Frequently Asked Questions

Is my PDF uploaded anywhere?

No. The watermark is added inside your browser — no server, no upload.

Where will the watermark appear?

In the centre of every page, diagonally — so it does not get in the way of reading, but the document stays protected.

Can the watermark be removed?

Honestly: this is a mark, not a security lock. Someone who knows how to edit a PDF can remove it — but it is enough for everyday sharing.
