About PDF Stamp
PDF Stamp overlays the first page of a stamp PDF on top of every page of your main document at a chosen opacity. Unlike the text-based Watermark tool, PDF Stamp accepts a PDF as the stamp — so you can use a custom logo, a pre-designed stamp image (CONFIDENTIAL, DRAFT, APPROVED), or any graphical mark created in design software. The stamp is placed at full page size with transparency control.
How to use PDF Stamp
Upload both PDFs
Upload the main PDF first, then the stamp PDF (the image/mark to overlay). Both files go in the same upload area.
Set opacity
Choose how transparent the stamp should be: 25% for subtle, 50% for balanced, 75–100% for bold stamps.
Download
Download the stamped PDF with the overlay applied to every page.
