Como funciona

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