The Permission password is the master password for the document. It can be used by the file owner to set permissions, or to open
the file if an Open password is set.
Some PDF compatibility options, such as PDF/X-3 and PDF/A-1b, do not let you set PDF file permissions. If you choose such a
compatibility option, all controls on the Security page appear disabled. To change the compatibility, see “To select a compatibility
option” on page 662.

Optimizing PDF files
You can optimize PDF files for different versions of Adobe Acrobat or Acrobat Reader by choosing a compatibility option that matches the
type of viewer used by the recipients of the PDF file. In CorelDRAW, you can select one of the following compatibility options: Acrobat 4.0,
Acrobat 5.0, Acrobat 6.0, Acrobat 8.0, Acrobat 9.0, PDF/X-1a, PDF/X-3, or PDF/A-1b.The available controls differ, depending on which
compatibility option you choose. If you are publishing a PDF file for a wide distribution, it is better to choose an earlier compatibility option
such as Acrobat 8.0 or 9.0 to ensure that the file can be viewed in earlier versions of Acrobat. However, if security is a concern, you may
want to choose a later version because the encryption levels are higher. For more information, see “Setting security options for PDF files” on
page 661.
You can optimize the viewing of a PDF document on the web to speed up the loading time of the PDF.
If you added complex fills to the document, you can choose to convert them to bitmaps, which is also known as rasterizing. This may
increase the PDF file size, but it will ensure that the complex fills display correctly.
