PeachPDF

Peach PDF is a pure .NET HTML -> PDF rendering library. This library does not depend on Puppeter, wkhtmltopdf, or any other process to render the HTML to PDF. As a result, this should work in virtually any environment where .NET 8+ works. As a side benefit of being pure .NET, performance improvements in future .NET versions immediately benefit this library.

PeachPDF Requirements

• .NET 8

Note: This package depends on PeachPDF.PdfSharpCore and various SixLabors libraries. Both have their own licenses, but the end result is still open source

Installing PeachPDF

Install the PeachPDF package from nuget.org

Using PeachPDF

Simple example

Simple example to render PDF to a Stream. All images and assets must be local to the file on the file system or in data: URIs

PdfGenerateConfig pdfConfig = new(){
  PageSize = PageSize.Letter,
  PageOrientation = PageOrientation.Portrait
};

PdfGenerator generator = new();

var stream = new MemoryStream();

var document = await generator.GeneratePdf(html, pdfConfig);
document.Save(stream);

Rendering an MHTML file

You can generate PDF documents using self contained MHTML files (what Chrome calls "single page documents") by using the included MimeKitNetworkAdapter

PdfGenerateConfig pdfConfig = new(){
  PageSize = PageSize.Letter,
  PageOrientation = PageOrientation.Portrait
  NetworkAdapter = new MimeKitNetworkAdapter(File.OpenRead("example.mhtml"))
};

PdfGenerator generator = new();

var stream = new MemoryStream();

// Passing null to GeneratePdf will load the HTML from the provided network adapter instance instead
var document = await generator.GeneratePdf(null, pdfConfig);
document.Save(stream);

Rending HTML from a URI

You can also render HTML from the Internet to a PDF

Note: a future version will be required in order to have the base URI automatically detected, so make sure the document has a tag set for images, styles, and links to resolve correctly

HttpClient httpClient = new();

PdfGenerateConfig pdfConfig = new(){
  PageSize = PageSize.Letter,
  PageOrientation = PageOrientation.Portrait
  NetworkAdapter = new HttpClientNetworkADapter(httpClient, new Uri("https://www.example.com"))
};

PdfGenerator generator = new();

var stream = new MemoryStream();

// Passing null to GeneratePdf will load the HTML from the provided network adapter instance instead
var document = await generator.GeneratePdf(null, pdfConfig);
document.Save(stream);
