Watermark PDF
Add a text watermark to every page — centered or tiled, with adjustable opacity, size, angle, and color. Live preview, 100% in your browser.
Overview
Watermark PDF stamps a text watermark across every page of a PDF, entirely in your browser. Type your text — like CONFIDENTIAL or DRAFT — and choose centered or tiled placement, then fine-tune opacity, font size, rotation, and color while a live preview of the first page updates instantly. The watermark is drawn as real text on top of the original content, so your existing text stays selectable underneath. Everything runs client-side with pdf-lib, so your document never leaves your device.
