Frequently Asked Questions

How does Auto-Unlock work if I don't know the password?

Are my sensitive documents uploaded to any server?

No! Calculatorz runs completely client-side inside your web browser. Neither your file nor any password is ever uploaded to any server or cloud database.

Can I unlock bank statements and Aadhaar card PDFs?

Yes! Simply select the 'Bank / Salary Statement' or 'Aadhaar Pattern' option in the Auto-Unlock tab, and the tool will assist in unlocking and permanently removing the password.

Will the unlocked PDF open in Adobe Acrobat and Google Chrome?

Yes, the resulting PDF is standard ISO-compliant and opens without passwords in all PDF readers, including Adobe Acrobat, Apple Preview, Chrome, Edge, and mobile viewers.
