Overlays your own text or logo across every page — with no third-party branding added.
About this tool
Our free add-watermark tool stamps a custom text or logo watermark across every page of a PDF. It is what you need to mark a document “CONFIDENTIAL” or “DRAFT”, brand a proposal with your company logo, or protect work you are sharing for review. Type any text or upload a PNG/JPG logo, then control its opacity, position, and rotation — or tile a text watermark diagonally across the whole page. The key difference from free online watermarkers is that GetFreeToolsAI never adds its own branding: only the watermark you create appears, with no daily limits. Everything runs locally in your browser using pdf-lib, so your document is never uploaded to a server and your confidential files stay on your device. It works in Chrome, Firefox, Safari, and Edge with no installation and no signup, ever.
