Encrypting a PDF File

When converting a scanned document to a PDF file, you can encrypt the file. You can set an encryption level, a document open password, a permission password, and use permissions for the created PDF file. The higher the encryption level is, the higher the security level is.

A document open password is intended to open an encrypted PDF file. A document open password cannot be the same as a permission password. You can enter up to 32 characters.

A permission password is intended to control printing, extracting, editing, or other operations for encrypted PDF files. A permission password cannot be the same as a document open password. You can enter up to 32 characters.

Note

  • [Encrypted PDF] is displayed only if [File Format] is set to [PDF].

  • To encrypt a PDF file, you must set a document open password or permission password.

Memo

  • The permission setting items for printing and editing a PDF file vary depending on the encryption level.

  • A permission to print a document, a permission to extract text and graphic, and a permission to change a document are displayed only if you select [Enable] or [Apply Default Password] for [Permissions Password].
