PDF Watermark
Add a text watermark to every page of a PDF — confidential drafts, client materials, anything. Choose the text, font size, opacity, rotation and color, then stamp it centered or tiled across the page. Chinese and other scripts render perfectly. Everything is processed locally with pdf-lib, so your document never leaves your device.
🔒 Privacy: all processing happens locally in your browser. Nothing is uploaded.
