Installing IronPDF 2021

To Install:

PM> Install-Package IronPdf

Upgrade Guide for Existing Users

IronPdf updates all usages of your existing HtmlToPdf and AspToPdf code to use our new Chrome Rendering Engine.

Remove any reference to IronPdf.Threading which is now legacy software. The IronPdf main package is threading and async compatible!

Try out the new 2021 API

We haven’t broken the IronPDF API you are using, it will remain! However, the old style is being superseded by a better one to give you more control. For examples you now have Print options and Http Login controls specific to your renderer

using IronPdf;
//...
ChromePdfRenderer Renderer = new ChromePdfRenderer();
Renderer.RenderingOptions.FitToPaper = true;
Renderer.RenderingOptions.CssMediaType = IronPdf.Rendering.PdfCssMediaType.Screen;
Renderer.RenderingOptions.PrintHtmlBackgrounds = true;
Renderer.RenderingOptions.CreatePdfFormsFromHtml = true;
var doc = Renderer.RenderHtmlAsPdf(“<h1>Hello world!</h1>“);
//var doc = Renderer.RenderUrlAsPdf(“https://www.google.com/”);
//var doc = Renderer.RenderHtmlFileAsPdf(“example.html”);
doc.SaveAs(“google_chrome.pdf”);

Pixel perfect Chrome rendering!

This example will give you PDFs which are pixel perfect to the latest chrome desktop browser’s “print to pdf” functionality:

ChromePdfRenderer Renderer = new ChromePdfRenderer();
Renderer.RenderingOptions.CssMediaType = IronPdf.Rendering.PdfCssMediaType.Print;
Renderer.RenderingOptions.PrintHtmlBackgrounds = false;
Renderer.RenderingOptions.CreatePdfFormsFromHtml = false;
var doc = Renderer.RenderUrlAsPdf(“https://www.google.com/”);

However...we would recommend using improved features such as:

Using screen stylesheets to print PDFs which are less fiddly to develop and more true to existing web assets.

• Responsive layout support
• Creating PDF Forms from your HTML form elements.

ChromePdfRenderer Renderer = new ChromePdfRenderer();
Renderer.RenderingOptions.CssMediaType = IronPdf.Rendering.PdfCssMediaType.Screen;
Renderer.RenderingOptions.PrintHtmlBackgrounds = true;
Renderer.RenderingOptions.CreatePdfFormsFromHtml = true;
Renderer.RenderingOptions.ViewportWidth = 1080 ; //px
var doc = Renderer.RenderUrlAsPdf(“https://www.google.com/”);

Comparing Chrome and WebKit

You can use the IronPdf.Rendering.AdaptivePdfRenderer to switch between the ‘Chrome’ and ‘WebKit’ rendering at an instance level if you preferred the old rendering style for some of your application, or dont want to break unit tests.

using IronPdf;
//...
IronPdf.Rendering.AdaptivePdfRenderer Renderer = new IronPdf.Rendering.AdaptivePdfRenderer();
Renderer.RenderingOptions.RenderingEngine = IronPdf.Rendering.PdfRenderingEngine.Chrome;  //switch between Chrome and WebKit here
var doc = Renderer.RenderHtmlAsPdf(“<h1>Hello world!</h1>“);

Use every CPU core available!

• Multithreading and Async support for our Chrome rendering engine is in a different league to previous build.
• For enterprise grade multi-threading use our Chrome in your existing threads and it will work. For web applications this also takes zero setup.
• For batch processing for HtmlToPdf we suggest using the built in .NETParallel.ForEach
• We love async and have provided Async variants of methods such as ChromePdfRenderer.RenderHtmlAsPdf
