How do I add a watermark to a PDF?
Type the text — "CONFIDENTIAL", "DRAFT", the recipient's name — then set its angle, size and transparency. It is applied to every page.
Watermark
Stamp text or a logo on every page.
Mark a document as confidential, draft or copy. A watermark is a visual mark: to remove information for good, use redaction instead.

Common questions
Are my files uploaded to the internet?
No. This tool runs entirely in your browser: the document is opened on your device, processed there, and never sent anywhere. You can even go offline once the page has loaded.
Does a watermark stop the document being copied?
No. It discourages sharing and marks the origin, but it does not protect: someone who knows how can remove it. To restrict access you need a password.
Is it free, and do I need an account?
Free and unlimited, with no account and no sign-up. This tool costs us nothing because it runs on your machine, so we have no reason to ration it.
