Wonderfulshare PDF Password Locker & Remover — Complete Guide and ReviewThis guide explains what Wonderfulshare PDF Password Locker & Remover does, how it works, its main features, installation and setup, step‑by‑step usage for common tasks, performance and reliability, security and privacy considerations, pricing and licensing, a brief comparison with alternatives, and final verdict and recommendations.
What it is
Wonderfulshare PDF Password Locker & Remover is a desktop application designed to help users secure PDF files by adding passwords and permissions, and to remove or recover passwords from PDFs when access is lost or restrictions need changing. It targets individuals and small businesses who routinely encrypt PDFs for confidentiality or occasionally need to unlock files for legitimate use.
Key features
- Password protection: add owner and user passwords to PDFs to restrict opening, editing, printing, copying, and form filling.
- Password removal: remove user/owner passwords from PDFs when you have the right to do so.
- Password recovery: attempt to recover lost user/owner passwords via brute‑force, dictionary, and smart mask attacks.
- Batch processing: encrypt, decrypt, or recover multiple PDFs in a single run.
- User interface: graphical UI with a wizard for common tasks and options for advanced users.
- Format preservation: attempts to retain original layout, metadata, and embedded fonts when processing files.
- Preview and metadata: view file metadata before and after operations.
Supported platforms: Typically Windows (check vendor site for macOS/Linux availability).
Supported PDF versions: Most common PDF versions up to a reasonably recent spec (specific limits depend on the app version).
Installation and setup
- Download the installer from the official Wonderfulshare site or an authorized distributor.
- Run the installer and follow the on‑screen prompts. Choose an installation folder and optional shortcuts.
- Launch the app. On first run, you may be prompted to register or enter a license key (free trial may be available).
- Configure basic preferences: default output folder, overwrite behavior, and whether to preserve metadata.
Tip: Keep the installer and license information in a safe place; uninstallers and trial limits vary by vendor.
How it works — basic concepts
- User password vs. owner password: a user password is required to open the PDF. An owner (or permissions) password restricts certain actions (printing, editing) while allowing opening. Wonderfulshare can add either or remove them if conditions are met.
- Encryption strength: PDFs can be encrypted with different algorithms and key lengths (e.g., AES‑128, AES‑256, RC4). Stronger encryption increases security but also the time needed for brute‑force recovery.
- Recovery methods:
- Brute‑force attack: tries all possible combinations; time scales exponentially with password length and character set.
- Dictionary attack: uses wordlists of likely passwords.
- Mask/smart attack: uses known patterns (lengths, known characters) to reduce search time.
Step‑by‑step guide: Add password protection
- Open Wonderfulshare PDF Password Locker & Remover.
- Choose “Add Password” or “Encrypt PDF” from the main menu.
- Click “Add files” or drag‑and‑drop the PDFs you want to protect.
- Choose protection type:
- User password (open file)
- Owner password (restrict actions)
- Enter the password(s) and select encryption algorithm if options are provided (e.g., AES‑256).
- Configure permissions (allow printing, copying, editing, form filling).
- Set output folder and file naming (overwrite or create copy).
- Click “Start” or “Apply.” Wait for confirmation.
Result: Protected PDF(s) saved to your chosen folder.
Step‑by‑step guide: Remove or recover a password
Removing a password (when you already know it):
- Open the app and select “Remove Password” or “Decrypt PDF.”
- Add the encrypted PDF.
- Enter the known password when prompted.
- Choose output settings and click “Start.” The app will produce an unencrypted copy.
Recovering a lost password:
- Select “Recover Password” or “Crack PDF Password.”
- Add the target PDF.
- Choose recovery method:
- Dictionary (select a wordlist)
- Brute‑force (choose character sets: lowercase, uppercase, digits, symbols)
- Mask attack (specify known pattern)
- Configure performance options (number of CPU threads, GPU acceleration if available).
- Start the attack and monitor progress. Time to success depends on password complexity and system resources.
Note: Recovery is only lawful for files you own or have explicit permission to access.
Performance and reliability
- Encryption/decryption for files you can open is typically fast and reliable; batch processing speeds depend mainly on I/O and CPU.
- Recovery speed depends heavily on hardware. Modern multi‑core CPUs and GPU acceleration (if supported) significantly improve brute‑force performance.
- Success rate for recovery depends on password strength: simple dictionary passwords are often recoverable; long complex passwords with full character sets can be infeasible to crack within reasonable time.
Security and privacy considerations
- Use strong, unique passwords when protecting PDFs (12+ characters, mix of types).
- If using the recovery feature, ensure you have legitimate rights to access the file. Unauthorized removal of protection can be illegal.
- Check how the application handles files: prefer local processing (no cloud upload) for sensitive documents. Confirm vendor documentation about telemetry and data handling.
- Keep backups of original files before batch operations to prevent accidental data loss.
Pricing and licensing
Wonderfulshare applications commonly use a freemium model: a free trial with limitations (watermarks, file size limits, or restricted features) and paid licenses for full functionality. Licensing options may include single‑user, multi‑user, or lifetime licenses plus paid upgrades. Confirm current pricing on the vendor’s website.

Legal and ethical note
Password removal or cracking should only be used on PDFs you own or have explicit permission to modify. Accessing or decrypting files without authorization may violate laws or terms of service.
Pros and cons
| Pros | Cons |
|---|---|
| User‑friendly GUI and batch operations | Paid software — full features behind a license |
| Multiple recovery methods and format preservation | Recovery not guaranteed for strong passwords |
| Options for both protection and removal | Platform availability may be limited (often Windows) |
| Useful for businesses and power users | Legal risks if used improperly |
Final verdict and recommendations
Wonderfulshare PDF Password Locker & Remover is a practical tool for users who need a simple GUI to both protect PDFs and attempt recovery when passwords are lost. It’s best suited for those who prefer a guided interface and batch tools rather than command‑line utilities. For sensitive documents, verify the app’s local processing and privacy stance; for robust enterprise needs, consider commercial PDF suites with integrated document management.
