Watermark a PDF without the upload

Most “free” watermark tools push your document to a server before they stamp it , a problem when the file is a contract, a draft or anything confidential. This one does the entire job on your own device. Type any text , CONFIDENTIAL, DRAFT, a client name , then dial in the opacity, rotation, colour and position so it reads clearly without hiding your content. Place it centered on the diagonal, tiled across the whole page, or tucked into any of the four corners, and target only specific pages with a range like 1-3, 5. Turn on page numbers in three formats at any edge, watch the live preview of page one update as you go, and download a clean stamped PDF in one click. Instant, fully private, and offline-capable once the page has loaded. No sign-up, no size limits, free forever.

§ 04 · faq

Frequently asked questions.

Is the PDF Watermark & Page Numbers tool free?
Yes , completely free for everyone, including page numbers. No sign-up, no account and no usage limits.
Is it private? Is my PDF uploaded anywhere?
No upload, ever. The whole thing runs in your browser on your own device , your PDF never leaves your computer and nothing is sent to a server.
Does it work offline?
Yes , once the page and its PDF libraries have loaded, everything happens locally, so it keeps working without a connection.
Can I watermark only specific pages?
Yes. Use the Apply to pages field and enter a range like 1-3, 5 to stamp only those pages. Leave it blank to apply the watermark to every page.
What watermark positions are available?
You can place the watermark centered diagonally, as a tiled repeat across the page, or in any of the four corners (top-left, top-right, bottom-left, bottom-right).
Will the watermark cover my text or make it hard to read?
You control it. Lower the opacity so the watermark sits lightly behind your content, adjust the rotation and font size, and use the live preview of page one to get the balance right before you download.
