Convert MHTML to PDF in Java

PDF comes with many benefits, and MHTML to PDF conversion can be used for sharing, archiving, or printing web pages. In this article, you will find information about MHTML to PDF conversion scenarios and learn how to use PdfSaveOptions and MemoryStreamProvider.

MHTML to PDF by a single line of code

The static methods of the Converter class are primarily used as the easiest way to convert an MHTML file into various formats. You can convert MHTML to PDF with just a single line of code!

    // Invoke the сonvertMHTML() method to convert MHTML to PDF
    com.aspose.html.converters.Converter.convertMHTML(File.openRead(StringExtensions.concat(getDataDir(),  "sample.mht")), new PdfSaveOptions(), Path.combine(getOutputDir(), "output.pdf"));

Convert MHTML to PDF in Java

Let’s walk through the step-by-step instructions for a simple MHTML to PDF conversion scenario:

1. Load an MHTML file. You can load MHTML from a file, stream, or URL. In the example we use openRead(path) method to open and read an MHTML document from the file system.
2. Create a new PdfSaveOptions object.
3. Use the сonvertMHTML(stream, options, savePath) method of the Converter class to save an MHTML document as a PDF file. The method takes as parameters stream, options, and savePath and performs the conversion.

Please review the following Java code snippet, which shows the MHTML to PDF conversion process with step-by-step instructions:

    // Open an existing MHTML file for reading
    final  FileStream stream = File.openRead(StringExtensions.concat(getDataDir(),  "sample.mht"));
    try
    {;
    }
    finally { if (stream != null) ((IDisposable)stream).dispose(); }

    // Prepare a path to save the converted file 
    String savePath = Path.combine(getOutputDir(), "sample-output.pdf");

    // Create an instance of PdfSaveOptions
    PdfSaveOptions options = new com.aspose.html.saving.PdfSaveOptions();

    // Convert MHTML to PDF
    com.aspose.html.converters.Converter.convertMHTML(stream, options, savePath);

Convert MHTML to PDF in Java using PdfSaveOptions

With Aspose.HTML for Java, you can convert files programmatically with full control over a wide range of conversion parameters. To convert MHTML to PDF with PdfSaveOptions specifying, you should follow a few steps:

1. Load an MHTML file.
2. Create a new PdfSaveOptions object and specify the required properties. In the following example, we apply a custom page size and background color for the resulting PDF document:
   • Use the setPageSetup() method to specify the page size for the output PDF document.
   • Use the setBackgroundColor() method to set the color that fills the background.
3. Call the сonvertMHTML(stream, options, savePath) method of the Converter class.

The following Java example shows how to use PdfSaveOptions and create a PDF file with custom page size and background color:

    // Open an existing MHTML file for reading
    final  FileStream stream = File.openRead(StringExtensions.concat(getDataDir(),  "sample.mht"));
    try
    {;
    }
    finally { if (stream != null) ((IDisposable)stream).dispose(); }

    // Prepare a path to save the converted file 
    String savePath = Path.combine(getOutputDir(), "sample-options.pdf");

    // Create an instance of PdfSaveOptions. Set up the page-size and change the background color to AliceBlue 
    PdfSaveOptions options = new PdfSaveOptions();
    PageSetup pageSetup = new PageSetup();
    Page anyPage = new Page();
    anyPage.setSize(new com.aspose.html.drawing.Size(Length.fromPixels(1000),Length.fromPixels(1000)));
    pageSetup.setAnyPage(anyPage);
    options.setPageSetup(pageSetup);
    options.setBackgroundColor(Color.getAliceBlue());
