Stamp a text watermark (CONFIDENTIAL, DRAFT, your name…) across every page of a PDF. Runs entirely in your browser; the PDF is never uploaded.

Optimize for your platform

Sådan fungerer det

Stamping a watermark (CONFIDENTIAL, DRAFT, a name) across a PDF usually means Acrobat or an upload. This draws it on with pdf-lib, in your browser.

  1. 1
    You drop in a PDF
    The page count is read locally with pdf-lib — nothing is uploaded.
  2. 2
    You set the watermark
    Type the text and choose a layout (diagonal, horizontal, or tiled across the page), colour, opacity, and size.
  3. 3
    It's drawn on every page
    pdf-lib draws the semi-transparent, rotated text on each page over the existing content.
  4. 4
    You download the result
    The watermarked PDF is offered for download with the original content intact beneath the watermark.

Mark a document as confidential or draft without sending it to a server — everything is stamped on your device.
