HTML Converter – Convert HTML in Java

Use the HTML Converter guides when the source is an HTML file, HTML string, stream, or URL. Aspose.HTML for Java converts HTML to PDF, XPS, DOCX, JPG, PNG, BMP, TIFF, GIF, MHTML, and Markdown.

Most HTML conversion workflows use an HTMLDocument, save options for the target format, and the convertHTML() methods of the Converter class. Ideal for generating printable documents, thumbnails, or web‑friendly files directly from Java applications.

How HTML Conversion Works

  1. Install Aspose.HTML for Java.
  2. Load HTML with HTMLDocument, or pass supported source content directly to a convertHTML() overload.
  3. Create save options for the required output format, such as PdfSaveOptions, ImageSaveOptions, DocSaveOptions, XpsSaveOptions, MHTMLSaveOptions, or MarkdownSaveOptions.
  4. Call Converter.convertHTML() with the source, save options, and output path.

The following Java example loads nature.html, selects PNG with ImageSaveOptions, and converts the document to nature-output.png.

 1// Convert HTML to PNG in Java
 2
 3// Initialize an HTML document from a file
 4HTMLDocument document = new HTMLDocument("nature.html");
 5
 6// Initialize ImageSaveOptions
 7ImageSaveOptions options = new ImageSaveOptions(ImageFormat.Png);
 8
 9// Convert HTML to PNG
10Converter.convertHTML(document, options, "nature-output.png");
