I recently needed to access a PDF document whose password I had completely forgotten. Since the file contained important information, I did not want to upload it to an online password recovery website. I was looking for an offline solution that could recover both unknown and partially remembered PDF passwords.
I tried the SysTools PDF Password Recovery Tool, which is designed to recover forgotten PDF user passwords using Brute Force and Mask Attack techniques. The software works offline on Windows and macOS, so the PDF remains on the local system during the recovery process.
Key Features I Found Useful
Steps I Followed to Recover the PDF Password
My Experience
For a completely forgotten password, I found the Brute Force option more appropriate, while Mask Attack can significantly narrow the search when you remember even a small part of the password. The main advantage for me was that the recovery process was performed offline, which is preferable when dealing with confidential documents such as financial reports, business records, or personal PDFs.

Key Features I Found Useful

- Mask Attack: Helpful when you remember some details about the password, such as its beginning, character types, or length.
- Custom Charset: You can select letters, numbers, symbols, spaces, and other character types to narrow the recovery process.
- Password Length Settings: The tool supports password recovery up to 15 characters, according to the product documentation.
- Unknown & Partially Known Password Recovery: It can work with both completely forgotten and partially remembered passwords.
- Offline Processing: The PDF is processed locally instead of being uploaded to an online server.
- Original File Integrity: The software is designed to recover the password without changing the PDF's formatting, layout, or metadata.
- Windows & macOS Support: Available for both Windows and Mac systems.
- Progress Monitoring: The interface provides recovery progress information while the process is running.
Steps I Followed to Recover the PDF Password
- Download and launch the SysTools PDF Password Recovery Tool on Windows or macOS.
- Click Browse and select the password-protected PDF file.

- Click Recover to begin the password recovery process.
- Once the password is recovered, use it to open the protected PDF.
