I want to generate a PDF by passing HTML contents to a function. I have made use of iTextSharp for this but it does not perform well when it encounters tables and the layout just gets messy.

Is there a better way?

Update: I would now recommend PupeteerSharp over wkhtmltopdf.

Try wkhtmtopdf. It is the best tool I have found so far.

For .NET, you may use this small library to easily invoke wkhtmtopdf command line utility.

EDIT: New SuggestionHTML Renderer for PDF using PdfSharp

(After trying wkhtmltopdf and suggesting to avoid it)

HtmlRenderer.PdfSharp is a 100% fully C# managed code, easy to use, thread safe and most importantly FREE(New BSD License) solution.

Usage

1. Download HtmlRenderer.PdfSharp nuget package.

2. Use Example Method.

A very Good Alternate Is a Free Version of iTextSharp

Until version 4.1.6 iTextSharp was licensed under the LGPL licence and versions until 4.16 (or there may be also forks) are available as packages and can be freely used. Of course someone can use the continued 5+ paid version.

I tried to integrate wkhtmltopdf solutions on my project and had a bunch of hurdles.

I personally would avoid using wkhtmltopdf - based solutions on Hosted Enterprise applications for the following reasons.

1. First of all wkhtmltopdf is C++ implemented not C#, and you willexperience various problems embedding it within your C# code,especially while switching between 32bit and 64bit builds of yourproject. Had to try several workarounds including conditionalproject building etc. etc. just to avoid 'invalid format exceptions'on different machines.
2. If you manage your own virtual machine its ok. But if your projectis running within a constrained environment like (Azure(Actually is impossible withing azure as mentioned by theTuesPenchin author) , Elastic Beanstalk etc) it's a nightmare to configure that environment only for wkhtmltopdf to work.
3. wkhtmltopdf is creating files within your server so you have tomanage user permissions and grant 'write' access to wherewkhtmltopdf is running.
4. Wkhtmltopdf is running as a standalone application, so its notmanaged by your IIS application pool. So you have to either host itas a service on another machine or you will experience processing spikes and memory consumption within your productionserver.
5. It uses temp files to generate the pdf, and in cases Like AWSEC2 which has really slow disk i/o it is a big performanceproblem.
6. The most hated 'Unable to load DLL 'wkhtmltox.dll' error reportedby many users.

For anyone who want to generate pdf from html in simpler applications / environments I leave my old post as suggestion.

or Especially For MVC Web Applications (But I think you may use it in any .net application)

They both utilize the wkhtmtopdf binary for converting html to pdf. Which uses the webkit engine for rendering the pages so it can also parse css style sheets.

They provide easy to use seamless integration with C#.

Rotativa can also generate directly PDFs from any Razor View.

Additionally for real world web applications they also manage thread safety etc...

Most HTML to PDF converter relies on IE to do the HTML parsing and rendering. This can break when user updates their IE. Here is one that does not rely on IE.

The code is something like this:

Like many other converters, you can pass text, file name, or Url. The result can be saved into a file or a stream.

I recently performed a PoC regarding HTML to PDF conversion and wanted to share my results.

My favorite by far is OpenHtmlToPdf

Advantages of this tool:

• Very good HTML compatibility (e.g. it was the only tool in my example that correctly repeated table headers when a table spanned multiple pages)
• Fluent API
• Free and OpenSource (Creative Commons Attribution 3.0 license)
• Available via NuGet

Other tools tested:

• ExpertPDF (http://www.html-to-pdf.net/)
• IronPDF (http://ironpdf.com/)
• iTextSharp (https://sourceforge.net/projects/itextsharp/)
• NReco PDF Creator for .NET(http://www.nrecosite.com/pdf_generator_net.aspx)
• HTML renderer for PDF Sharp(https://www.nuget.org/packages/HtmlRenderer.PdfSharp/)
• SelectPDF community edition (http://selectpdf.com/community-edition/)

I highly recommend NReco, seriously. It has the free and paid version, and really worth it. It uses wkhtmtopdf in background, but you just need one assembly. Fantastic.

Example of use:

Install via NuGet.

Disclaimer: I'm not the developer, just a fan of the project :)

Winnovative offer a .Net PDF library that supports HTML input. They offer an unlimited free trial. Depending on how you wish to deploy your project, this might be sufficient.

Essential PDF can be used to convert HTML to PDF: C# sample. The sample linked to here is ASP.NET based, but the library can be used from Windows Forms, WPF, ASP.NET Webforms, and ASP.NET MVC. The library offers the option of using different HTML rendering engines : Internet Explorer (default) and WebKit (best output).

The whole suite of controls is available for free (commercial applications also) through the community license program if you qualify. The community license is the full product with no limitations or watermarks.

Note: I work for Syncfusion.

I used ExpertPDF Html To Pdf Converter. Does a decent job. Unfortunatelly, it's not free.

There's also a new web-based document generation app - DocRaptor.com. Seems easy to use, and there's a free option.

If you don't really need a true .Net PDF library, there are numerous free HTML to PDF tools, many of which can run from a command-line.

One solution would be to pick one of those and then write a thin wrapper around that in C#. E.g., as done in this tutorial.

There are good news for HTML-to-PDF demands. As this answer showed, the W3C standard css-break-3 will solve the problem... It is a Candidate Recommendation with plan to turn into definitive Recommendation in 2017 or 2018, after tests.

As not-so-standard there are solutions, with plugins for C#, as showed by print-css.rocks.

ABCpdf.NET (http://www.websupergoo.com/abcpdf-5.htm)

We use and recommend.

Very good component, it not only convert a webpage to PDF like an image but really convert text, image, formatting, etc...

It's not free but it's cheap.

Below is an example of converting html + css to PDF using iTextSharp (iTextSharp + itextsharp.xmlworker)

It depends on any other requirements you have.

A really simple but not easily deployable solution is to use a WebBrowser control to load the Html and then using the Print method printing to a locally installed PDF printer. There are several free PDF printers available and the WebBrowser control is a part of the .Net framework.

EDIT:If you Html is XHtml you can use PDFizer to do the job.

PDF Vision is good. However, you have to have Full Trust to use it. I already emailed and asked why my HTML wasn't being converted on the server but it worked fine on localhost.

I found the following library more effective in converting html to pdf.
nuget: https://www.nuget.org/packages/Select.HtmlToPdf/

If none of the options above help you you can always search the NuGet packages https://www.nuget.org/packages?q=html+pdf

I was also looking for this a while back. I ran into HTMLDOC http://www.easysw.com/htmldoc/ which is a free open source command line app that takes an HTML file as an argument and spits out a PDF from it. It's worked for me pretty well for my side project, but it all depends on what you actually need.

The company that makes it sells the compiled binaries, but you are free to download and compile from source and use it for free. I managed to compile a pretty recent revision (for version 1.9) and I intend on releasing a binary installer for it in a few days, so if you're interested I can provide a link to it as soon as I post it.

Edit (2/25/2014): Seems like the docs and site moved to http://www.msweet.org/projects.php?Z1

You need to use a commercial library if you need perfect html rendering in pdf.

ExpertPdf Html To Pdf Converter is very easy to use and it supports the latest html5/css3. You can either convert an entire url to pdf:

or a html string:

You also have the alternative to directly save the generated pdf document to a Stream of file on the disk.

I'm the author of the Rotativa package. It allows to create PDF files directly from razor views:

Trivial to use and you have full control on the layout since you can use razor views with data from your Model and ViewBag container.

I developed a SaaS version on Azure. It makes it even easier to use it from WebApi or any .Net app, service, Azure website, Azure webjob, whatever runs .Net.

Free accounts available.

Winnovative Html To Pdf Converter Freeware

Ok, using this technologies....

The src can be downloaded from here it needs nant

Instead of parsing HTML directly to PDF, you can create an Bitmap of your HTML-page and then insert the Bitmap into your PDF, using for example iTextSharp.

Here's a code how to get an Bitmap of an URL. I found it somewhere here on SO, if I find the source I'll link it.

With Winnovative HTML to PDF converter you can convert a HTML string in a single line

The base URL is used to resolve the images referenced by relative URLs in HTML string. Alternatively you can use full URLs in HTML or embed images using src='data:image/png' for image tag.

In answer to 'fubaar' user comment about Winnovative converter, a correction is necessary. The converter does not use IE as rendering engine. It actually does not depend on any installed software and the rendering is compatible with WebKit engine.

If you want user to download the pdf of rendered page in the browser then the easiest solution to the problem is

on client side it will prompt user to save pdf of current page. You can also customize the appearance of pdf by linking style

print.css is applied to the html while printing.

Limitation

You can't store the file on server side.User prompt to print the page than he had to save page manually.Page must to be rendered in a tab.
