PDF Overlay

    Free Tool

    Overlay a second PDF across pages of a base PDF (useful for template layers and draft marks).

    Privacy first: this tool runs fully client-side. If you do not trust us, turn off your internet, do your task, then close this browser — that ensures 100% offline processing.

    Adjust opacity to control overlay strength across all pages.

    When overlay has fewer pages, pages repeat in a loop over the base document.
