✓ Custom text — Type any watermark — CONFIDENTIAL, DRAFT, your name, anything.

Yes. The watermark is automatically applied to every page in the PDF.

Watermarks added this way are part of the PDF content and cannot be easily removed. Choose carefully before downloading.

Any text — CONFIDENTIAL, DRAFT, DO NOT COPY, your organisation name, date, or any custom text.

The tool attempts to open protected PDFs. Owner-restricted PDFs may work; user-password PDFs require the password to be removed first.
