Frequently Asked Questions
Quick direct-answer guides about using this utility tool locally and securely.
Can I decrypt a PDF without knowing the password?
No, client-side decryption requires the correct password (user or owner password) to unlock the cryptographic container of the PDF.
Is it safe to unlock confidential PDFs using this tool?
Yes, the decryption process runs 100% locally in your browser memory. Your confidential files and passwords never touch our servers.
Does unlocking remove all permissions restrictions?
Yes, once unlocked with the correct password, a new unencrypted PDF is generated without any passwords or viewing/printing restrictions.
What is the difference between a Document Open password and a Permissions/Owner password?
A Document Open password (also called a "user password") prevents anyone from viewing the PDF until entered, while a Permissions password (or "owner password") lets you open and read the file but restricts actions like printing, copying, or editing — KuberAgent can remove both, provided you have the correct password.
Is it legal to remove the password from a PDF?
Yes, as long as the PDF belongs to you or you have permission from the owner to modify it — removing a password from a file you don't have rights to access may violate copyright or privacy policies, so only unlock documents you're authorized to use.
Will unlocking a PDF change its formatting or reduce quality?
No, removing the password protection only affects the file security settings — your content, formatting, layout, images, and text remain exactly the same.
Can I unlock multiple PDF files at once?
Currently, files are processed one at a time to ensure accurate local decryption — for multiple files, upload and unlock each PDF individually.
What is the difference between password protection and encryption in a PDF?
Password protection restricts who can open or use a PDF, while encryption is the underlying technology that scrambles the file content so it can't be read without the correct decryption key — most password-protected PDFs are also encrypted, since the password typically serves as the decryption key.
