We have tested your scenario with the latest version 18.2 of Aspose.PDF for .NET API. This is the output PDF: Output.pdf (274.7 KB). Kindly highlight the problematic area with the help of a snapshot.

Hello Imran,

Thank you for reply.

In your “OUTPUT” file you can check from the third page which is actually my another PDF that need to be merge with first one,

In Third page, the contents are going touch to the right side of the page. where i need to set margin for that so it looks better

here i am attaching my second PDF that need to be merge where it looks good but after merging the contents are cutting down

SAIC-A-2007.pdf (136.4 KB)
