Frequently Asked Questions
1. What is the difference between a User Password and an Owner Password?
A User Password (or Document Open Password) is required just to open and view the PDF. An Owner Password (or Permissions Password) is required to bypass restrictions like printing, copying text, or editing the document.
2. Is this secure? Are my files uploaded anywhere?
Yes, it is extremely secure. This tool uses AES-256 encryption, the highest standard for PDF security. Moreover, all encryption happens entirely locally in your web browser. Your files are NEVER uploaded to any external server.
3. What happens if I forget my password?
Because the encryption is standard and strong (AES-256), there is no 'backdoor' to recover your document if you forget the password. Please make sure to save your passwords securely before closing the tab.
