Owner Password

This PDF is readable but has an owner password that restricts modifications. Enter the owner password to add or change protection settings.


Set passwords

Set a user password to require opening credentials, or leave it blank and use only an owner password for permissions-only protection.

Encryption algorithm

AES-256 — industry-standard encryption used for all protected PDFs.

Permissions

Permissions depend on viewer support and are best-effort restrictions. Some PDF viewers may still allow text selection, copying, or other actions.

Privacy

Clears document information and XMP metadata when applying or removing protection.
