HtmlRendererCore: Convert HTML to PDF in .NET Core

Overview

HtmlRendererCore brings HTML-to-PDF generation to .NET Core applications by combining a partial port of HtmlRenderer with PdfSharpCore. It is aimed at developers who need to create PDF documents from HTML within a C# project rather than use a separate conversion service.

The project is a fit for straightforward PDF generation, but it does not claim complete HTML-rendering coverage. Its maintainers describe broader rendering support as future work.

Key Features

• Generates PDF documents from HTML strings.
• Uses PdfSharpCore to create PDFs.
• Supports specifying a page size, such as A4.
• Allows generated PDFs to be saved to a stream and encoded as Base64.
• Provides a .NET Core-oriented partial port of HtmlRenderer.

Use Cases

• A .NET Core developer needs to generate a basic PDF from HTML in an application.
• A service needs to return a generated PDF as a file or stream.
• An application needs to encode a generated PDF as Base64 for transfer or storage.

Getting Started

Use PdfGenerator.GeneratePdf with the HTML content and a page size:

var pdf = PdfGenerator.GeneratePdf(html, PdfSharpCore.PageSize.A4);

See the repository README for additional usage details. The project uses PdfSharpCore.

Alternatives

• QuestPDF: QuestPDF builds PDFs with a fluent component API rather than converting HTML, so it suits structured documents instead of HTML-based layouts.

Considerations

• This is a partial port, so it may not support all HTML-rendering behavior available in the original HtmlRenderer.
• The README identifies support for more advanced HTML rendering as future work.
• PDF generation depends on PdfSharpCore; check its documentation and compatibility for your project before adopting this library.
