About this tool
Overlay a watermark, letterhead, or template PDF onto every page of another PDF with full control over position and opacity.
PDF Overlay lets you stamp one PDF on top of another, compositing content from two documents into a single file. It's perfect for watermarking pages with a logo or confidentiality label, adding a letterhead or footer to every sheet, placing a signature page onto a contract, or affixing approved-stamp overlays to templates. You choose a base PDF and an overlay PDF, then control exactly how the overlay is placed: stretched to fill the page, or fitted and positioned at the center, corners, or edges—with adjustable opacity so the stamping blends naturally with the underlying document.
Overlay pages can be mapped to your base document in two ways: paired to matching page numbers, or repeated cyclically across every page. The result is a standard PDF that opens in any reader, produced entirely within your browser for complete privacy.
