Frequently asked questions

Is this tool really free?

Yes. Every tool on this site is free, with no account or sign-up required.

Can I remove the watermark later?

The watermark becomes part of the downloaded PDF, so keep your original file if you may need a clean copy.

A watermark that says whose it is

Watermark stamps a text watermark, such as DRAFT or CONFIDENTIAL, over every page of your PDF. You type the text and control the size, color and opacity, then download the stamped file. Everything runs in your browser.

Visible but not in the way

Opacity is the key control. A light mark shows ownership without hiding the content underneath. Size and color set how prominent the mark is. Check the preview at full size before you download.

A watermark is not protection

A watermark marks a document, but it does not stop copying or reading. For real access control, use Protect with a password, which encrypts the file with AES-256.

More questions

Can I use my own words?

Yes. Type any watermark text.

Can I change how strong it looks?

Does it change the original text?
