Frequently asked questions

How do I add a confidential watermark to a PDF?

Upload your PDF, type 'CONFIDENTIAL' in the watermark text field, adjust opacity to 30-40% for a clear but not overwhelming mark, and download. It takes about 10 seconds.

Does a confidential watermark have legal significance?

While a watermark alone doesn't create legal protection, it demonstrates intent to keep the document confidential. Combined with NDAs or confidentiality agreements, it strengthens your legal position.

Can I use different text like 'PRIVATE' or 'RESTRICTED'?

Absolutely. The text is fully customizable. Use 'CONFIDENTIAL', 'PRIVATE', 'RESTRICTED', 'INTERNAL USE ONLY', or any classification that fits your needs.

Will the confidential watermark appear when printed?

Yes. The watermark is embedded in the PDF content and will appear on printed copies, providing consistent protection across digital and physical copies.
