The exception “Operation is not valid due to the current state of the object” during the conversion from MHT to PDF can occur due to various reasons, such as issues with the input file or the way the conversion is being executed. Here are some steps you can take to troubleshoot and resolve this issue:

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

  2. Use Proper File Handling: Make sure you are correctly managing the file streams. Here’s a sample code snippet for converting MHT to PDF using Aspose HTML in Java:

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

public class MHTMLToPDFExample {
    public static void main(String[] args) {
        try (java.io.FileInputStream fileInputStream = new java.io.FileInputStream("path/to/your/sample.mht")) {
            PdfSaveOptions options = new PdfSaveOptions();
            options.setJpegQuality(100);
            String outputFile = "path/to/your/output.pdf";
            Converter.convertMHTML(fileInputStream, options, outputFile);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

  3. Update the Library: Ensure that you are using the latest version of the Aspose HTML library. Sometimes, bugs are fixed in newer releases, so updating might 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 trying these steps, consider sharing the specific MHT file that is causing the issue for further analysis.
