Online PDF workflow

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.

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?

Core PDF actions run in the browser whenever possible. When a conversion needs a worker, files are processed through encrypted temporary storage and cleaned automatically.

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.
