Convert HTML to PDF in ASP.NET MVC

You can use the Free Html To Pdf Converter from SelectPdf (http://selectpdf.com/community-edition/).

Code for MVC looks like this:

[HttpPost] public ActionResult Convert(FormCollection collection) { // read parameters from the webpage string url = collection["TxtUrl"]; string pdf_page_size = collection["DdlPageSize"]; PdfPageSize pageSize = (PdfPageSize)Enum.Parse(typeof(PdfPageSize), pdf_page_size, true); string pdf_orientation = collection["DdlPageOrientation"]; PdfPageOrientation pdfOrientation = (PdfPageOrientation)Enum.Parse( typeof(PdfPageOrientation), pdf_orientation, true); int webPageWidth = 1024; try { webPageWidth = System.Convert.ToInt32(collection["TxtWidth"]); } catch { } int webPageHeight = 0; try { webPageHeight = System.Convert.ToInt32(collection["TxtHeight"]); } catch { } // instantiate a html to pdf converter object HtmlToPdf converter = new HtmlToPdf(); // set converter options converter.Options.PdfPageSize = pageSize; converter.Options.PdfPageOrientation = pdfOrientation; converter.Options.WebPageWidth = webPageWidth; converter.Options.WebPageHeight = webPageHeight; // create a new pdf document converting an url PdfDocument doc = converter.ConvertUrl(url); // save pdf document byte[] pdf = doc.Save(); // close pdf document doc.Close(); // return resulted pdf document FileResult fileResult = new FileContentResult(pdf, "application/pdf"); fileResult.FileDownloadName = "Document.pdf"; return fileResult; } 

VB.NET MVC version of the code can be found here: http://selectpdf.com/convert-from-html-to-pdf-in-asp-net-mvc-csharp-and-vb-net/

In short:

HTML Renderer for PDF using PdfSharp

 public static Byte[] PdfSharpConvert(String html) { Byte[] res = null; using (MemoryStream ms = new MemoryStream()) { var pdf = TheArtOfDev.HtmlRenderer.PdfSharp.PdfGenerator.GeneratePdf(html, PdfSharp.PageSize.A4); pdf.Save(ms); res = ms.ToArray(); } return res; } 

More Detailed Answer

The C# code below can be used in a MVC application to convert the current view to PDF and produce a PDF in a buffer that can be saved on server or sent to browser for download. The code is using evopdf library for .net to perform the HTML to PDF conversion:

[HttpPost] public ActionResult ConvertCurrentPageToPdf(FormCollection collection) { object model = null; ViewDataDictionary viewData = new ViewDataDictionary(model); // The string writer where to render the HTML code of the view StringWriter stringWriter = new StringWriter(); // Render the Index view in a HTML string ViewEngineResult viewResult = ViewEngines.Engines.FindView(ControllerContext, "Index", null); ViewContext viewContext = new ViewContext( ControllerContext, viewResult.View, viewData, new TempDataDictionary(), stringWriter ); viewResult.View.Render(viewContext, stringWriter); // Get the view HTML string string htmlToConvert = stringWriter.ToString(); // Get the base URL String currentPageUrl = this.ControllerContext.HttpContext.Request.Url.AbsoluteUri; String baseUrl = currentPageUrl.Substring(0, currentPageUrl.Length - "Convert_Current_Page/ConvertCurrentPageToPdf".Length); // Create a HTML to PDF converter object with default settings HtmlToPdfConverter htmlToPdfConverter = new HtmlToPdfConverter(); // Convert the HTML string to a PDF document in a memory buffer byte[] outPdfBuffer = htmlToPdfConverter.ConvertHtml(htmlToConvert, baseUrl); // Send the PDF file to browser FileResult fileResult = new FileContentResult(outPdfBuffer, "application/pdf"); fileResult.FileDownloadName = "Convert_Current_Page.pdf"; return fileResult; } 

There is special nuget package RazorPDF. It simple works. RazorPDF site

use ABCpdf dll, here in text area we can write html code and on a button click corresponding pdf will be shown.ABCpdf trail version is easily available for downloding, adding linlk to download the ABCpdf dll https://www.websupergoo.com/download.htm

index.cshtml

 @using (Html.BeginForm("covertopdf", "simple", FormMethod.Post)) { <p style="margin-top:50px"> Input Html: @Html.TextArea("Htmlcontent", new { @class = "form-control",@cols="160" , @rows="20"})<br /> <input type="submit" class="btn-primary" value="Convertopdf" /> </p> } 

SimpleController.cs

 public class SimpleController : Controller { public class FileViewModel { public byte[] Content { get; set; } public string Extension { get; set; } public string FileName { get; set; } } [HttpPost] [ValidateInput(false)] public FileStreamResult covertopdf(string Htmlcontent) //public FileStreamResult covertopdf(file fo) { var result = ExecuteAction(() => { var fileViewmodel = new FileViewModel { Content = ConvertHtmlToPdf(Htmlcontent), //Content= ConvertHtmlToPdf(fo.cont), Extension = "application/pdf", FileName = "Policy Information.pdf" }; return fileViewmodel; }, "covertopdf"); // return result; HttpResponseMessage response = new HttpResponseMessage(HttpStatusCode.OK); // Content is the file Stream stream = new MemoryStream(result.Content); return new FileStreamResult(stream, "application/pdf") { }; } public T ExecuteAction<T>(Func<T> action, string method) { try { return action.Invoke(); } catch (Exception ex) { return default(T); } } protected byte[] ConvertHtmlToPdf(string html, string header = null, string footer = null, bool isPageNumberInFooter = false) { // Create ABCpdf Doc object var doc = new Doc(); if (header == null && footer == null) doc.Rect.Inset(20, 20); else doc.Rect.String = "0 70 600 760"; /*padding from left, padding from bottom, width from left, height from bottom*/ // Add html to Doc //html = "<html><head></head><body></body></html>"; int theId = doc.AddImageHtml(html); // Loop through document to create multi-page PDF while (true) { if (!doc.Chainable(theId)) break; doc.Page = doc.AddPage(); theId = doc.AddImageToChain(theId); } var count = doc.PageCount; /*****************Footer area******************/ if (footer != null) { var newfooter = ""; doc.Rect.String = "40 20 580 50"; for (int i = 1; i <= count; i++) { doc.PageNumber = i; if (isPageNumberInFooter) { newfooter = footer.Replace("PageNumber", "Page " + i.ToString() + " of " + count.ToString()); int id = doc.AddImageHtml(newfooter); while (true) { if (!doc.Chainable(id)) break; id = doc.AddImageToChain(id); } } else doc.AddText(footer); } } /*****************Footer area******************/ // Flatten the PDF for (int i = 1; i <= doc.PageCount; i++) { doc.PageNumber = i; doc.Flatten(); } var pdf = doc.GetData(); doc.Clear(); // Get PDF as byte array. Couls also use .Save() to save to disk return pdf; } } 

There are a number of html to pdf converters for .NET available out there. I can recommend ExpertPdf (www.html-to-pdf.net).

Code looks something like this:

PdfConverter pdfConverter = new PdfConverter(); pdfConverter.PdfDocumentOptions.PdfPageSize = PdfPageSize.A4; byte[] downloadBytes = pdfConverter.GetPdfFromUrlBytes(url); 

There is an online demo here: http://www.html-to-pdf.net/free-online-pdf-converter.aspx

I used iDiTect.Converter to convert html to pdf in asp.net mvc https://www.iditect.com/tutorial/html-to-pdf/, however it's not free code in short

public static Byte[] ConvertToBytes() { HtmlToPdfConverter converter = new HtmlToPdfConverter(); converter.DefaultStyleSheet = ".para{font-size: 24px; color: #FF0000;}"; string htmlContent = "<p class=\"para\">Content with special style.</p><p>Content without style</p>"; converter.Load(htmlContent); return converter.SaveAsBytes(); } 

Canvas to PDF is the right choice to make

function getPDF(){ var HTML_Width = $(".canvas_div_pdf").width(); var HTML_Height = $(".canvas_div_pdf").height(); var top_left_margin = 15; var PDF_Width = HTML_Width+(top_left_margin*2); var PDF_Height = (PDF_Width*1.5)+(top_left_margin*2); var canvas_image_width = HTML_Width; var canvas_image_height = HTML_Height; var totalPDFPages = Math.ceil(HTML_Height/PDF_Height)-1; html2canvas($(".canvas_div_pdf")[0],{allowTaint:true}).then(function(canvas) { canvas.getContext('2d'); console.log(canvas.height+" "+canvas.width); var imgData = canvas.toDataURL("image/jpeg", 1.0); var pdf = new jsPDF('p', 'pt', [PDF_Width, PDF_Height]); pdf.addImage(imgData, 'JPG', top_left_margin, top_left_margin,canvas_image_width,canvas_image_height); for (var i = 1; i <= totalPDFPages; i++) { pdf.addPage(PDF_Width, PDF_Height); pdf.addImage(imgData, 'JPG', top_left_margin, -(PDF_Height*i)+(top_left_margin*4),canvas_image_width,canvas_image_height); } pdf.save("HTML-Document.pdf"); }); };
