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.

• .NET 8

Note: This package depends on PeachPDF.PdfSharpCore which has its own license, but the end result is still open source

Install the PeachPDF package from nuget.org

dotnet add package PeachPDF

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);

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

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

PdfGenerator generator = new();

var stream = new MemoryStream();

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

You can also render HTML from the Internet to a PDF

HttpClient httpClient = new();

PdfGenerateConfig pdfConfig = new(){
  PageSize = PageSize.Letter,
  PageOrientation = PageOrientation.Portrait,
  NetworkLoader = new HttpClientNetworkLoader(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 loader instance instead
var document = await generator.GeneratePdf(null, pdfConfig);
document.Save(stream);

Note that loading images using relative paths will default to the local file system unless an HttpClientNetworkLoader (or custom RNetworkLoader) with an appropriate BaseUri is provided, or if the HTML has a <base> element with an href set. Images will need to be in the current working directory when using the default loader.

By default, PeachPDF uses Segoe UI. Segoe UI is installed by default on Windows, but isn't necessarily available on other platforms. You can remap Segoe UI to another font using

PdfGenerator generator = new();
generator.AddFontFamilyMapping("Segoe UI","sans-serif"); // or any other system installed font

The recommended way to install custom fonts is to install them into your operating system. PeachPDF by default picks up TrueType fonts from the operating system (%SystemRoot%\Fonts and %LOCALAPPDATA%\Microsoft\Windows\Fonts on Windows, /Library/Fonts on Mac, and /usr/share/fonts, /usr/local/share/fonts/, and $HOME/.fonts on Linux)

You can also add a font at runtime by loading the font into a Stream, and then using the AddFontFromStream API:

PdfGenerator generator = new();
await generator.AddFontFromStream(fontStream); // Supports TrueType (TTF), CFF, WOFF, and WOFF2 formats

Web fonts loaded via @font-face are also supported.

We support TrueType, CFF, WOFF, and WOFF2 font formats.
