Hello @ananth97 ,
We sincerely apologize for the situation. In order to assist you with this issue, we need more information. Could you please provide us with the code sample you are using, a test file for conversion, and specify the version of GroupDocs.Conversion you are working with?

Thank you for providing the information. We have registered this issue in our system under the number CONVERSIONNET-7566. We will get back to you with the results after further investigation.
After reviewing your usage example, we are not entirely sure what page dimensions you are trying to set for PageWidth and PageHeight. Do you have specific requirements for page size, margins, etc., or are the default values sufficient for you? You could simply use PageSize = PageSize.A4, for example, if that works for you.
We noticed that you are calculating page dimensions before conversion, and it’s possible that the values passed to PageWidth and PageHeight are too small. This issue occurs when setting dimensions to 150px or less. If this is required by your use case, please clarify your requirements.
We look forward to your response.
