About this app

PDF Lock & Unlock is a simple PDF security tool that helps you protect PDF documents with a password or unlock password-protected PDF files using the correct password.

Protect important documents, secure sensitive PDF files, and remove password protection when you have the authorized password. The app provides two focused PDF security tools in one place: Lock PDF and Unlock PDF.

SIMPLE PDF PROTECTION

Choose Lock PDF or Unlock PDF from the home screen.

To protect a document, select your PDF, enter and confirm a password, and create a protected PDF.

To unlock a protected document, select the PDF and enter its existing password. If the password is correct, the app creates a new unlocked PDF.

YOUR ORIGINAL PDF STAYS UNCHANGED

PDF Lock & Unlock creates a separate output file instead of replacing your original PDF. Your original document remains available on your device.

For example, a protected document can be saved as a new locked PDF, while an unlocked document can be created as a separate copy.

SECURE PDF DOCUMENTS

PDF Lock & Unlock is designed for everyday document security and password protection. Use it for PDFs containing personal documents, business files, reports, forms, records, and other documents that need password protection.

IMPORTANT

PDF Unlock requires the correct password for a protected PDF. The app does not bypass, guess, or crack PDF passwords.

WHY USE PDF LOCK & UNLOCK?

• Lock PDF documents with password protection
• Unlock PDFs when you know the password
• Protect sensitive PDF files
• Remove PDF password protection when authorized
• Keep original PDF files unchanged
• Use a focused PDF security tool without unnecessary PDF editing features

PDF Lock & Unlock brings PDF password protection and PDF password removal together in one simple application.

Whether you need to lock a PDF, protect a PDF with a password, unlock a password-protected PDF, or remove PDF password protection using the correct password, PDF Lock & Unlock provides the essential tools in one place.
