PDF Overlay Two Documents

Overlay a stamp, letterhead or watermark PDF on top of another PDF, page by page.

Base PDF:

Overlay PDF:

Upload both files, then overlay.

How to use

Upload the base PDF and the overlay PDF (letterhead/stamp). The overlay is drawn onto every base page.

How do pages line up?

Each overlay page is scaled to its base page; a single-page overlay repeats on all pages.

Can I adjust opacity?

The overlay keeps its own design; flatten transparency in the source for lighter marks.
