About adding a watermark
A watermark stamps text like DRAFT, CONFIDENTIAL, or a company name across every page — a visible signal about how a document should be treated, and a mild deterrent against casual reuse.
You set the text, position, size, rotation, and opacity, and PDFCure draws it onto each page in your browser with pdf-lib. The stamp becomes part of the page content in the new file. Because the tools run locally, the document you're marking is never uploaded.

Watermark — frequently asked questions
Can I add an image watermark instead of text?+
Yes — use the separate Image Watermark tool for a logo or photo instead of text.
Will the watermark appear on every page?+
Yes, it's applied uniformly across the whole document.
Do you upload my files to a server?+
No — every tool here processes your files entirely on your device, and nothing is uploaded to a server. The only exception is the AI tools, which send the extracted text (not the file) to Claude to do their work.
Is there a file size limit?+
There's no artificial limit we impose, but since processing happens in your browser, very large files (500+ MB or 1,000+ pages) are limited by your device's memory rather than by us.
