Protect documents

Set a password, unlock when you have permission, and flatten PDFs. Keep the original, remember the password, and check the document after processing.

Flatten PDF

Fix form fields, visible signatures and supported annotations into the page content to limit editing each object individually.

Encrypt a PDF with a password to restrict people without the password from opening and reading the document's content.

Remove the password requirement from a PDF when you know the current password and have the right to change the document's protection.
