Stamp a text watermark on every page — tile it diagonally across the page, center it, or drop it in a corner. Adjust size, opacity and angle.
Mark a draft, brand a proof, or stop a confidential file from being passed around unnoticed. This stamps your text onto each page — faint enough to read through, clear enough to see. Choose a diagonal tile across the whole page, a single centered mark, or a discreet corner label.
It renders with pdf-lib entirely in your browser, so the document never leaves your machine. ☕
It is drawn into the page content, so it is not a separate layer a viewer can simply switch off. Anyone determined enough can edit a PDF, so treat it as a deterrent and a label rather than copy protection.
This version stamps text. For a logo, export your mark as a PDF or image and place it with a desktop editor, or use the text watermark with the company name for a similar effect.
At low opacity it sits lightly over the page, which is what you want for DRAFT or CONFIDENTIAL. Increase opacity only if you need it clearly visible in screenshots.
Enter 1 in the page range box. Leaving it empty or typing "all" stamps every page.
The page itself needs to load once, but processing is fully local. No file is uploaded, so you can safely use it for contracts and drafts.
