Frequently Asked Questions

What encryption level is used?

AES-256 encryption is used, the same standard used by banks and governments.

Does this preserve bookmarks and form fields?

No. The protected copy is built from the pages alone, so annotations are kept but bookmarks are dropped and form fields are no longer fillable.

What PDF versions are supported?

Encryption works on PDF 1.0 through 2.0. The output uses AES-256, the standard current PDF readers open.
