Native .NET library to generate PDF from HTML RRS feed

  • Question




    I want to convert a html output into a PDF file using C#.


    Is there any native .NET library/components available?


    As I searched, noticed every one is going for 3rd party components.


    Thanks in advance.

  • The Adobe Acrobat SDK doesn't provide a method to Create PDF from HTML .

    There are numerous third party tools available .

    One such example is  "iTextSharp" , its a free .NET API for PDF Related operations. It has a

    iTextSharp.text.html.HtmlParser class for Parsing and converting the html to PDF .

  • Here are several solutions.


    1.Generate PDF documents from a HTML page using ASP.NET


    2.Pdfizer, a dumb HTML to PDF converter, in C#


    3.Recommend ExpertPDF. This is a commercial library that converts any web page to PDF.

      It's pure .NET and produces straight PDF from Html.

      You can see live demo using the online free html to pdf converter.

      For detail see this thread and this thread.


      Hope that helps!

  • Hi Karthik


    I'm using PDFSharp in my project which I found very useful for working with PDFs. It's fully .NET managed code, plus it's free! There is also a project called MigraDocLite which might be what you need:

  • Hi,

    The HTML to PDF library for .NET  from http://www.dotnet-reporting.com or the HTML to PDF converter from http://www.winnovative-software.com is what you need. It's pure .NET library, it doesn't use a printer driver. There is also a free html to pdf converter application built on top of this library. The conversion can be done with only a few lines of code:


    PdfConverter pdfConverter = new PdfConverter();
    pdfConverter.PdfDocumentOptions.PdfPageSize = PdfPageSize.A4;
    pdfConverter.PdfDocumentOptions.PdfPageOrientation = PDFPageOrientation.Portrait;
    pdfConverter.PdfDocumentOptions.PdfCompressionLevel = PdfCompressionLevel.Normal;
    pdfConverter.PdfDocumentOptions.GenerateSelectablePdf = true;
    pdfConverter.PdfDocumentOptions.ShowFooter = false;
    pdfConverter.PdfDocumentOptions.ShowHeader = false;
    pdfConverter.LicenseFilePath = Server.MapPath(@"~/Bin");
    byte[] downloadBytes = pdfConverter.GetPdfFromUrlBytes(MyURL);

  • You may want to take a look at PDFTron PDFNet SDK (http://www.pdftron.com/pdfnet). Among many other options there is HTML2PDF option which is using WebKit rendering engine to convert HTML to PDF  (in .NET, Java, C++, etc).

    The library has many options, however the basic conversion is as simple as:

    using (PDFDoc doc = new PDFDoc()) {
      if ( HTML2PDF.Convert(doc, host + page0))
           doc.Save(output_path + "_01.pdf", SDFDoc.SaveOptions.e_linearized);

    As a starting point check out HTML2PDF sample: http://www.pdftron.com/pdfnet/samplecode.html#HTML2PDF

  • If you're creating a commercial project you may want to look at Elerium HTML to PDF .NET component. I hope this example will help you:

  • Hi, yes unfortunately there is no native .NET library for this task there are solutions for it and I disagree with McFerson, iTextSharp is not difficult to use and they offer in my opinion a nice documentation. Here is is how to convert HTML to PDF with it:

    // Creation a new document.
    Document document = new Document(PageSize.A4, 80, 50, 30, 65);
    // Create a writer that listens to the document and directs a XML-stream to a file.
    PdfWriter.getInstance(document, new FileStream("Sample.pdf", FileMode.Create));
    // Parse the HTML file.
    HtmlParser.parse(document, "Sample.html");

    For a really simple and straightforward approach you can also try this C# Word component. Here is how to convert HTML to PDF in C# with it:

    // Convert HTML to PDF.

  • I guess there aren't any native components, since everyone seems to be recommending their favorite third-party stuff. So I'll just join the fun and recommend mine, you can use GemBox.Document to convert HTML to PDF

    It's as simple as:

  • As per my knowledge, there is not such Library is provided by .net to convert HTML to PDF but there are several 3 party dot net libraries to do this job. Some of them are free as under GNU General Public licensebut not for commercial use for that you need to get a license which is not for free. Some of the best libraries for C# are...

    1. itextsharp.
    2. pdfsharp.
    3. pdfclown.
    4. wkhtmltopdf.

    If pricing is not a concern and you are willing to spend enough then I would like to recommend you, Prince, as it is best among all of them surely the price is high but it's worth.

  • For html to pdf conversion on C# I used easyPDF SDK solution and insert just a few lines of code. Cannot tell you it is the best tool in the market but works good to me. But you may check it out, it has a free trial.

  • As the majority says, you'd have to use third party library for it. As for what I am using and you can try as well, it is https://zetpdf.com/. It is a great tool.

  • You can try using this ZetPDF.com platform  that  has a fastest pdf sdk for .net applications.

  • To get a really good HTML to PDF conversion you need to use a browser to properly parse the CSS, JavaScript and images into the PDF. That is why I would unfortunately recommend a third party provider such as GrabzIt's HTML to PDF .NET library https://grabz.it/html-to-pdf-image-api.aspx, to get a decent conversion.
