PDF WOLF lets you add password protection to any PDF, directly on your device. No cloud uploads. No accounts. No servers involved. Your files stay private from start to finish. HOW IT WORKS Import any PDF from Files, iCloud Drive, or any app on your device. Choose to generate a cryptographically strong random password automatically, or enter your own. PDF WOLF applies industry-standard PDF encryption on-device, then verifies the result before presenting it to you. Once protection is complete, you can preview the result. Saving the protected PDF to Files or sharing it directly requires a Pro plan. WHAT YOU GET — Import any PDF from Files or iCloud Drive — Generate a strong random password with one tap — Enter and confirm your own password manually — On-device encryption — your PDF never leaves your iPhone or iPad — Verification step confirms encryption worked before you save — Password vault: all passwords stored securely in your device's Keychain — Reveal, copy, or reference any saved password from the Passwords tab — Protection history with thumbnail previews of past protected files — Save protected PDFs directly to Files (Pro) — Share protected PDFs via AirDrop, Mail, Messages and more (Pro) PRIVACY FIRST PDF WOLF uses no analytics, no tracking, and no advertising SDKs. It communicates only with Apple's App Store to process purchases. Everything else happens entirely on your device. PRO PLAN A Pro plan (Weekly or Lifetime) unlocks the ability to save protected PDFs to the Files app and share them via the iOS share sheet. The protection process itself can be experienced before purchasing — Pro gates only the final file delivery. Passwords are stored in your device's Keychain, the same secure storage used by banks and password managers. PDF WOLF never sees or stores your passwords on any server.
