Before you start
Prepare your PDF and a transparent stamp image. Decide which page and area should receive the mark. Keep the stamp away from important clauses, signatures and page numbers, and retain an unchanged original document.
How to use it
Open the PDF stamping tool and upload the document. Add your stamp and select the page you need. Adjust its position, size, rotation and opacity, then download the result. Reopen the saved PDF and inspect the affected pages before sharing it.
