Question 1

Is this PDF watermark tool free?

Accepted Answer

Yes, completely free with no account or sign-up required, and no limit on how many times you can use it.

Question 2

Is my PDF uploaded to a server?

Accepted Answer

No. The watermark is added entirely in your browser — your file is never sent anywhere.

Question 3

Where does the watermark appear on the page?

Accepted Answer

It's stamped diagonally across the center of every page, semi-transparent, so the original content stays readable underneath.

Question 4

How is this different from SignFastAi's e-signature tool?

Accepted Answer

This page just stamps a watermark onto a PDF. SignFastAi's core product lets you upload a document, place signature fields on it, and send a secure signing link to get it signed.
