or click to browse — your file never leaves your device
Stamp a text watermark across your PDF — “CONFIDENTIAL”, “DRAFT”, a copyright notice or your company name. Control the opacity, rotation and size, or tile the watermark across each page. The watermark is applied in your browser, so your document is never uploaded.
Frequently asked questions
How do I add a watermark to a PDF?
Open the PDF, type the watermark text, then adjust opacity, rotation and size until it looks right — a light diagonal stamp is the classic style. Download the watermarked file when you are done.
Can I tile the watermark across the whole page?
Yes. Tiling repeats the text in a pattern across each page instead of a single stamp, which makes the watermark harder to crop out and is common for protecting proofs and drafts.
Is my file uploaded to add the watermark?
No. Watermarking runs entirely in your browser — a real advantage when the documents being marked are exactly the confidential ones you would not want on someone else’s server.
Does a watermark stop people copying my document?
It deters casual reuse and clearly labels a document’s status, but it is not security — a determined person can still extract content. For real protection, combine watermarking with access controls on how the file is shared.
