PDF Watermark
Stamp text like DRAFT or CONFIDENTIAL — or your own PNG/JPG image — across every page of a PDF. Choose diagonal or horizontal placement and adjust the colour, opacity, and font size to suit the document. Everything happens in your browser via pdf-lib; nothing is uploaded to a server.
Stamp any text (DRAFT, CONFIDENTIAL, etc.) or a custom image onto every page. All processing happens in your browser — no file is uploaded.
