Before you start
- The first file is the base and the second goes on its pages — swap them with the arrows.

How to do it
Add your file
Add two PDFs: the base document first, then the one that goes on top — a letterhead, a stamp sheet, a background.
Set it up the way you want
Choose which page of the top file to use, how see-through it should be, and whether to fit it to the base page.
Download the result
Download the combined file. Both layers are real page content, so text from either one stays selectable.
Questions about Overlay PDF
- Does the file order matter?
- Yes, and it is the whole thing. The first file is the base and the second is drawn over it. If your letterhead came out underneath the text, swap the two files and run it again.
- What if the two documents have different page counts?
- Pick a single page of the top file and it repeats over every base page — that is how a letterhead or a stamp works. Leave it on the matching-page setting and page one covers page one, page two covers page two, which is how you overlay two versions of the same document.
- Why not just use watermark or stamp?
- Because those draw text or a picture. This one puts a whole PDF page on top, which is what a designed letterhead or a pre-printed form actually is — vector artwork, real fonts, several elements placed exactly. Rebuilding that as a text stamp never quite matches.
