Protect PDF: Password Lock

Lock, Unlock & Change PDFs

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Protect PDF is a simple PDF security app for locking, unlocking and changing PDF passwords directly on your iPhone. Import a PDF from Files, choose the action you need and export the processed document when you are done. Your files are handled locally on your device, with no account and no upload flow. What you can do: • Protect a PDF with an opening password • Unlock a protected PDF when you know the current password • Change an existing PDF password • Generate a strong password and copy it to the clipboard • Allow or block printing and text copying when protecting a file • Save, share or export the processed PDF • Review your recent processed files in the local history Built for private documents: Protect PDF is designed for invoices, forms, contracts, study notes, work documents and any PDF you want to share more safely. The workflow is intentionally focused: import, choose protect, unlock or change password, then save or share. All PDF tools are available in the app. An optional one-time purchase removes ads. Protect PDF does not replace legal or enterprise document management systems. Always keep your password somewhere safe, because a protected PDF cannot be opened without the correct password.
