Frequently asked questions
Which encryption is used?
AES-256 with revision 6 handlers, supported by every current PDF reader.
Can you recover my password later?
No. The password is never stored on our side. If you lose it, the document cannot be opened.
Can I stop people copying text?
Yes. Text extraction and editing are blocked by default, and you can also decide whether printing is allowed.
