Type your text, set opacity and rotation, pick a position or tile it across the page.
Download the marked copy
Click Add watermark. Every page carries your stamp, and the file downloads instantly.

When to watermark PDF pages
Review copies marked DRAFT before they circulate, contracts stamped CONFIDENTIAL, portfolios signed with the owner's name, training materials labeled INTERNAL. A watermark states status at a glance and discourages casual reuse.
Watermarking happens locally — private documents stay private.

Frequently asked questions
Can I watermark with Chinese, Japanese, or Korean text?
Yes — full CJK support is a headline feature. Characters render correctly, including full-width punctuation.
How do I keep the watermark from hiding the content?
Lower the opacity slider until the text is present but unobtrusive. 20-30% works for most documents.
Can I place different text on different pages?
The watermark applies uniformly to the whole document. For per-page text, split the PDF first, watermark each part, then merge.
Does a watermark prevent copying?
A visible watermark deters, it doesn't prevent. For actual restrictions (copying, printing), use Protect PDF to set document permissions.
Can I add an image logo as watermark?
This tool stamps text watermarks. Image watermarking is on the roadmap.
Is the watermarked file uploaded anywhere?
No. The watermark is rendered and stamped locally in your browser.
