IronPDF allows developers to create PDF documents easily in C#, F#, and VB.NET for .NET Core and .NET Framework.

In this example, we show that a PDF document can be rendered from any HTML. This allows us to create PDFs that closely match the branding of existing websites.

You can choose simple HTML like the above or incorporate CSS, images, and JavaScript.

This HTML to PDF conversion process also allows PDF design to be delegated to web designers, rather than being tasked to back-end coders.

IronPDF uses a pixel-perfect Chrome rendering engine to turn your HTML5 with CSS3 and JavaScript support into PDF documents. This can take the form of strings, external files, or external URLs, all of which can be rendered to PDF easily using IronPDF.

Here's an example in C# to demonstrate the conversion of HTML to PDF using IronPDF:

using System;
using IronPdf; // Import IronPdf namespace to use its PDF conversion capabilities

class Program
{
    static void Main()
    {
        // Create a new HtmlToPdf object to convert HTML to PDF
        var htmlToPdf = new HtmlToPdf();

        // Define the HTML content for conversion
        string htmlContent = "<h1>Hello, World!</h1><p>This is a PDF generated from HTML.</p>";

        // Convert HTML content to a PDF document
        // Specify the output file name as "output.pdf"
        var pdf = htmlToPdf.RenderHtmlAsPdf(htmlContent);

        // Save the PDF document to the specified file path
        pdf.SaveAs("output.pdf");

        Console.WriteLine("PDF created successfully from HTML.");
    }
}

using System;
using IronPdf; // Import IronPdf namespace to use its PDF conversion capabilities

class Program
{
    static void Main()
    {
        // Create a new HtmlToPdf object to convert HTML to PDF
        var htmlToPdf = new HtmlToPdf();

        // Define the HTML content for conversion
        string htmlContent = "<h1>Hello, World!</h1><p>This is a PDF generated from HTML.</p>";

        // Convert HTML content to a PDF document
        // Specify the output file name as "output.pdf"
        var pdf = htmlToPdf.RenderHtmlAsPdf(htmlContent);

        // Save the PDF document to the specified file path
        pdf.SaveAs("output.pdf");

        Console.WriteLine("PDF created successfully from HTML.");
    }
}

Explanation:

Import Namespace: We need to include the IronPdf namespace which contains all the necessary classes and methods required for HTML to PDF conversion.
Create HtmlToPdf Object: HtmlToPdf htmlToPdf = new HtmlToPdf(); instantiates an object that can handle the conversion process.
Define HTML Content: We specify the HTML content that we wish to convert into PDF format.
Conversion and Saving:
- RenderHtmlAsPdf method of the HtmlToPdf class is used to perform the conversion of the HTML string to a PDF document.
- SaveAs method saves the newly created PDF document to the file system with a specified file name, in this case, "output.pdf".
Console Feedback: Outputs a simple message to the console to confirm that the PDF creation was successful.

With IronPDF, you can create new PDF documents from simple HTML strings within your .NET project, and IronPDF is able to be used in C#, F#, and VB.NET. Thanks to the use of the ChromePdfRenderer class, you can be sure that any PDF documents you render from HTML strings will come out pixel-perfect. With IronPDF's powerful HTML to PDF conversion features, you create high-quality PDF files tailored to fit your personal needs.

The 4 Steps to Converting HTML String to PDF

Import the IronPDF library.
Initialize a new ChromePdfRenderer object.
Use the RenderHtmlAsPdf method.
Save the PDF using PdfDocument.SaveAs.

See the code example below for more details:

The first step to converting an HTML string to a PDF in C# is ensuring that you have the IronPDF library properly set up and working within your project. By including using IronPdf, we make sure we can access the classes needed from the IronPDF library to carry out HTML to PDF conversion. The next line, Installation.EnableWebSecurity = true, is conceptually used to disable local disk access or cross-origin requests, ensuring secure operations. (Note: This line was missing from the example but usually pertains to configuration settings to secure PDF rendering operations.)

The example demonstrates how to create an instance of ChromePdfRenderer which handles the conversion of HTML to PDF. The RenderHtmlAsPdf method is used to convert a simple HTML string ("<h1>Hello World</h1>") into a PDF document. This document is saved to the disk using the SaveAs method.

In the advanced example, IronPDF is shown to handle HTML content containing external assets such as images, CSS, and JavaScript. To load these assets, the optional BasePath parameter is used, specifying the directory containing the required files. The resulting PDF, which includes the external assets, is saved using the same SaveAs method. This code example highlights IronPDF's ability to handle both basic and complex HTML content, making it an efficient tool for generating PDFs programmatically.

HTML headers and footers provide a flexible method for creating dynamic headers and footers for your PDF documents. By adding headers and footers through this method, developers have complete control over how their headers and footers look, as they are rendered as independent HTML documents capable of containing their own assets and stylesheets.

Steps to Add Custom HTML Headers and Footers in a PDF with IronPDF

To begin with, you first need to create an instance of the ChromePdfRenderer class, which handles the rendering of HTML content into a pixel-perfect PDF document.

Next, define a footer using the HtmlHeaderFooter class, where you specify the MaxHeight, HTML content for the footer (which in our case includes page numbering), and base URL for image resolution. The footer is styled to display centered page information.

To avoid overlap between the footer and the PDF's main content, set a bottom margin using the MarginBottom property. Similarly, create a header that includes an image (such as a logo) by using the HtmlHeaderFooter class. Here we have set up a BaseUrl to the directory containing your image asset, allowing for proper image resolution during rendering.

Finally, use the MarginTop property to set a top margin that prevents overlap between the header and the content. This example demonstrates how easy it is to implement custom HTML headers and footers in your PDF documents with IronPDF.

There are two methods through which headers and footers may be added to a PDF document. They can either be added as a classic text format, with the option to merge in dynamic data. Or, they can be added through the much more flexible HTML format, which allows developers to render dynamic headers and footers through their HTML content.

Steps to Add Headers and Footers to PDFs with IronPDF

Today we will be looking at how you can add classic text headers and footers into your PDF documents in just a few simple steps. The first step towards adding customized Headers and Footers into your PDF documents is to ensure that the IronPDF library is included in your project with the using IronPdf; statement. Then, instantiate the ChromePdfRenderer, which provides the functionality to render your HTML content in pixel-perfect PDF documents.

Next, configure the header settings. The FirstPageNumber property allows you to specify the starting page number, accommodating for a cover page if needed. The TextHeader properties enable you to customize the appearance, such as drawing a divider line, centering text (in this case, the document URL), selecting the font type and size, and creating a margin at the top of the page for the header.

After configuring the header, set up the footer using the TextFooter properties. Similar to the header, you can draw a divider line, choose the font type and size, and include dynamic content like the current date, time, and page numbers with total pages. Finally, a margin is created at the bottom of the page to accommodate the footer.

By following these steps, you can enhance your PDF documents with informative headers and footers that improve their professionalism and readability.

IronPDF provides developers with strong PDF security options, supporting the customization and setting of PDF metadata, passwords, permissions, and more. With IronPDF's passwords, security, and metadata options, you can create custom permissions and security levels to fit the need of your PDF document. This is done thanks to the use of classes such as the SecuritySettings and MetaData classes. Some options include limiting the PDF documents to be unprintable, setting them to read-only, and 128-bit encryption, and password protection of your PDF documents.

Setting custom metadata works by implementing the MetaData class to access the various PDF metadata options, and setting them with your customized values. This includes changing the author, keywords, modified data, and more. Setting custom security settings includes the ability to set custom user and owner passwords, printing permissions, read-only mode, and more.

5 Steps to setting PDF passwords, metadata, and security

var pdf = PdfDocument.FromFile("encrypted.pdf", "password");
System.Collections.Generic.List<string> metadatakeys = pdf.MetaData.Keys;
var metadatakeys = pdf.MetaData.Keys;
pdf.MetaData.Author = "Satoshi Nakamoto";
pdf.SecuritySettings.MakePdfDocumentReadOnly("secret-key");

In order to begin customizing the security of your PDF documents, you must first load an existing PDF or create a new one. Here, we have loaded an existing password-protected PDF document, where we have input the password needed to open the PDF document. Once the PDF is loaded, we then use pdf.MetaData.Keys to get the PDF's current metadata. To remove existing PDF metadata values, use the RemoveMetaDataKey method. To begin setting new metadata values, use pdf.MetaData.metadataField (e.g., pdf.MetaData.Keywords), and then just assign the new value to it. Metadata fields such as Title and Keywords take string values, whereas the ModifiedData field takes datetime values.

Next, we have set new security settings using the SecuritySettings class. As you can see, there are a variety of settings that you can set here. This gives you full control over the permissions and security levels for each PDF document you work with. To access these settings, you just need to make sure you use pdf.SecuritySettings, followed by the setting you want to adjust. For example, the MakePdfDocumentReadOnly method sets the PDF document to be read-only, encrypting the content at 128-bit. Other options for SecuritySettings include:

AllowUserAnnotations: Controls whether or not users can annotate the PDF.
AllowUserPrinting: Controls printing permissions for the document.
AllowUserFormData: Sets the permissions for whether users can fill-in forms.
OwnerPassword: Sets the owner password for the PDF, which is used to disable or enable the other security settings.
UserPassword: Sets the user password for the PDF, which must be entered in order to open or print the document.

Once you have set the custom metadata, passwords, and security settings for your PDF document, use the pdf.SaveAs method to save your PDF to a specified location.

IronPDF provides methods to 'watermark' PDF documents with HTML.

Using the ApplyStamp method, developers can add an HTML-based watermark to a PDF file. As shown in the example above, the HTML code for the watermark goes as the first argument to the method. Additional arguments to ApplyStamp control the rotation, opacity, and position of the watermark.

Utilize the ApplyStamp method in lieu of the ApplyWatermark method for more granular control over watermark placement. For example, use ApplyStamp to:

Add Text, Image, or HTML watermarks to PDFs
Apply the same watermark to every page of the PDF
Apply different watermarks to specific PDF pages
Adjust the placement of watermarks in front or behind page copy
Adjust the opacity, rotation, and alignment of watermarks with more precision

How to Add Watermarks to PDF Files in C#

Download and install the IronPDF library from NuGet.
Create a new PdfDocument or use an existing PdfDocument file.
Call the ApplyStamp method to add watermarks to the PDF.
Export the PDF file by calling SaveAs.

Example C# Code to Apply a Watermark Using IronPDF

Ensure you have installed the IronPDF library in your project. You can find more detailed instructions on the IronPDF NuGet package page.

Explanation of the Code:

We start by importing the IronPdf library, which provides all necessary classes and methods for PDF manipulation.
A PDF document is created or loaded using PdfDocument.FromFile, specifying the file path of the existing PDF.
HTML content is defined for the watermark. In this case, the watermark displays "Confidential" with specific styling.
The ApplyStamp method is used to overlay the watermark on the PDF. This method allows for detailed customization:
- rotationDegrees: Specifies the rotation, in degrees, of the watermark.
- left and top: Dictate the X and Y position of the watermark, measured from the top-left corner.
- opacity: Determines the transparency of the watermark.
- pageRange: Specifies which pages should receive the watermark, allowing for diverse placement strategies.
Finally, the SaveAs method exports the modified PDF to a new file.

In conclusion, the IronPDF ApplyStamp method allows for precise control over watermarking PDF documents using HTML. This approach is flexible, accommodating various customization needs for positioning, styling, and applying watermarks to specified pages.

You may want to use a specific background and foreground as you create and render your PDF documents in IronPDF. In such a case, you can use an existing or rendered PDF as the background or foreground for another PDF document. This is particularly useful for design consistency and templating.

This example shows you how to use a PDF document as the background or foreground of another PDF document.

You can do this in C# by loading or creating a multi-page PDF as an IronPdf.PdfDocument object.

You can add backgrounds using PdfDocument.AddBackgroundPdf. For more details on background insertion methods, refer to the IronPDF.PdfDocument background documentation; it describes several background insertion methods and their overrides. This adds a background to each page of your working PDF. The background is copied from a page in another PDF document.

You can add foregrounds, also known as "Overlays," using PdfDocument.AddForegroundOverlayPdfToPage. For detailed information on foreground insertion methods, consult the IronPDF.PdfDocument overlay documentation.

This code illustrates how to integrate additional design elements on top of a base PDF using IronPDF. Always refer to the official documentation for more advanced techniques and additional options.

You can create editable PDF documents with IronPDF as easily as a normal document. The PdfForm class is a collection of user-editable form fields within a PDF document. It can be implemented into your PDF render to make it a form or an editable document.

This example shows you how to create editable PDF forms in IronPDF.

PDFs with editable forms can be created from HTML simply by adding <form>, <input>, and <textarea> tags to the document parts.

The PdfDocument.Form.FindFormField method can be used to read and write the value of any form field. The field's name will be the same as the 'name' attribute given to that field in your HTML.

The PdfDocument.Form object can be used in two ways:

Populating Default Values: This can be used to set a default value for form fields that will be displayed in PDF viewers like Adobe Reader.
Reading User Input: After the user fills in the form, the form fields can be accessed and the data read back into your application.

In the example above, we first import the IronPdf library and define a method CreateEditablePdfDocument. This method contains the HTML structure of a simple form with input fields for username and comments. Using the HtmlToPdf renderer, we convert this HTML content into a PDF document.

The pdfDocument.Form is then used to access and manipulate the form fields. We set default values that will appear when the document is opened in a PDF viewer. Finally, the document is saved with the name "EditableForm.pdf", allowing it to be stored or shared with embedded editable fields.

Digitally signing a PDF document helps ensure the document's integrity by providing a method of adding authentication to the PDF itself. With IronPDF, you have several options when it comes to signing a new or existing PDF file. These include digitally signing the PDF document with a certificate, adding a graphical handwritten version of your signature to the PDF, stamping an image of the certificate on the PDF, or simply creating a signature form field on the PDF to prompt user signing.

Steps to Digitally Signing a PDF with IronPDF

The first step in this process is to either load in or create the PDF we want to sign. For this example, we create a new PDF document from HTML content. To do this, you first need to create a new ChromePdfRenderer instance. This is IronPDF's powerful rendering engine used to render HTML, CSS, and JavaScript to PDF without losing quality. We then use the RenderHtmlAsPdf method to render our HTML string into a high-quality PDF document ready to be signed. The resulting PDF is stored in the doc variable.

Next, we need to create our signature. For this example, we sign our PDF document with a certificate. PdfSignature represents the digital signature object for signing the PDF, and it requires the path to the .pfx file we want to use for the signature and the password to access this file. We have included three optional properties: SigningContact adds an email or contact information to the signature metadata, SigningLocation represents where the document is signed, and SigningReason provides the reason for the document being signed.

Next, we sign the PDF document with the PdfSignature object we created. By calling the Sign method, we apply the signature to the PDF document in one easy line. Multiple signing certificates can be applied to the PDF document using this method.

Finally, we save the signed PDF document using the SaveAs method, which saves the PDF to the specified file location.

¿Qué es Blazor?

Blazor puede ejecutar código C# del lado del cliente directamente en el navegador usando WebAssembly. Dado que WebAssembly admite tecnologías .NET, Blazor puede reutilizar código fuente y bibliotecas del backend en aplicaciones frontend desarrolladas con él. Blazor también puede ejecutar lógica de negocios del lado del cliente en el servidor. Usando SignalR, un marco de mensajería en tiempo real, los eventos de la UI del cliente se envían al servidor. Las actualizaciones necesarias de la UI se transmiten al cliente e incorporan en el DOM una vez que se completa la ejecución.

Usando Blazor Hybrid, los desarrolladores pueden crear aplicaciones cliente nativas, multiplataforma usando .NET MAUI y componentes UI de Blazor existentes. Los desarrolladores también pueden incorporar los mismos componentes de UI en entornos de escritorio, web y móviles sin perder acceso a las características nativas de cualquiera de las plataformas. Los desarrolladores también pueden usar Blazor Hybrid para actualizar aplicaciones existentes de WPF y Windows Forms.

Blazor utiliza estándares web abiertos sin depender del uso de complementos o traducción de código. Todos los navegadores web actuales, incluidos los dispositivos móviles, admiten la tecnología del servidor Blazor.

Características de la Biblioteca PDF .NET Usando IronPDF

Cómo funciona IronPDF con Blazor

IronPDF para Blazor permite a los usuarios crear, importar y exportar documentos PDF usando C# y VB.NET. La biblioteca también admite .NET Framework, .NET Core y .NET Standard. IronPDF proporciona dos formas de editar un PDF: una que usa elementos PDF nativos y otra que permite la edición como un documento de flujo.

Rendimiento

La biblioteca IronPDF para Blazor proporciona un rendimiento inigualable y consumo de memoria óptimo; decodifica fotos según sea necesario, comprime contenido usando cifrado FlateDecode e incorpora subconjuntos de fuentes conteniendo solo los glifos más utilizados.

Formularios Interactivos

Use cuadros de texto, botones de radio, cajas de lista y otros controles similares para agregar interactividad a los documentos PDF. De esta manera, los usuarios pueden actualizar y completar datos en el documento PDF según sea necesario. Una vez que los formularios están completos, pueden aplanarse para eliminar los campos interactivos mientras se conservan sus contenidos. Esto es útil para prevenir alteraciones posteriores al documento.

Cifrado

Los documentos PDF pueden cifrarse con una contraseña para proteger información confidencial contra el acceso no autorizado.

Propiedades del Texto

Al producir o actualizar un documento PDF, puede personalizar la apariencia de los elementos textuales y gráficos gracias a una rica API. Los controles estilísticos, incluyendo relleno, texto, trazo, fuente, tamaño de texto y muchos más, pueden usarse para satisfacer cualquier requerimiento de diseño con facilidad.

Cómo IronPDF Crea y Muestra Documentos PDF

IronPDF puede convertir páginas web a PDFs con la ayuda del método RenderHtmlAsPdf . Este método puede aceptar una cadena que contenga el marcado HTML de una página web. De esta manera, el contenido puede ser estilizado en línea según sea deseado antes de ser introducido en el método. Código adicional puede permitir a los usuarios recibir el archivo PDF como una descarga en su computadora cliente.

Del mismo modo, el método RenderUrlAsPdf transforma el contenido HTML de una URL en contenido PDF, incluyendo cualquier referencia a cualquier JavaScript y CSS. IronPDF genera PDFs desde HTML con alta precisión, asegurando un 100 % de semejanza con la página web original. La biblioteca puede manejar diseños de páginas web complejas que contengan gráficos, imágenes, tablas, etc. Un método separado permite personalizaciones accesorias en el documento PDF. Las personalizaciones posibles incluyen cambios en los tamaños de página, tamaños de margen, contenido de cabecera/pie de página, etc.

Una vez que un documento PDF ha sido generado, JavaScript del lado cliente puede ser usado para mostrar el documento en el cliente del navegador.
