## Description

Forgot the password on an important PDF? Need to secure a document before sharing? PDF Lock: Unlock & Protect makes it simple — unlock or password-protect any PDF right on your iPhone or iPad, in just a few taps.

Your files never leave your device. Everything is processed locally using Apple's built-in PDF engine. No uploads. No cloud. No account required. No ads. Just fast, private PDF security whenever you need it.

UNLOCK PDFs IN SECONDS
Remove password protection from any PDF and get back to reading, editing, or sharing. Enter the current password, and your unlocked file is ready to export — to Files, Mail, WhatsApp, or any app you use.

LOCK PDFs WITH A PASSWORD
Keep sensitive documents safe before you send them. Add strong password protection to any PDF so only the right people can open it. (PDF Lock is included with PDF Lock: Unlock & Protect Pro.)

BUILT-IN PDF VIEWER
Preview your unlocked or locked PDF inside the app before you export. Scroll through every page with a clean, full-screen viewer — no extra apps needed.

EASY EXPORT & SHARE
Save processed PDFs to the Files app or share them instantly with the native iOS share sheet. Your workflow stays simple and familiar.

PDF HISTORY
Revisit your recently processed files without hunting through folders. Open past PDFs directly from your history list and pick up where you left off.
