an existing PDF with a password
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
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");

DocRaptor: DocRaptor does not natively support PDF encryption features.

IronPDF provides built-in encryption, metadata, and security controls, whereas DocRaptor would require third-party tools to achieve similar functionality.

3. Redacting PDF Content

IronPDF:

using IronPdf;

// Load the PDF and redact specified text
PdfDocument pdf = PdfDocument.FromFile("novel.pdf");
pdf.RedactTextOnAllPages("are");
pdf.SaveAs("redacted.pdf");

using IronPdf;

// Load the PDF and redact specified text
PdfDocument pdf = PdfDocument.FromFile("novel.pdf");
pdf.RedactTextOnAllPages("are");
pdf.SaveAs("redacted.pdf");

DocRaptor does not support redaction functionality.

IronPDF offers native redaction, a critical feature for legal and confidential documents that DocRaptor lacks.

4. Digitally Signing PDF Documents

IronPDF:

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

// Initialize PDF renderer and create a PDF document
ChromePdfRenderer renderer = new ChromePdfRenderer();
PdfDocument pdf = renderer.RenderHtmlAsPdf("<h1>foo</h1>");

// Load the certificate for signing
X509Certificate2 cert = new X509Certificate2("IronSoftware.pfx", "123456", X509KeyStorageFlags.Exportable);

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

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

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

// Initialize PDF renderer and create a PDF document
ChromePdfRenderer renderer = new ChromePdfRenderer();
PdfDocument pdf = renderer.RenderHtmlAsPdf("<h1>foo</h1>");

// Load the certificate for signing
X509Certificate2 cert = new X509Certificate2("IronSoftware.pfx", "123456", X509KeyStorageFlags.Exportable);

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

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

DocRaptor does not natively support PDF signing.

IronPDF provides a built-in mechanism to digitally sign PDFs, making it superior for authentication and legal documents. DocRaptor lacks this key feature, so users of this library will need to download additional libraries to carry out this task.

5. Applying Custom Watermarks

IronPDF:

using IronPdf;

// Stamper to apply a watermark on a 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;

// Stamper to apply a watermark on a 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");

DocRaptor:

using DocRaptor.Client;
using DocRaptor.Model;
using DocRaptor.Api;
using System;
using System.IO;

class DocRaptorExample
{
    static void Main(string[] args)
    {
        DocApi docraptor = new DocApi();
        docraptor.Configuration.Username = "YOUR_API_KEY_HERE";

        try
        {
            Doc doc = new Doc(
                name: "text-based-watermark",
                test: false, // Test documents are free but watermarked
                documentType: Doc.DocumentTypeEnum.Pdf,
                documentContent: System.IO.File.ReadAllText(@"text-based-watermark-content.html") 
            );

            byte[] document = docraptor.CreateDoc(doc);
            File.WriteAllBytes("text-based-watermark.pdf", document);
            Console.WriteLine("Successfully created text-based-watermark.pdf!");
        } catch (DocRaptor.Client.ApiException error) {
            Console.Write(error.ErrorContent);
        }
    }
}

using DocRaptor.Client;
using DocRaptor.Model;
using DocRaptor.Api;
using System;
using System.IO;

class DocRaptorExample
{
    static void Main(string[] args)
    {
        DocApi docraptor = new DocApi();
        docraptor.Configuration.Username = "YOUR_API_KEY_HERE";

        try
        {
            Doc doc = new Doc(
                name: "text-based-watermark",
                test: false, // Test documents are free but watermarked
                documentType: Doc.DocumentTypeEnum.Pdf,
                documentContent: System.IO.File.ReadAllText(@"text-based-watermark-content.html") 
            );

            byte[] document = docraptor.CreateDoc(doc);
            File.WriteAllBytes("text-based-watermark.pdf", document);
            Console.WriteLine("Successfully created text-based-watermark.pdf!");
        } catch (DocRaptor.Client.ApiException error) {
            Console.Write(error.ErrorContent);
        }
    }
}

IronPDF provides full watermarking capabilities, allowing you to create and apply custom watermarks in just a few lines of code, and these watermarks can be applied to new or existing PDF files. DocRaptor, however, requires the watermarks to be added using HTML and CSS before converting the HTML content to PDF.

6. Stamping Text and Images

IronPDF:

using IronPdf;
using IronPdf.Editing;

// Initialize PDF renderer and create a basic HTML-based PDF
ChromePdfRenderer renderer = new ChromePdfRenderer();
PdfDocument pdf = renderer.RenderHtmlAsPdf("<h1>Example HTML Document!</h1>");

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

// Apply the text stamper to the PDF
pdf.ApplyStamp(textStamper);
pdf.SaveAs("stampText.pdf");

using IronPdf;
using IronPdf.Editing;

// Initialize PDF renderer and create a basic HTML-based PDF
ChromePdfRenderer renderer = new ChromePdfRenderer();
PdfDocument pdf = renderer.RenderHtmlAsPdf("<h1>Example HTML Document!</h1>");

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

// Apply the text stamper to the PDF
pdf.ApplyStamp(textStamper);
pdf.SaveAs("stampText.pdf");

DocRaptor lacks a native feature for stamping text and images on PDFs.

IronPDF allows for detailed customization when stamping text and images, making it a superior choice for document annotations and branding. DocRaptor lacks any native support for text and image stamping, with watermarks being the closest thing to this.

7. DOCX to PDF

IronPDF:

using IronPdf;

// Instantiate a renderer specifically for DOCX files
DocxToPdfRenderer renderer = new DocxToPdfRenderer();

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

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

using IronPdf;

// Instantiate a renderer specifically for DOCX files
DocxToPdfRenderer renderer = new DocxToPdfRenderer();

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

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

DocRaptor:

No native support for DOCX to PDF conversion.

IronPDF provides a smoother and more native process for DOCX to PDF conversion, without the need for any external libraries like DocRaptor, who lacks built-in support for this task.

DocRaptor: Good Bootstrap Support with API Complexity

DocRaptor is a cloud-based service that uses the Prince XML rendering engine with good CSS support:

• Bootstrap 4/5 Support: Generally good support for Bootstrap layouts
• Prince XML Engine: Professional-grade HTML/CSS rendering engine
• CSS3 Features: Strong flexbox and modern CSS support
• JavaScript Limitations: Limited JavaScript execution compared to full browsers
• Cloud Dependency: Requires internet connectivity and API calls for all conversions

Key considerations for DocRaptor:

• API-Based: All conversions happen via HTTP API calls to DocRaptor servers
• Internet Required: Cannot generate PDFs offline or in air-gapped environments
• Per-Document Pricing: Unlike IronPDF's per-developer license, DocRaptor charges per document
• Data Privacy: HTML content sent to external servers for processing
• Volume Costs: High-volume applications may incur significant ongoing API costs

Development impact: While DocRaptor handles Bootstrap well, the cloud-based architecture introduces operational considerations:

1. All PDF generation depends on external service availability
2. Per-document costs can escalate quickly with high volume
3. Sensitive content requires evaluation of data handling policies
4. Latency introduced by network round-trips for each conversion

For applications requiring on-premises processing, offline capability, or high-volume document generation, IronPDF's local processing model may offer better long-term value and control.

For Bootstrap framework best practices, see the Bootstrap & Flexbox CSS Guide.
