常见问题
Can this break a password I do not know?
No. This tool needs the correct password. It does not guess or crack passwords.
Is my password sent anywhere?
No. Unlocking runs in your browser and the password stays on your device.
What are printing or editing limits?
Some PDFs open freely but forbid printing or copying. These limits are removed in the unlocked copy. Only remove limits from files you are allowed to change.
