Add Stamp to PDF lets you place an approval mark, signature image, date stamp, or custom graphic anywhere on a page — commonly used to mark documents as "Approved," "Received," or "Paid," or to add a scanned signature to a contract without printing it first. Upload your image or choose a stamp style, position it exactly where you need it on the page, resize as needed, and save. It's a faster alternative to printing, physically stamping, and re-scanning a document, and works the same way across contracts, invoices, and internal paperwork.
