Download and install wkhtmltopdf . Use the below code. public static string HtmlToPdf(string outputFilenamePrefix, string[] urls, string[] options = null, string pdfHtmlToPdfExePath = @"C:\Program Files\wkhtmltopdf\bin\wkhtmltopdf.exe") { string urlsSeparatedBySpaces = string.Empty; try { //Determine inputs if ((urls == null) || (urls.Length == 0)) throw new Exception("No input URLs provided for HtmlToPdf"); else urlsSeparatedBySpaces = String.Join(" ", urls); //Concatenate URLs string outputFilename = outputFilenamePrefix + "_" + DateTime.Now.ToString("yyyy-MM-dd-hh-mm-ss-fff") + ".PDF"; // assemble destination PDF file name var p = new System.Diagnostics.Process() { StartInfo = { FileName = pdfHtmlToPdfExePath, Arguments = ((options == null) ? "" : string.Join(" ", options)) + " " + urlsSeparatedBySpaces + " " + outputFilename, UseShellExecute = false, // needs to be false in order to redirect output RedirectStandardOutput = true, RedirectStandardError = true, RedirectStandardInput = true, // redirect all 3, as it should be all 3 or none WorkingDirectory = Path.Combine(Path.GetDirectoryName(Assembly.GetEntryAssembly().Location)) } }; p.Start(); // read the output here... var output = p.StandardOutput.ReadToEnd(); var errorOutput = p.StandardError.ReadToEnd(); // ...then wait n milliseconds for exit (as after exit, it can't read the output) p.WaitForExit(60000); // read the exit code, close process int returnCode = p.ExitCode; p.Close(); // if 0 or 2, it worked so return path of pdf if ((returnCode == 0) || (returnCode == 2)) return outputFilename; else throw new Exception(errorOutput); } catch (Exception exc) { throw new Exception("Problem generating PDF from HTML, URLs: " + urlsSeparatedBySpaces + ", outputFilename: " + outputFilenamePrefix, exc); } } And call the above method as HtmlToPdf("test", new string[] { "https://www.google.com" }, new string[] { "-s A5" }); If you need to convert HTML string to PDF , the tweak the above method and replace the Arguments to Process StartInfo as $@"/C echo | set /p=""{htmlText}"" | ""{pdfHtmlToPdfExePath}"" {((options == null) ? "" : string.Join(" ", options))} - ""C:\Users\xxxx\Desktop\{outputFilename}""";

You can take the HTML page and convert it to PDF through a backend service using the DocumentConverter. Here is an example you can leverage: using (DocumentConverter documentConverter = new DocumentConverter()) { var input = @"C:\Inputfiles\page.html"); var output = @"C:\Outputfiles\output.pdf"); var jobData = DocumentConverterJobs.CreateJobData(input, output, DocumentFormat.Pdf); jobData.JobName = "Convert to Pdf"; var documentWriter = new DocumentWriter(); documentConverter.SetDocumentWriterInstance(documentWriter); var renderingEngine = new AnnWinFormsRenderingEngine(); documentConverter.SetAnnRenderingEngineInstance(renderingEngine); var job = documentConverter.Jobs.CreateJob(jobData); documentConverter.Jobs.RunJob(job); } https://www.leadtools.com/help/sdk/tutorials/dotnet-core-convert-files-with-the-document-converter.html https://www.leadtools.com/help/sdk/tutorials/dotnet-core-configure-and-run-the-document-service.html
