Add a Watermark or Stamp to a PDF
PDF Watermark & Stamp overlays custom text — a company name, "CONFIDENTIAL", a checkprint chop, or a date — across every page of a PDF. It’s a quick way to mark a document as a draft, claim authorship, or add a visible security marking before sharing it externally.
How to use
- Upload the PDF you want to stamp.
- Type your watermark text and adjust its position, size, rotation, and opacity.
- Click "Apply Watermark" and download the stamped PDF.
Common use cases
