When I compare these PDF files, I get this output.pdf (141.9 KB). However, your output PDF is different that you shared as an image. Could you please share the sample code to get the PDF just like yours?

Are you using GroupDocs.Conversion to convert the PDF files to Images? If not, please share the original source and target images files (not the PDFs).
