Hi, We cant share the code snippet and pdf document. We would like to explain the issue what we are facing. We have aspose license and we use aspose.word dl. We convert the word document to pdf by just replacing .docx to .pdf extension. While we are converting we are getting blank pages in the pdf, we need to edit the pdf and delete those blank pages. We are not able to edit the pdf file in the code. So need your help on this

In order to delete pages from PDF or edit PDF in any manner, you need to use Aspose.PDF API. Please check below code example to delete the pages from PDF:

Furthermore, if input Word document already has empty/blank pages, you can also delete them before converting to PDF. Please check below post:;

In case there are no blank pages in the input Word document and still you are noticing them in the generated PDF, this issue may be related to Aspose.Words and we request you create an inquiry in Aspose.Words Support Forum where you will be assisted accordingly.

Are you saving the document before deleting the empty/blank pages? Please try to re-initialize the document object before performing this operation and in case you still face any issues, please share a sample PDF with us so that we can further test it in our environment and address accordingly.
