The most direct approach you could consider is to convert the HTML page into a rasterized image then save it as a PDF. This will maintain the overall design and images in the page. If you want to also keep text selectable after doing this, you could perform OCR on the result. You can do this with a toolkit like LEADTOOLS (https://www.leadtools.com/downloads?category=main) which has image and document conversion and OCR features that you can use. To convert an HTML page into PDF, there is .NET code you can implement as a service: RasterCodecs codecs = new RasterCodecs (); codecs.convert( "input.html" , "output.pdf" , RasterImageFormat .RasPdfJpeg411, 0, 0, 0, null ); If you want to maintain the text during conversion, another thing you can try is the DocumentConverters class: using ( DocumentConverter documentConverter = new DocumentConverter ()) { var format = DocumentFormat .Pdf; var jobData = DocumentConverterJobs .CreateJobData(inFile, outFile, format); jobData.JobName = "conversion job" ; var job = documentConverter.Jobs.CreateJob(jobData); documentConverter.Jobs.RunJob(job); } Check out this forum topic for more features that can be implemented with ASP.NET MVC, including OCR: https://www.leadtools.com/support/forum/posts/m41793-HTML5-Projects-with-ASP-NET#post41793

Try this code using Spire.PDF. It enables you to convert a HTML page that contains image to PDF. PdfDocument pdf = new PdfDocument(); PdfPageSettings setting = new PdfPageSettings(); setting.Size = PdfPageSize.A4; PdfHtmlLayoutFormat htmlLayoutFormat = new PdfHtmlLayoutFormat(); htmlLayoutFormat.IsWaiting = false ; string htmlCode = File.ReadAllText( "HTML example.html" ); Thread thread = new Thread(() => { pdf.LoadFromHTML(htmlCode, false , setting, htmlLayoutFormat); }); thread .SetApartmentState(ApartmentState.STA); thread .Start(); thread .Join(); pdf.SaveToFile( "Html2Pdf.pdf" ); reference: https://janewdaisy.wordpress.com/2017/02/07/convert-html-string-to-pdf-using-free-api-in-c/ If you need to covnert a URL to PDF, then check this link: https://www.e-iceblue.com/Tutorials/Spire.PDF/Spire.PDF-Program-Guide/Convert-HTML-to-PDF-with-New-Plugin.html
