Frequently Asked Questions

1 Can this tool unlock any PDF without knowing the password?
No. To decrypt locked files, you must provide the correct user opening password or owner permissions password. The tool does not brute-force or crack passwords.
2 What restrictions can this tool remove from a PDF?
The tool removes open password prompts, print limitations, text selection blocks, page extraction limits, and annotation locks.
3 Will the unlocked PDF retain its original digital signatures?
Removing passwords or security properties alters the file hash. Any official third-party cryptographic digital signatures will be invalidated to prevent tampering.
4 Can I decrypt multiple password-protected files at once?
Yes. You can upload multiple locked documents, providing their respective passwords in the list staging area to process them sequentially.
5 Are my passwords or decryption outputs stored or tracked?
Never. All authentication checks, decryption logic, and PDF saving occur inside your browser sandbox runtime. Passwords are never sent over the web.
