Ever-improving technology means smarter time-saving solutions for everyone, especially developers. Automation is now the key to the software development processes. Working with PDF files in C# has proved difficult for developers over many years. There is a wide variety of factors to take into account when rendering content from PDF files, and even more so when converting content from different formats to PDF. These issues have now been solved with the completion of numerous libraries designed to read, write, create, and convert to PDF from different formats.
This article will compare two of the most popular PDF libraries for .NET and .NET Core developers. These two libraries are:
IronPDF and PDFCrowd are both libraries that provide methods to create, manipulate and print PDFs in .NET and .NET Core. The next question is to decide which C# PDF Library is best suited for your .NET project? You can weigh up your decision as you read the following comparison between the two libraries and their respective standout features for converting and manipulating PDFs.
Let's have a look at what both libraries have to offer first, and then move on to the comparison itself.
IronPDF .NET PDF Library solution is a dream for developers, especially software engineers who use C#. You can easily create a core PDF library for .NET with this excellent tool.
IronPDF uses a .NET Chromium engine to render HTML pages to PDF files. With HTML to PDF, there is no need to use complex APIs to position or design PDFs. IronPDF supports standard web documents: HTML, ASPX, JS, CSS, and images.
It also enables you to create a .NET PDF library using HTML5, CSS, JavaScript, and images. You can effortlessly edit, stamp, and add headers and footers to a PDF. Further, it makes it very easy to read PDF text and extract images.
Some of the important features include:
Create PDFs (Html to Pdf)
Edit Existing PDF Documents Without Adobe Acrobat
Manipulate Existing PDF Documents
Convert from Multiple Formats
Save and Print

Use the following commands to build the PDFCrowd API Client library:
git clone https://github.com/pdfcrowd/pdfcrowd-dotnetcd pdfcrowd-dotnetmake.bat # on Windowsmake all # on UnixNow that we have created the project and installed the necessary libraries, let's start comparing the IronPDF and PDFCrowd libraries in terms of code.
Both libraries provide the facility to convert an HTML webpage to PDF. Let's have a look at the code for each library one-by-one.
IronPDF makes it very straightforward to render HTML from existing URLs as PDF documents. There is a very high level of support for JavaScript, Images, Forms, and CSS.
The following code uses IronPDF to create a PDF document directly from a website address.
IronPdf.ChromePdfRenderer Renderer = new IronPdf.ChromePdfRenderer();
using var Pdf = Renderer.RenderUrlAsPdf("https://ironpdf.com/");
Pdf.SaveAs("url.pdf");IronPdf.ChromePdfRenderer Renderer = new IronPdf.ChromePdfRenderer();
using var Pdf = Renderer.RenderUrlAsPdf("https://ironpdf.com/");
Pdf.SaveAs("url.pdf");Dim Renderer As New IronPdf.ChromePdfRenderer()
Dim Pdf = Renderer.RenderUrlAsPdf("https://ironpdf.com/")
Pdf.SaveAs("url.pdf")With PDFCrowd it is also very easy to convert URLs into PDF documents. The following code uses PDFCrowd to generate a PDF document directly from a website address.
// create the API client instance
pdfcrowd.HtmlToPdfClient client = new pdfcrowd.HtmlToPdfClient("demo", "ce544b6ea52a5621fb9d55f8b542d14d");
// run the conversion and write the result to a file
client.convertUrlToFile("http://www.pdfcrowd.com", "example.pdf");// create the API client instance
pdfcrowd.HtmlToPdfClient client = new pdfcrowd.HtmlToPdfClient("demo", "ce544b6ea52a5621fb9d55f8b542d14d");
// run the conversion and write the result to a file
client.convertUrlToFile("http://www.pdfcrowd.com", "example.pdf");' create the API client instance
Dim client As New pdfcrowd.HtmlToPdfClient("demo", "ce544b6ea52a5621fb9d55f8b542d14d")
' run the conversion and write the result to a file
client.convertUrlToFile("http://www.pdfcrowd.com", "example.pdf")IronPDF and PDFCrowd both provide the facility to generate PDFs from a string containing HTML. Both use only two lines of code to accomplish this task.
The following code shows that a PDF document can be rendered using an HTML input string. You can choose simple HTML, or also incorporate CSS, images, and JavaScript.
var Renderer = new IronPdf.ChromePdfRenderer();
using var PDF = Renderer.RenderHtmlAsPdf("<h1>Html with CSS and Images</h1>");
PDF.SaveAs("pixel-perfect.pdf");
// Load external html assets: images, css, and javascript.
// An optional BasePath 'C:\site\assets\' is set as the file location to load assets from
using var AdvancedPDF = Renderer.RenderHtmlAsPdf("<img src='icons/iron.png'>", @"C:\site\assets\");
AdvancedPDF.SaveAs("html-with-assets.pdf");var Renderer = new IronPdf.ChromePdfRenderer();
using var PDF = Renderer.RenderHtmlAsPdf("<h1>Html with CSS and Images</h1>");
PDF.SaveAs("pixel-perfect.pdf");
// Load external html assets: images, css, and javascript.
// An optional BasePath 'C:\site\assets\' is set as the file location to load assets from
using var AdvancedPDF = Renderer.RenderHtmlAsPdf("<img src='icons/iron.png'>", @"C:\site\assets\");
AdvancedPDF.SaveAs("html-with-assets.pdf");Dim Renderer = New IronPdf.ChromePdfRenderer()
Dim PDF = Renderer.RenderHtmlAsPdf("<h1>Html with CSS and Images</h1>")
PDF.SaveAs("pixel-perfect.pdf")
' Load external html assets: images, css, and javascript.
' An optional BasePath 'C:\site\assets\' is set as the file location to load assets from
Dim AdvancedPDF = Renderer.RenderHtmlAsPdf("<img src='icons/iron.png'>", "C:\site\assets\")
AdvancedPDF.SaveAs("html-with-assets.pdf")The following code shows that a PDF document can be generated using a string containing HTML. The HTML input string can also be used to convert to in-memory PDF, and write the resulting PDF to an Output Stream.
// create the API client instance
pdfcrowd.HtmlToPdfClient client = new pdfcrowd.HtmlToPdfClient("demo", "ce544b6ea52a5621fb9d55f8b542d14d");
// run the conversion and write the result to a file
client.convertStringToFile("<html><body><h1>Hello World!</h1></body></html>", "HelloWorld.pdf");
// run the conversion and store the result into the "pdf" variable
byte [] pdf = client.convertString("<html><body><h1>Hello World!</h1></body></html>");
// at this point the "pdf" variable contains PDF raw data and
// can be sent in an HTTP response, saved to a file, etc.
// create an output stream for the conversion result
FileStream outputStream = new FileStream("HelloWorld.pdf", FileMode.CreateNew);
// run the conversion and write the result into the output stream
client.convertStringToStream("<html><body><h1>Hello World!</h1></body></html>", outputStream);
// close the output stream
outputStream.Close();// create the API client instance
pdfcrowd.HtmlToPdfClient client = new pdfcrowd.HtmlToPdfClient("demo", "ce544b6ea52a5621fb9d55f8b542d14d");
// run the conversion and write the result to a file
client.convertStringToFile("<html><body><h1>Hello World!</h1></body></html>", "HelloWorld.pdf");
// run the conversion and store the result into the "pdf" variable
byte [] pdf = client.convertString("<html><body><h1>Hello World!</h1></body></html>");
// at this point the "pdf" variable contains PDF raw data and
// can be sent in an HTTP response, saved to a file, etc.
// create an output stream for the conversion result
FileStream outputStream = new FileStream("HelloWorld.pdf", FileMode.CreateNew);
// run the conversion and write the result into the output stream
client.convertStringToStream("<html><body><h1>Hello World!</h1></body></html>", outputStream);
// close the output stream
outputStream.Close();' create the API client instance
Dim client As New pdfcrowd.HtmlToPdfClient("demo", "ce544b6ea52a5621fb9d55f8b542d14d")
' run the conversion and write the result to a file
client.convertStringToFile("<html><body><h1>Hello World!</h1></body></html>", "HelloWorld.pdf")
' run the conversion and store the result into the "pdf" variable
Dim pdf() As Byte = client.convertString("<html><body><h1>Hello World!</h1></body></html>")
' at this point the "pdf" variable contains PDF raw data and
' can be sent in an HTTP response, saved to a file, etc.
' create an output stream for the conversion result
Dim outputStream As New FileStream("HelloWorld.pdf", FileMode.CreateNew)
' run the conversion and write the result into the output stream
client.convertStringToStream("<html><body><h1>Hello World!</h1></body></html>", outputStream)
' close the output stream
outputStream.Close()The next code for both IronPDF and PDFCrowd creates a PDF document from an ASP.NET web page.
The following code renders the ASPX web page file to PDF using IronPDF. This is a one-line code and very easy to use. More options can be added to PDF settings while rendering.
protected void Page_Load(object sender, EventArgs e)
{
IronPdf.AspxToPdf.RenderThisPageAsPdf();
}protected void Page_Load(object sender, EventArgs e)
{
IronPdf.AspxToPdf.RenderThisPageAsPdf();
}Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
IronPdf.AspxToPdf.RenderThisPageAsPdf()
End SubThe following code renders the ASPX web page file to PDF using PDFCrowd. This allows you to set complete HTTP response headers and send the result in HTTP response to be viewed in the web browser as PDF.
// create the API client instance
pdfcrowd.HtmlToPdfClient client = new pdfcrowd.HtmlToPdfClient("demo", "ce544b6ea52a5621fb9d55f8b542d14d");
// run the conversion and store the result into the "pdf" variable
byte [] pdf = client.convertUrl("https://en.wikipedia.org");
// set HTTP response headers
Response.ContentType = "application/pdf";
Response.Headers.Add("Cache-Control", "max-age=0");
Response.Headers.Add("Accept-Ranges", "none");
Response.Headers.Add("Content-Disposition", "attachment; filename*=UTF-8''" + Uri.EscapeUriString("result.pdf"));
// send the result in the HTTP response
Response.OutputStream.Write(pdf, 0, pdf.Length);
Response.Flush();// create the API client instance
pdfcrowd.HtmlToPdfClient client = new pdfcrowd.HtmlToPdfClient("demo", "ce544b6ea52a5621fb9d55f8b542d14d");

Response.Headers.Add("Content-Disposition", "attachment; filename*=UTF-8''" + Uri.EscapeUriString("result.pdf"));
// send the result in the HTTP response
Response.OutputStream.Write(pdf, 0, pdf.Length);
Response.Flush();' create the API client instance
Dim client As New pdfcrowd.HtmlToPdfClient("demo", "ce544b6ea52a5621fb9d55f8b542d14d")
' run the conversion and store the result into the "pdf" variable
Dim pdf() As Byte = client.convertUrl("https://en.wikipedia.org")
' set HTTP response headers
Response.ContentType = "application/pdf"
Response.Headers.Add("Cache-Control", "max-age=0")
Response.Headers.Add("Accept-Ranges", "none")
Response.Headers.Add("Content-Disposition", "attachment; filename*=UTF-8''" & Uri.EscapeUriString("result.pdf"))
' send the result in the HTTP response
Response.OutputStream.Write(pdf, 0, pdf.Length)
Response.Flush()The following code takes XML and converts it to PDF for IronPDF and PDFCrowd API.
C# XML to PDF directly can be a complex challenge. We have found that when converting XML to PDF in C# it is best to start with XSLT. XML may be rendered to PDF via HTML(5) using XLST transformations.
private void XMLtoPDF(string XSLT, string XML)
{
XslCompiledTransform transform = new XslCompiledTransform();
using(XmlReader reader = XmlReader.Create(new StringReader(XSLT)))
{
transform.Load(reader);
}
StringWriter results = new StringWriter();
using(XmlReader reader = XmlReader.Create(new StringReader(XML)))
{
transform.Transform(reader, null, results);
}
IronPdf.ChromePdfRenderer Renderer = new IronPdf.ChromePdfRenderer();
// options, headers, and footers may be set there
// Render our XML as a PDF via XSLT
using var PDF = Renderer.RenderHtmlAsPdf(results.ToString());
PDF.SaveAs("XMLtoPDF.pdf");
}private void XMLtoPDF(string XSLT, string XML)
{
XslCompiledTransform transform = new XslCompiledTransform();
using(XmlReader reader = XmlReader.Create(new StringReader(XSLT)))
{
transform.Load(reader);
}
StringWriter results = new StringWriter();
using(XmlReader reader = XmlReader.Create(new StringReader(XML)))
{
transform.Transform(reader, null, results);
}
IronPdf.ChromePdfRenderer Renderer = new IronPdf.ChromePdfRenderer();
// options, headers, and footers may be set there
// Render our XML as a PDF via XSLT
using var PDF = Renderer.RenderHtmlAsPdf(results.ToString());
PDF.SaveAs("XMLtoPDF.pdf");
}Private Sub XMLtoPDF(ByVal XSLT As String, ByVal XML As String)
Dim transform As New XslCompiledTransform()
Using reader As XmlReader = XmlReader.Create(New StringReader(XSLT))
transform.Load(reader)
End Using
Dim results As New StringWriter()
Using reader As XmlReader = XmlReader.Create(New StringReader(XML))
transform.Transform(reader, Nothing, results)
End Using
Dim Renderer As New IronPdf.ChromePdfRenderer()
' options, headers, and footers may be set there
' Render our XML as a PDF via XSLT
Dim PDF = Renderer.RenderHtmlAsPdf(results.ToString())
PDF.SaveAs("XMLtoPDF.pdf")
End SubThe structure of the XSLT file is as follows:

// One or more images as IEnumerable. This example selects all JPEG images in a specific folder.
var ImageFiles = System.IO.Directory.EnumerateFiles(@"C:\project\assets").Where(f => f.EndsWith(".jpg") || f.EndsWith(".jpeg"));
// Convert the images to a PDF and save it.
using var PDF = ImageToPdfConverter.ImageToPdf(ImageFiles);
PDF.SaveAs(@"C:\project\composite.pdf");
//Also see PdfDocument.RasterizeToImageFiles() method to flatten a PDF to images or thumbnails// One or more images as IEnumerable. This example selects all JPEG images in a specific folder.
var ImageFiles = System.IO.Directory.EnumerateFiles(@"C:\project\assets").Where(f => f.EndsWith(".jpg") || f.EndsWith(".jpeg"));
// Convert the images to a PDF and save it.
using var PDF = ImageToPdfConverter.ImageToPdf(ImageFiles);
PDF.SaveAs(@"C:\project\composite.pdf");
//Also see PdfDocument.RasterizeToImageFiles() method to flatten a PDF to images or thumbnails' One or more images as IEnumerable. This example selects all JPEG images in a specific folder.

' Convert the images to a PDF and save it.
Dim PDF = ImageToPdfConverter.ImageToPdf(ImageFiles)
PDF.SaveAs("C:\project\composite.pdf")
'Also see PdfDocument.RasterizeToImageFiles() method to flatten a PDF to images or thumbnailsPDFCrowd also provides the facility to convert images to PDF with a variety of options. It also provides an option to convert an image from a URL. The following code shows how to convert an image to PDF from local storage.
// create the API client instance
pdfcrowd.ImageToPdfClient client = new pdfcrowd.ImageToPdfClient("your_username", "your_apikey");
// run the conversion and write the result to a file
client.convertFileToFile("/path/to/logo.png", "logo.pdf");// create the API client instance

Dim client As New pdfcrowd.ImageToPdfClient("your_username", "your_apikey")
' run the conversion and write the result to a file
client.convertFileToFile("/path/to/logo.png", "logo.pdf")PDFCrowd is a web service that creates PDF files from other formats online. It comes with different price structures, the lowest being $11/month for a limit of 200 credits, where 1 credit equals 0.5Mb of output data. You can also sign up for a free trial. The detailed pricing can be checked on the pricing page of PDFCrowd.
IronPDF, on the other hand, is a C# PDF library. It is free for development and can always be licensed for commercial deployment. Licenses for IronPDF are available for single-project use, single developers, agencies, and global corporations, as well as SaaS and OEM redistribution. All licenses include: a 30-day money-back guarantee, one year of product support & updates, validity for dev/staging/production, and also a permanent license (one-time purchase). The Lite package starts from $749. IronPDF packages are permanent and there are no ongoing costs, while in comparison, PDFCrowd does have ongoing costs.
IronPDF does not render HTML to PDF from a remote server. It actually spins up an instance of a real standard-compliant web browser behind the scenes (without any additional software needing to be installed). The HTML is rendered with complete accuracy - and in a vector format suitable for the highest standards of commercial printing. The output is a clean and high-quality PDF. It is openly commercial with licensing and pricing details all published on the website.
PDFCrowd also converts the HTML in any given format to PDF with the highest accuracy and absolutely no downtime, as it runs on cloud servers at multiple locations. PDFCrowd is a web-based API that offers an online service to convert to PDF. Server-side API client libraries make it easy for you to use the Pdfcrowd HTML to PDF API. These libraries are available in a variety of popular server-side programming languages. Pricing details are listed on the website.
IronPDF has a slight advantage over PDFCrowd as it can work offline once installed. IronPDF is highly recommended for pragmatic coders seeking to work effectively and efficiently. Most importantly, it is time-saving. PDFCrowd can be useful when dealing with PDFs in different server-side languages. Moreover, IronPDF packages provide a lifetime license, and there are no ongoing costs, while PDFCrowd does have ongoing costs.
