## FAQ

### Can you unlock a PDF if I forgot the password?

No. This tool only decrypts with the password you supply. There is no brute-force or recovery feature.

### Is my password uploaded?

No. Unlocking runs in your browser. The password stays in the tab.

### Is unlocking a PDF I own legal?

Generally yes when you own the file or have permission and know the password. Do not unlock documents you are not allowed to open.
