About the Add Watermark to PDF tool
Add Watermark lets you stamp text such as CONFIDENTIAL, DRAFT, SAMPLE or your company name across the pages of a PDF. Control the font size, color, opacity, rotation and position — centered, in a corner or tiled across the page — and apply it to all pages or a chosen range.
The watermark is drawn into the PDF directly in your browser, so your document is never uploaded. Original content stays sharp and selectable underneath.
100% private: your file never leaves your device — it is processed in your browser. No upload, no storage, no account.
