How Automatic Password Recovery Works

When you upload a password-protected PDF, our tool:

1. First attempts to remove owner-password restrictions (no password needed)
2. Tries common passwords like "123456", "password", "admin", etc.
3. Runs through an extensive wordlist of 850,000+ known passwords
4. If successful, shows you the discovered password and provides the unlocked PDF
5. If not found, prompts you to enter the password manually

When Would You Need to Unlock a PDF?

• Forgotten password: You protected a PDF and forgot the password
• Inherited documents: Received protected PDFs without the password
• Sharing convenience: Share documents without sending passwords separately
• Archiving: Store documents without password dependencies
• Combining documents: Merge protected PDFs into one document
• Printing needs: Remove print restrictions from PDFs

Understanding PDF Password Types

User Password (Open Password)

Required to open and view the PDF. Our tool can attempt to recover this automatically using common password patterns.

Owner Password (Permissions Password)

Controls what you can do with the PDF. This can usually be removed without knowing the password.

Frequently Asked Questions

Can you really recover PDF passwords automatically?

Yes! Our tool uses a database of 850,000+ common passwords. If your PDF uses a common or weak password, there is a good chance we can find it automatically.

How long does automatic recovery take?

Usually just a few seconds for common passwords. For the full wordlist scan, it may take up to 60 seconds.

Is my PDF secure during processing?

Yes, all files are processed securely on our servers and deleted immediately after processing.

What if automatic recovery does not work?

If we cannot find the password automatically, you will be prompted to enter it manually. Very strong or unique passwords may not be in our database.

Is this legal?

Only use this tool on PDFs you own or have permission to unlock. Unlocking documents without authorization may violate laws in your jurisdiction.
