加密 PDF 文件

IronPDF 示例：

using IronPdf;
using System;

// Open an encrypted file or 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

// Make the PDF read-only, disallow copying & pasting, and disallow 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 or 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

// Make the PDF read-only, disallow copying & pasting, and disallow 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");

Imports IronPdf
Imports System

' Open an encrypted file or 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

' Make the PDF read-only, disallow copying & pasting, and disallow 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")

NReco.PdfGenerator Example: NReco.PdfGenerator does not natively support PDF encryption, as the focus of this library is primarily on handling HTML to PDF conversion.

IronPDF offers a straightforward yet powerful tool for encrypting PDFs. With IronPDF, you will have full control over the entire process, including setting security settings. NReco.PdfGenerator, however, lacks native encryption features, so if you want to encrypt your PDF file after using NReco.PdfGenerator to convert it, you will need additional libraries that can handle PDF encryption.

編輯 PDF 內容

IronPDF 示例：

using IronPdf;

// Load the PDF document
PdfDocument pdf = PdfDocument.FromFile("novel.pdf");

// Redact the word 'are' on all pages of the document
pdf.RedactTextOnAllPages("are");

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

using IronPdf;

// Load the PDF document
PdfDocument pdf = PdfDocument.FromFile("novel.pdf");

// Redact the word 'are' on all pages of the document
pdf.RedactTextOnAllPages("are");

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

Imports IronPdf

' Load the PDF document
Private pdf As PdfDocument = PdfDocument.FromFile("novel.pdf")

' Redact the word 'are' on all pages of the document
pdf.RedactTextOnAllPages("are")

' Save the redacted PDF
pdf.SaveAs("redacted.pdf")

NReco.PdfGenerator Example: NReco.PdfGenerator does not natively support text redaction.

Requiring just a few lines of code, IronPDF provides you with a concise and easy-to-use redaction tool. Given its simplicity, you can be sure that by using IronPDF's redaction feature, you will be able to increase the efficiency of your workspace right off the bat. NReco.PdfGenerator, on the other hand, would require an additional external library to handle the redaction process as it has no native support for PDF redaction.

For more redaction examples, visit the IronPDF How-To guide on this topic.

ChromePdfRenderer renderer = new ChromePdfRenderer();

// Render HTML as PDF
PdfDocument pdf = renderer.RenderHtmlAsPdf("<h1>foo</h1>");

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

// Create PdfSignature object and sign the PDF document
var sig = new PdfSignature(cert);
pdf.Sign(sig);

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

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

// Instantiate the Chrome PDF Renderer
ChromePdfRenderer renderer = new ChromePdfRenderer();

// Render HTML as PDF
PdfDocument pdf = renderer.RenderHtmlAsPdf("<h1>foo</h1>");

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

// Create PdfSignature object and sign the PDF document
var sig = new PdfSignature(cert);
pdf.Sign(sig);

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

Imports IronPdf
Imports IronPdf.Signing
Imports System.Security.Cryptography.X509Certificates

' Instantiate the Chrome PDF Renderer

Private cert As New X509Certificate2("IronSoftware.pfx", "123456", X509KeyStorageFlags.Exportable)

' Create PdfSignature object and sign the PDF document
Private sig = New PdfSignature(cert)
pdf.Sign(sig)

' Save the signed PDF
pdf.SaveAs("signed.pdf")

NReco.PdfGenerator Example: NReco.PdfGenerator does not natively support digital signatures.

IronPDF's digital signature feature provides you with an easy way to automate the signing of PDFs. Its straightforward API gives you full control over the signing process, while its ease of implementation means less work for you if you find yourself signing PDFs regularly.

NReco.PdfGenerator does not offer any support for digitally signing PDFs, but you can make use of third-party libraries such as iTextSharp to do this.

// Apply an HTML-based watermark to the PDF
pdf.ApplyWatermark("<h2 style='color:red'>SAMPLE</h2>", 30, IronPdf.Editing.VerticalAlignment.Middle, IronPdf.Editing.HorizontalAlignment.Center);

// Save the watermarked PDF
pdf.SaveAs(@"C:\Path\To\Watermarked.pdf");

using IronPdf;

// Instantiate the renderer and render a PDF from a URL
var renderer = new ChromePdfRenderer();
var pdf = renderer.RenderUrlAsPdf("https://www.nuget.org/packages/IronPdf");

// Apply an HTML-based watermark to the PDF
pdf.ApplyWatermark("<h2 style='color:red'>SAMPLE</h2>", 30, IronPdf.Editing.VerticalAlignment.Middle, IronPdf.Editing.HorizontalAlignment.Center);

// Save the watermarked PDF
pdf.SaveAs(@"C:\Path\To\Watermarked.pdf");

Imports IronPdf

' Instantiate the renderer and render a PDF from a URL
Private renderer = New ChromePdfRenderer()
Private pdf = renderer.RenderUrlAsPdf("https://www.nuget.org/packages/IronPdf")

' Apply an HTML-based watermark to the PDF
pdf.ApplyWatermark("<h2 style='color:red'>SAMPLE</h2>", 30, IronPdf.Editing.VerticalAlignment.Middle, IronPdf.Editing.HorizontalAlignment.Center)

' Save the watermarked PDF
pdf.SaveAs("C:\Path\To\Watermarked.pdf")

NReco.PdfGenerator Example: NReco.PdfGenerator does not natively support watermarking.

Familiarity with HTML and CSS can enhance your experience while using IronPDF's watermarking tool. You will have full control over the watermarking process. The intuitive and easy-to-learn aspects of the watermarking control will make you feel proficient in no time.

If you are using NReco.PdfGenerator and want to watermark your newly converted PDF files, you will need to install an external library, such as PDFSharp.

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

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

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

using IronPdf;
using IronPdf.Editing;

// Instantiate the renderer and render a PDF from HTML
ChromePdfRenderer renderer = new ChromePdfRenderer();
PdfDocument pdf = renderer.RenderHtmlAsPdf("<h1>Example HTML Document!</h1>");

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

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

Imports IronPdf
Imports IronPdf.Editing

' Instantiate the renderer and render a PDF from HTML
Private renderer As New ChromePdfRenderer()
Private pdf As PdfDocument = renderer.RenderHtmlAsPdf("<h1>Example HTML Document!</h1>")

' Create a text stamper and customize its settings

	.UseGoogleFont = True,
	.FontSize = 30,
	.IsBold = True,
	.IsItalic = True,
	.VerticalAlignment = VerticalAlignment.Top
}

' Apply text stamp to the PDF
pdf.ApplyStamp(textStamper)
pdf.SaveAs("stampText.pdf")

using IronPdf;
using IronPdf.Editing;
using System;

// Instantiate the renderer and render a PDF from HTML
ChromePdfRenderer renderer = new ChromePdfRenderer();
PdfDocument pdf = renderer.RenderHtmlAsPdf("<h1>Example HTML Document!</h1>");

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

// Apply image stamp to the PDF
pdf.ApplyStamp(imageStamper, 0);
pdf.SaveAs("stampImage.pdf");

using IronPdf;
using IronPdf.Editing;
using System;

// Instantiate the renderer and render a PDF from HTML
ChromePdfRenderer renderer = new ChromePdfRenderer();
PdfDocument pdf = renderer.RenderHtmlAsPdf("<h1>Example HTML Document!</h1>");

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

// Apply image stamp to the PDF
pdf.ApplyStamp(imageStamper, 0);
pdf.SaveAs("stampImage.pdf");

Imports IronPdf
Imports IronPdf.Editing
Imports System

' Instantiate the renderer and render a PDF from HTML
Private renderer As New ChromePdfRenderer()
Private pdf As PdfDocument = renderer.RenderHtmlAsPdf("<h1>Example HTML Document!</h1>")

' Apply image stamp to the PDF
pdf.ApplyStamp(imageStamper, 0)
pdf.SaveAs("stampImage.pdf")

NReco.PdfGenerator Example: NReco.PdfGenerator does not natively support HTML stamping.

IronPDF offers robust text and image stamping tools. With an approach that closely resembles HTML and CSS, you will have total control over the stamping process. In contrast, NReco.PdfGenerator requires an external library such as iTextSharp or PDFSharp to stamp text and images onto your newly converted PDF documents.

For more stamping examples, visit the IronPDF How-To guide on this topic.

DOCX 到 PDF 轉換

IronPDF 示例：

using IronPdf;

// Instantiate the DOCX to PDF Renderer
DocxToPdfRenderer renderer = new DocxToPdfRenderer();

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

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

using IronPdf;

// Instantiate the DOCX to PDF Renderer
DocxToPdfRenderer renderer = new DocxToPdfRenderer();

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

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

Imports IronPdf

' Instantiate the DOCX to PDF Renderer
Private renderer As New DocxToPdfRenderer()

' Render a DOCX file as PDF
Private pdf As PdfDocument = renderer.RenderDocxAsPdf("Modern-chronological-resume.docx")

' Save the converted PDF
pdf.SaveAs("pdfFromDocx.pdf")

NReco.PdfGenerator Example: NReco.PdfGenerator does not natively support DOCX to PDF conversion.

Using IronPDF, you can convert your DOCX files to a PDF format in just a few lines of code. This tool simplifies the implementation process, ensuring an efficient workspace without sacrificing quality in the resulting PDF files. With NReco.PdfGenerator, you cannot perform DOCX to PDF conversions as the library primarily focuses on HTML to PDF conversion. You will need an additional library such as Apsose.Words to handle DOCX to PDF conversion.

NReco.PdfGenerator: Limited Bootstrap Support

NReco.PdfGenerator relies on WkHtmlToPdf with the legacy Qt WebKit engine, which has significant limitations with modern CSS frameworks:

• 無flexbox支持：Bootstrap 4+高度依賴於flexbox，而Qt WebKit不能完全支持
• 有限的CSS網格：現代網格佈局無法正確渲染
• 已過時：Qt WebKit最後一次更新是在2016年，不支持現代CSS3功能
• 需要權宜之計：開發人員必須使用較舊的Bootstrap版本（Bootstrap 3或更早）或實施基於表格的回退方案
