Why there's no upload step
Watermarks help mark drafts, confidential documents, or ownership before sharing a PDF. This tool draws a semi-transparent diagonal text watermark on every page using pdf-lib, entirely in your browser.
Questions
Is my PDF uploaded anywhere?+
No. The watermark is added entirely in your browser.

Not currently — this tool supports text watermarks only.
Can I remove a watermark added by this tool?+
No built-in undo, but you can keep your original file and re-run the tool if needed.
