Our Syncfusion HTML-to-PDF converter is a .NET PDF library for converting webpages, SVG MHTML and HTML files to PDF using C#. It uses the popular rendering engine Blink (Google Chrome). It is reliable and accurate. The result preserves all graphics, images, text, fonts, and the layout of the original HTML document or webpage. You have the flexibility to customize fonts in header and footer elements of your generated PDF. This can be achieved by utilizing the PdfTrueTypeFont class from the Syncfusion.Pdf.Graphics namespace. To apply a custom font, you first need to load the desired font from a file and pass it into the PdfTrueTypeFont constructor. The PdfTrueTypeFont constructor accepts parameters like the font file path, font size, and style (e.g., bold, italic). Once the font is initialized, you can assign it to the header or footer elements of the PDF. Steps to adding custom font in footer while performing HTML to PDF conversion Create a new console application project. Install the Syncfusion.HtmlToPdfConverter.Winforms NuGet package as a reference to your console application from Nuget.org. Include the following namespaces in the Program.cs file. C# using System.Drawing; using Syncfusion.HtmlConverter; using Syncfusion.Pdf; using Syncfusion.Pdf.Graphics; Use the following code sample in Program.cs to add custom font in footer while performing HTML to PDF conversion C# // Initialize the HTML to PDF converter HtmlToPdfConverter htmlConverter = new HtmlToPdfConverter(); BlinkConverterSettings blinkConverterSettings = new BlinkConverterSettings(); // Create font and brush for the footer element FileStream fontStream = new FileStream(@"calibri.ttf", FileMode.Open, FileAccess.Read); PdfFont font = new PdfTrueTypeFont(fontStream, 10); PdfBrush brush = new PdfSolidBrush(Color.Black); // Create a PDF page template element for the footer with specified bounds PdfPageTemplateElement footer = new PdfPageTemplateElement(new RectangleF(0, 0, blinkConverterSettings.PdfPageSize.Width, 50)); // Create a page number field for the footer PdfPageNumberField pageNumber = new PdfPageNumberField(font, PdfBrushes.Black); // Create a page count field for the footer PdfPageCountField count = new PdfPageCountField(font, PdfBrushes.Black); // Add page number and page count fields to a composite field for formatted display PdfCompositeField compositeField = new PdfCompositeField(font, PdfBrushes.Black, "Page {0} of {1}", pageNumber, count); // Draw the composite field in the footer compositeField.Draw(footer.Graphics, PointF.Empty); // Assign the footer element to the PDF footer settings of the Blink converter blinkConverterSettings.PdfFooter = footer; // Set the Blink viewport size blinkConverterSettings.ViewPortSize = new Size(1024, 0); // Assign the Blink converter settings to the HTML converter htmlConverter.ConverterSettings = blinkConverterSettings; // Convert the specified URL to PDF PdfDocument document = htmlConverter.Convert("https://www.google.com/"); // Create a file stream to save the generated PDF using(FileStream fileStream = new FileStream("Output.pdf", FileMode.Create, FileAccess.ReadWrite)) { // Save the PDF document to the file stream document.Save(fileStream); } // Close the document document.Close(true); A complete working sample can be downloaded from HTML-to-PDF-Framework-Footer-Custom-Font By executing the program, a PDF file will be generated with the footer text displayed in the Calibri font, as shown below.

It is reliable and accurate. The result preserves all graphics, images, text, fonts, and the layout of the original HTML document or webpage. Using this library, you can add the Arabic text in the TOC of the PDF when performing HTML to PDF conversion. We used arial-unicode-ms font that supports Arabic text, you can specify such font under PdfTrueTypeFont class and assign it to HtmlToPdfTocStyle. However, if you want to use a different font that supports Arabic text then you can replace it. Steps to adding multi-language support, including Arabic, for TOC in HTML to PDF conversion Create a new console application project. Install the Syncfusion.HtmlToPdfConverter.Net.Windows NuGet package as a reference to your console application from Nuget.org. Include the following namespaces in the Program.cs file. C# using Syncfusion.Drawing; using Syncfusion.HtmlConverter; using Syncfusion.Pdf; using Syncfusion.Pdf.Graphics; using Syncfusion.Pdf.HtmlToPdf; Use the following code sample in Program.cs to add multi-language support, including Arabic, for TOC in HTML to PDF conversion C# //Initialize the HTML to PDF converter. HtmlToPdfConverter htmlConverter = new HtmlToPdfConverter(); //Initialize blink converter settings. BlinkConverterSettings settings = new BlinkConverterSettings(); //Enable TOC. settings.EnableToc = true; //Set the style for level 1(H1) items in table of contents. HtmlToPdfTocStyle tocstyleH1 = new HtmlToPdfTocStyle(); // Load the Arabic font from a file PdfFont arabicFont = new PdfTrueTypeFont(@"Data/arial-unicode-ms.ttf", 10, PdfFontStyle.Regular); // Set the TOC style with the Arabic font tocstyleH1.Font = arabicFont; // Set the background color tocstyleH1.BackgroundColor = new PdfSolidBrush(new PdfColor(Color.FromArgb(68, 114, 196))); // Set the foreground color tocstyleH1.ForeColor = PdfBrushes.White; // Set the padding tocstyleH1.Padding = new PdfPaddings(5, 5, 3, 3); settings.Toc.SetItemStyle(1, tocstyleH1); settings.Toc.SetItemStyle(2, tocstyleH1); settings.Toc.SetItemStyle(3, tocstyleH1); settings.Toc.SetItemStyle(4, tocstyleH1); //Assign Blink converter settings to HTML converter. htmlConverter.ConverterSettings = settings; //Convert HTML to PDF document. PdfDocument document = htmlConverter.Convert(Path.GetFullPath(@"Data/input1.html")); //Create a file stream to save the PDF document. using (FileStream fileStream = new FileStream(Path.GetFullPath(@"Output/HTML-to-PDF.pdf"), FileMode.Create, FileAccess.ReadWrite)) { //Save the PDF document document.Save(fileStream); } //Close the PDF document document.Close(true); A complete working sample can be downloaded from HTML-to-PDF-TOC-Arabic By executing the program, you will get the PDF document as follows. Take a moment to peruse the documentation, where you can find converting HTML pages to PDF document with custom style of TOC. You can use fonts that support other languages beyond Arabic for the Table of Contents (TOC) in your HTML to PDF conversion.

The Syncfusion® HTML to PDF converter is a .NET library that uses C# for converting webpages, SVG, MHTML, and HTML to PDF. It is reliable and accurate. The result preserves all graphics, images, text, fonts, and the layout of the original HTML document or webpage. Due to GDI limitations in Azure App Service windows, the Blink rendering engine does not support HTML conversion directly. As a workaround, we can use Azure functions on Linux to perform HTML to PDF conversion using Blink in the Azure App Service on Windows. How to use Blink HTML to PDF conversion in Azure App Service windows using Azure functions on Linux: To achieve this, we need to create an Azure function app and publish the function to Azure Function Linux. Get the function URL and ensure that the functions are working properly after publishing the Azure Function App. Kindly refer the following KB documentation to create and publish the Azure function Linux with the Blink rendering engine: https://www.syncfusion.com/kb/12908/how-to-convert-html-to-pdf-using-blink-in-azure-functions-linux Create a new ASP.NET Core MVC application. Install the Syncfusion.Pdf.Net.Core NuGet package as a reference to your project from NuGet.org. Add a Convert To PDF button in index.cshtml.@{ Html.BeginForm("ConvertToPDF ", "Home", FormMethod.Post); { <input type="submit" value="Convert To PDF" class=" btn" /> } } Include the following namespaces and code snippet in controller for calling your azure function URL from your azure app service: Note:you can load the converted PDF document and perform the post processing functionalities such as adding encryption, digital signature etc., to the output PDF document. // [C# Code] using System.IO; using Syncfusion.Pdf; using Microsoft.AspNetCore.Hosting; public IActionResult ConvertToPDF() { //Add the Azure function URL to convert HTML to PDF string functionURL = "https://binkhtmltopdflinuxappp.azurewebsites.net/api/Function1?"; //URL to convert to PDF document string url = "https://www.syncfusion.com"; string functionUrlwithParameter = functionURL + "url=" + url; //Create HttpWebRequest with azure functions URL. HttpWebRequest req = (HttpWebRequest)WebRequest.Create(functionUrlwithParameter); //Gets the response from the Azure Functions. HttpWebResponse res = (HttpWebResponse)req.GetResponse(); MemoryStream stream = new MemoryStream(); res.GetResponseStream().CopyTo(stream); PdfLoadedDocument loadedDocument = new PdfLoadedDocument(stream); //Document security. PdfSecurity security = loadedDocument.Security; security.Algorithm = PdfEncryptionAlgorithm.AES; security.OwnerPassword = "syncfusion"; security.UserPassword = "password"; loadedDocument.Save(stream); loadedDocument.Close(); // Save the response stream as PDF document. return File(stream.ToArray(), "application/pdf", "Output.pdf"); } Refer to the following steps to publish as Azure App Windows: Right-click the project and select Publish. Create a new profile in publish target window. Create an App service using Azure subscription and select a hosting plan. After creating a profile, click the publish button. The published webpage will now be shown in the browser. Click Convert to PDF to convert the Google webpage to a PDF.
