Visible, not tamper-proof

The watermark is drawn on each page as text. It deters casual copying, but anyone with a PDF editor can remove it, so it is not a security control.

Frequently asked questions

Is my PDF uploaded anywhere?

No. The PDF is opened and processed in your browser. It never leaves your device, which makes these tools safe for contracts, bank statements and medical records.

Does it work with password-protected PDFs?

PDFs that need a password to open cannot be processed. Open the file in your PDF reader with the password and save or print an unprotected copy first.
