Is the watermark permanent?
The watermark is embedded in the PDF. While it's visible, someone with PDF editing software could potentially remove it. For security-critical documents, consider using password protection as well.

Currently, our tool supports text-based watermarks. Image watermarks may be added in a future update.
Will the watermark appear on all pages?
Yes, the watermark is applied to every page of the document for consistent protection.
