Soalan Lazim
- What encryption standard is used?
- AES-256 encryption per the PDF 2.0 specification — the strongest available PDF encryption standard.
- What is the difference between user and owner passwords?
- The user password is required to open the PDF. The owner password controls permissions (printing, copying, editing) — it can be set separately from the user password.
- Can I restrict printing or copying?
- Yes — use the permission checkboxes to control: Print, Copy Text, Edit Content, Fill Forms, Add Annotations, and Assemble Document.
- Is the password stored anywhere?
- No. Your password is used only in-browser to encrypt the PDF and is never transmitted or stored.
