Stamp a watermark on every PDF page — set text, logo, opacity and position.

Add a text or image watermark to every page of a PDF. Set opacity, position and font size. Free online watermark tool — no sign-up, no account needed. No account, no watermark, runs in your browser.

Stamp 'CONFIDENTIAL', 'DRAFT' or a custom logo on every page at once.

Adjust opacity and position so the watermark doesn't obscure the content.

Apply the watermark in the browser and download — no upload to a cloud service.

Is Watermark free to use?

Yes. Watermark is free for personal use, does not require an account and does not add a watermark to your exported PDF.

Are my files safe in Watermark?

Current live tools process files in the browser. Some tools use local browser workers or WebAssembly modules, but the document still stays on your device.

Can I use Watermark on mobile?

Yes. The tool works in modern mobile and desktop browsers, so you can upload, adjust and download PDFs without installing a desktop app.
