The exception “Value of ‘value’ is invalid” during the conversion from MHT to PDF using Aspose.HTML can occur due to various reasons, such as issues with the input MHT file or the configuration of the conversion options.

To troubleshoot this issue, you can follow these steps:

  1. Check the Input File: Ensure that the MHT file you are trying to convert is not corrupted and is properly formatted. You can try opening it in a web browser to verify its content.

  2. Use Proper Conversion Code: Make sure you are using the correct code for the conversion. Here is a sample code snippet that demonstrates how to convert an MHT file to PDF using Aspose.HTML:

    import com.aspose.html.saving.PdfSaveOptions;
import com.aspose.html.converters.Converter;

public class MHTMLToPDFConverter {
    public static void main(String[] args) {
        try (java.io.FileInputStream fileInputStream = new java.io.FileInputStream("path/to/your/input.mht")) {
            // Initialize PdfSaveOptions
            PdfSaveOptions options = new PdfSaveOptions();
            options.setJpegQuality(100); // Set JPEG quality if needed

            // Convert MHTML to PDF
            Converter.convertMHTML(fileInputStream, options, "path/to/your/output.pdf");
        } catch (Exception e) {
            e.printStackTrace(); // Handle exceptions appropriately
        }
    }
}

  3. Update Library: Ensure that you are using the latest version of the Aspose.HTML library. Sometimes, bugs are fixed in newer releases, so updating to the latest version may resolve the issue.

  4. Review Documentation: Check the official Aspose documentation for any specific requirements or limitations regarding MHT to PDF conversion.

If the problem persists after following these steps, consider reaching out to Aspose support with details about your input file and the exact error message for further assistance.

Feel free to share any additional information or error logs that might help in diagnosing the issue.
