Frequently Asked Questions (Q&A)
What is the difference between an Open Password and an Owner Password?
An Open Password (User Password) is required just to open and view the PDF content. An Owner Password (Permissions Password) is used to lock specific features, like printing, copying text, or editing the document, even if the user is allowed to read it.
Is it safe to encrypt my private documents here?
Absolutely. Because the process is 100% browser-based, your files are never uploaded to the internet. We do not store, view, or transfer your data. Security is guaranteed by the architecture of the tool itself.
Do I need to install software?
No. This tool works directly in your web browser (Chrome, Edge, Firefox, Safari). It provides desktop-class performance and advanced permission settings without the need for bulky software installations.
What happens if I forget the password?
Please store your passwords in a safe place. Since we do not upload your data or save your passwords to any servers, it is impossible for us to recover a forgotten password for you once the file is encrypted.
