Add a confidentiality stamp, header/footer banners, and restriction metadata to your PDF.
How this works: Browser-based apps cannot apply cryptographic PDF passwords — that requires server-side processing. Instead, this tool adds a visible confidentiality watermark (diagonal stamp + header/footer banners) and sets restriction metadata on your document. For true password encryption, use Adobe Acrobat or a desktop PDF tool.
