Frequently Asked Questions
How does the PDF protection remain private?
We implement the PDF-lib encryption standard directly within your browser. When you set a password, your computer re-encodes the document structure with the user and owner passwords locally. Your unencrypted data never exits your system's physical RAM.
What is the difference between User and Owner passwords?
Currently, our tool sets both the User and Owner passwords to the same value for maximum protection. The User password is required to open and view the document, while the Owner password restricts permissions like printing or metadata modification.
Can I recover my password if I lose it?
No. Because your encryption keys are unique to your document and never stored on our servers, there is no way for us to recover or reset a lost password. Please ensure you keep a secure record of your chosen key.
