Quick Start with Aspose.HTML for .NET

Aspose.HTML for .NET is a C# library for working with web documents in server-side, desktop, and automation workflows. It lets you create and load HTML documents, inspect and edit the DOM, work with CSS and SVG, extract data, save web pages with resources, and convert HTML-related formats to PDF, XPS, DOCX, images, and Markdown.

This chapter helps you move from setup to a first working result. Start with installation and system requirements, then apply a license if you need to remove evaluation limitations, run the example project, and continue with document creation, editing, navigation, or conversion workflows.

If you are new to Aspose.HTML for .NET, install the NuGet package, confirm that your target framework is supported, run the C# examples, and try an HTML to PDF conversion before moving to advanced rendering or DOM editing tasks.

Getting Started Steps

A typical first setup has four steps: install the package, confirm the runtime environment, decide whether you need a license, and run an example. These pages cover the fastest path from a new project to a working Aspose.HTML for .NET workflow:

• Installation – install Aspose.HTML for .NET using NuGet, Package Manager Console, .NET CLI, DLLs, or MSI.
• System Requirements – check supported operating systems, frameworks, development environments, and trust level.
• Licensing – evaluate the library, request a temporary license, or apply a purchased license in C#.
• How to Run the Examples – clone or download the C# examples project and run samples locally.
• Run Aspose.HTML in Docker – configure a Linux Docker container for HTML processing and rendering.

What You Can Build with Aspose.HTML for .NET

Aspose.HTML for .NET is useful when an application needs to process web documents without relying on a browser UI. Common use cases include generating PDF reports from HTML templates, converting web pages to image or XPS output, editing HTML nodes in C#, extracting content from loaded documents, and preparing files for archiving or distribution.

The API works with HTML, XHTML, SVG, MHTML, EPUB, and Markdown as source formats and supports output workflows for PDF, XPS, DOCX, raster images, Markdown, and saved HTML resources. For a complete input and output matrix, see Supported File Formats.

Why Use Aspose.HTML for .NET?

Aspose.HTML for .NET is designed for applications that need both high-level conversion methods and lower-level document control. Its technical benefits are easiest to scan by workflow:

• Document APIs – create, load, inspect, edit, and save HTML documents through DOM-style APIs.
• Navigation and extraction – find content with selectors, XPath, traversal APIs, and document navigation tools.
• Conversion workflows – convert HTML-related sources to PDF, XPS, DOCX, raster images, Markdown, and saved HTML resources.
• Format coverage – work with HTML, XHTML, SVG, MHTML, EPUB, and Markdown in one library. For a broader overview, see the Features List.
• Deployment flexibility – use the API in server-side jobs, desktop applications, automation tools, and containerized workflows.
• Familiar concepts – build on browser concepts such as DOM, CSS, SVG, selectors, and document loading, with compact Converter methods for common tasks and lower-level options for advanced rendering.

Convert HTML to PDF in C#

A good first test is HTML to PDF conversion because it verifies that the package is installed, the main namespaces resolve, and the conversion pipeline can write output. The shortest workflow uses the Converter API with PDF save options.

To convert HTML to PDF in C#:

1. Prepare a source HTML document or HTML content.
2. Create output settings when the target format requires them, such as PdfSaveOptions for PDF.
3. Call Converter.ConvertHTML() with the source, options, and output path.
4. Save the generated PDF file.
5. Move to format-specific articles when you need page setup, fonts, streams, or rendering options.

// Convert HTML to PDF using C#

Aspose.Html.Converters.Converter.ConvertHTML(@"<span>Hello, World!!</span>", ".", new Aspose.Html.Saving.PdfSaveOptions(), "output.pdf");

After this first conversion works, continue with the full HTML to PDF in C# article for save options, page setup, streams, and related PDF workflows.

C# HTML Development Topics

Once your project is configured, choose the workflow that matches your application:

• Converting Between Formats – convert HTML, SVG, MHTML, EPUB, and Markdown to PDF, XPS, DOCX, images, and Markdown.
• Create HTML Documents – create HTML, SVG, and documents from files, URLs, streams, or strings.
• Edit HTML Documents – create, update, remove, and replace DOM nodes in C#.
• Navigate HTML Documents – use DOM navigation, CSS selectors, XPath, and traversal APIs to find content.
• Save HTML Documents – save HTML documents with linked resources, custom paths, and output handling.
• Features List – review the main Aspose.HTML for .NET capabilities and related documentation sections.
