How to Overlay PDF Files
The first file is the document, the second is placed on it.

Click Choose PDF files and pick the document and the overlay, such as your letterhead. They are tagged Document and Overlay.

Download the result

On Top or Behind?
On top places the overlay over the page, like a transparent sheet. It suits letterheads and footers that sit in empty margins, stamps, and watermarks made in another app.
Behind places the overlay under the page content, like pre-printed paper. It suits backgrounds, certificate borders and form layouts. A background only shows where the document page is see-through, so scanned pages will cover it.
The overlay is placed as vector content, so text and logos stay perfectly sharp.

Behind
