Watermark a PDF
Stamp custom text across a PDF — centered, top, bottom, or tiled.
Add a text watermark to every page. Choose position (centered, top, bottom, or tiled across the page), font size, color, and opacity. Useful for draft stamps, confidentiality markers, or personal IDs.

Your file stays on your device
Every other “online PDF tool” uploads your document to a server. SealedPDF does the work in your browser using pdf-lib and pdf.js — you can verify this yourself by opening DevTools and watching the Network tab while you process a file.
