Add Watermark to PDF
Stamp text like DRAFT or CONFIDENTIAL across every page.
How it works
Stamp text across every page — DRAFT, CONFIDENTIAL, your company name, or anything else. Set the text, colour, size, angle and how it's placed, then download the watermarked PDF.
🔒 Your file is processed entirely in this browser — it is never uploaded to a server. No signup, no watermark, no page limits.
🔒 Your document never leaves your device: unlike most online PDF tools, which upload your file to their servers, everything here runs locally in your browser. There is no upload, no account, no watermark and no page or file-count limit — so it's safe for contracts, invoices, medical records and anything else confidential.

Frequently asked questions
How do I add a watermark to a PDF?
Choose your file, type the text you want, set the placement and appearance, then download the watermarked copy. It's applied to every page.
Can I control how visible the watermark is?
Yes. Opacity, size, colour and rotation are all adjustable, so you can go from a subtle background mark to a bold overlay.
Does a watermark protect my document?
It discourages casual misuse and makes the document's status obvious, but it isn't a security feature — the mark can be removed with PDF editing software. Use real access controls if you need genuine protection.
Will your site add its own watermark?
Never. The only mark on your PDF is the text you choose, with no branding, and no signup required.
