Frequently asked questions

Can I change the opacity?

Does the watermark cover content?

It is drawn semi-transparently on top, so underlying text stays readable.

Confirm metadata removal

This edits document properties only; page content, links, annotations and forms are preserved where the PDF engine supports it. Some metadata structures (for example extended XMP written by other editors) may not be fully removed. Your original file is not changed — a separate cleaned PDF is created.
