Stamp a text watermark like DRAFT or CONFIDENTIAL — or add page numbers — across every page of a PDF, right in your browser.
Short answer
To watermark a PDF, type your text (e.g. DRAFT), choose your file, and download — the text is stamped diagonally across every page at a light opacity. Prefer numbers? Switch to page numbers. Free, and nothing is uploaded.
No. The watermark or page numbers are stamped in your browser and the file is never sent to a server — safe for confidential documents.
Yes. Type any text and it's stamped diagonally across every page at a light opacity, so the content stays readable underneath.
Yes — switch to page-number mode and each page gets a number (e.g. '1 / 12') at the bottom.
No. The text is drawn as a vector layer over the existing pages; the original content is untouched.
Yes — no signup, no watermark of ours, and it runs entirely in your browser.
Your PDF is stamped entirely in your browser and is never uploaded. Provided free and ad-supported, without warranty.
