If you've forgotten the password to your PDF, don't panic. The good news is that your document data is usually
not lost. Instead of trying random passwords or uploading confidential files to online services, it's better to use a dedicated offline password recovery solution.
I recently used
SysTools PDF Password Recovery Tool, and it worked well for recovering the forgotten
user/open password without modifying the original PDF. The software uses
Brute Force and
Mask Attack recovery modes, making it suitable for both completely unknown and partially remembered passwords. It supports recovery of passwords up to
15 characters, allows custom character sets (letters, numbers, symbols, etc.), shows real-time recovery progress, and performs the entire process offline, so your confidential documents never leave your computer. Most importantly, it recovers the password without affecting the PDF's formatting or content. Download the software on Windows or macOS.
Once the password is recovered, you can open the PDF and use
SysTools PDF Password Remover to permanently remove the password from the document. The tool supports both
user and owner passwords (when the correct password is known), removes restrictions on printing, copying, editing, commenting, and form filling, and processes multiple PDFs in batch mode. It also preserves the original formatting, supports AES-128- and AES-256-bit encrypted PDFs, works completely offline, requires no Adobe Acrobat installation, and is compatible with both Windows and macOS.
So, my recommendation is:
- Recover the forgotten password using SysTools PDF Password Recovery.
- Enter the recovered password into SysTools PDF Unlocker.
- Save a new password-free copy of the PDF for hassle-free future access.
This two-step approach is much safer and more reliable than using online tools, especially when you're dealing with important documents like bank statements, legal files, research papers, or business reports.
