How to Convert HTML in C#

This article gives information on the list of supported HTML conversions and how to perform them using the Converter class that groups all low-level conversion operations in a single class to make them comfy and easy to use.

Any conversion you want to perform involves loading an HTML document and saving it in the supported format. It can be different scenarios, but it can be made with a few required steps:

  1. Load an HTML document into a Document object using one of HTMLDocument() constructors. You can load HTML from a file, HTML code, stream, or URL.
  2. Create a Save Options object.
  3. Invoke one of the ConvertHTML() methods and pass the required parameters to it.

Please take a look over the following C# code snippet that shows the HTML to PNG conversion using the ConvertHTML(document, options, savePath) method.

 1using System.IO;
 2using Aspose.Html;
 3using Aspose.Html.Converters;
 4using Aspose.Html.Saving;
 7    // Initialize an HTML document from a file
 8    using var document = new HTMLDocument(Path.Combine(DataDir, "nature.html"));
10    // Initialize ImageSaveOptions 
11    var options = new ImageSaveOptions();
13    // Convert HTML to PNG
14    Converter.ConvertHTML(document, options, Path.Combine(OutputDir, "nature-output.png"));

The ConvertHTML() method takes as parameters document, options, and savePath and performs the operation. Note: You need to specify the path to the output file in your local file system (savePath). Also, for HTMLDocument(address) constructor, you need to provide the path to a source HTML file on your local file system.
