How to use Protect PDF
- This tool is not functional. Password-protected PDF writing is not implemented.
- Do not plan workflows around this tool. It cannot encrypt or password-protect PDFs.
- For password protection, use LibreOffice (free), Adobe Acrobat, or qpdf (CLI).
- For privacy without passwords, use Deep Metadata Scrubber + Flatten instead.
- This page exists for transparency. We list it as coming-soon rather than hiding it.
Tips
- Scrub + Flatten provides stronger privacy than a weak PDF password. PDF passwords are trivially crackable with free tools.
- If you need to restrict who can open a document, use encrypted email or a secure file-sharing platform instead of PDF passwords.
- PDF user passwords (restrict printing/copying) provide zero security. They are cosmetic only.
Privacy: Hybrid processing — cloud opt-in required for some operations.
