Can I control how visible the watermark is?

Yes — an opacity slider goes from a faint stamp to a bold, hard-to-miss one. The size adjusts automatically so long text still fits on the page.

Does the watermark apply to every page?

Yes, the same text is stamped diagonally across every page of the document in one pass.

Can I remove the watermark afterward?

Not from this tool — it's drawn permanently into the page content, the same as it would be from any PDF watermarking tool. Keep your original file if you need an unmarked copy.
