HTML Conversion API for .NET
Convert HTML, XHTML, MHTML, EPUB, Markdown, and SVG to PDF, DOCX, XPS, and images in C#
Convert HTML and Web Formats in C#
Aspose.HTML for .NET is a C# library for converting HTML and related web formats in .NET applications. Use it to render HTML, XHTML, MHTML, EPUB, Markdown, or SVG to PDF, DOCX, XPS, and raster image formats without automating a browser.
For HTML conversion, the API accepts a file, URL, stream, string, or an in-memory HTMLDocument . The Converter class performs the conversion, while format-specific save options control the result.
The basic workflow has three steps:
- Load the source into an
HTMLDocument, or pass a supported source directly to the converter. - Create an output options object such as
PdfSaveOptions,DocSaveOptions,XpsSaveOptions, orImageSaveOptions. - Call Converter.ConvertHTML() and specify the output file or stream.
Start with HTML to PDF , HTML to DOCX , HTML to image , or choose another source and output format below.
