Start Using HiQPdf

You can start by copying the C# code below in your application or you can start with our demo applications for .NET from downloadable product packages.

C# Code Samples for HTML to PDF

The C# code samples below show how to quickly produce PDF documents from HTML pages or HTML code and save the resulted PDF to a memory buffer, to a PDF file or send it to browser for download when created in ASP.NET applications.

At the top of your C# source file you have to add the 'using HiQPdf;' instruction to make available the HiQPdf namespace to your application code.

// Include the HiQPdf namespace at the top of your C# file
using HiQPdf;

You can use the C# code below to convert a HTML code or a HTML page from a given URL to a PDF file.

// Create the HTML to PDF converter object
HtmlToPdf converter = new HtmlToPdf();

// Convert the HTML code to a PDF file
converter.ConvertHtmlToFile("<b>Hello World</b> from HiQPdf !", null, "html_to_file.pdf");

// Convert the HTML page from URL to a PDF file
string urlToConvert = "http://www.hiqpdf.com";
converter.ConvertUrlToFile(urlToConvert, "url_to_file.pdf");

Alternatively you can produce the PDF document in a memory buffer that you can further save to a file on server.

// Create the HTML to PDF converter object
HtmlToPdf converter = new HtmlToPdf();

// Convert the HTML code to memory
byte[] htmlToPdfData = converter.ConvertHtmlToMemory("<b>Hello World</b> from HiQPdf !", null);

// Save the PDF data to a file
System.IO.File.WriteAllBytes("html_to_memory.pdf", htmlToPdfData);

// Convert the HTML page from URL to memory
string urlToConvert = "http://www.hiqpdf.com";
byte[] urlToPdfData = converter.ConvertUrlToMemory(urlToConvert);

// Save the PDF data to a file
System.IO.File.WriteAllBytes("url_to_memory.pdf", urlToPdfData);

The C# code below can be used in your ASP.NET Core and ASP.NET MVC applications to convert a HTML code to PDF in a memory buffer and then send the PDF data for download to browser.

// Create the HTML to PDF converter object
HtmlToPdf converter = new HtmlToPdf();

// Convert the HTML code to memory
byte[] htmlToPdfData = converter.ConvertHtmlToMemory("<b>Hello World</b> from HiQPdf !", null);

FileResult fileResult = new FileContentResult(htmlToPdfData, "application/pdf");
fileResult.FileDownloadName = "html_to_pdf.pdf";
return fileResult;

The C# code below can be used in your ASP.NET Web Forms applications to convert a HTML code to PDF in a memory buffer and then send the PDF data for download to browser.

// Create the HTML to PDF converter object
HtmlToPdf converter = new HtmlToPdf();

// Convert the HTML code to memory
byte[] htmlToPdfData = converter.ConvertHtmlToMemory("<b>Hello World</b> from HiQPdf !", null);

HttpResponse httpResponse = HttpContext.Current.Response;
httpResponse.AddHeader("Content-Type", "application/pdf");
httpResponse.AddHeader("Content-Disposition",
    String.Format("attachment; filename=html_to_pdf.pdf; size={0}",
    htmlToPdfData.Length.ToString()));
httpResponse.BinaryWrite(htmlToPdfData);
httpResponse.End();
