完全ガイド: スタンプを追加

Adding stamps to PDF documents is a professional way to mark document status, add approval indicators, or place official stamps on digital documents. iLoveDoc's Add Stamp tool lets you place pre-designed stamps (like "Approved," "Rejected," "Draft," "Confidential") or custom stamp images on any page of your PDF. Stamps are placed as visual overlays that become a permanent part of the document, making them visible in all PDF viewers and when printing. You can position stamps precisely, resize them, and adjust their opacity. This is commonly used in business workflows where documents pass through approval chains, in legal settings where documents need official stamps, and in educational contexts where papers need grading marks. All processing happens locally in your browser.
