Convert HTML to PDF in Java

The following example uses HTMLDocument to load an HTML file, PdfSaveOptions to define PDF output, and Converter.convertHTML() to create document.pdf.

Load document.html into an HTMLDocument.
Create a PdfSaveOptions instance with default settings.
Call Converter.convertHTML() with the document, options, and output path.

1import com.aspose.html.HTMLDocument;
2import com.aspose.html.converters.Converter;
3import com.aspose.html.saving.PdfSaveOptions;
4
5HTMLDocument document = new HTMLDocument("document.html");
6PdfSaveOptions options = new PdfSaveOptions();
7
8Converter.convertHTML(document, options, "document.pdf");

After the code runs, document.pdf contains the rendered content of document.html. For a detailed workflow and conversion settings, see Convert HTML to PDF in Java.
