Stamp text like DRAFT or CONFIDENTIAL across a PDF, in your browser.

Drag it in. It is processed on your own computer.
Text, position, angle, size and how transparent it should be.
The original pages are untouched underneath.
The watermark is appended as an extra layer over the existing content. Text stays selectable, embedded fonts stay intact, and image quality is unchanged because nothing is decoded and re-encoded.
Uses a proper PDF graphics state rather than drawing pale grey text. The watermark genuinely sits over the page, so what is underneath stays readable at any opacity.
Text longer than the sheet is scaled down instead of running off the edge, and pages of different sizes or with a stored rotation each get a watermark that is centred and upright for the reader.
Add a text watermark to a PDF — diagonally across the middle by default, or in any corner — with control over size, angle, shade and transparency, and the option to stamp only certain pages. The existing page content is left exactly as it was: the watermark is appended as a separate layer, so text stays selectable, fonts stay intact and nothing is re-encoded. Real transparency is used rather than a pale grey imitation, so the watermark sits over the page without hiding it. The file is processed entirely in your browser and is never uploaded.
