PDF Secure - Password Protect

PDF Secure lets you add, remove and change PDF passwords in seconds — privately, right on your iPhone and iPad. Your documents are processed on your device and never uploaded.

PROTECT ANY PDF
- Add a password so only people you trust can open your document
- See password strength as you type, and confirm it so you never mistype it
- Control what readers can do: block printing or copying with a separate permissions password
- Uses standard PDF password protection that works in all major PDF readers

UNLOCK OR CHANGE PASSWORDS — THE RIGHT WAY
- Remove a password when you know it, then save an unlocked copy or replace the original
- Change a password in one simple step
- PDF Secure never bypasses, cracks or recovers passwords — you always need the document's current password

KEEP EVERY PDF IN ONE PLACE
- Import PDFs from Files, Mail, Safari or any app with "Open in"
- Every file you import or create is saved in your library, ready when you need it
- Add favorites, search, and sort by name, date or size
