PDF Professional respects security settings applied to PDF files. PDF files
can be protected by passwords and security settings. Two of these settings
are examined by PDF Professional : Printing permitted or prohibited, and Copying
Content permitted or prohibited.
Open password
This grants access to a file in accordance with its security settings.
Permissions password
This grants full access to a file regardless of its security settings.
PDF Professional behavior
If you try to open a protected PDF file, a dialog
box will invite you to supply the necessary password. Enter this carefully
because only one attempt is permitted.
The following table summarizes the program behavior when a protected
PDF file should be converted and only the open password is given.
This information is equally true for 40-bit, 128-bit and 256-bit encryption.

Note1
Handling of image-only pages depends on the state of the
Image-only pages selection box under Processing options in the Standard,
Legal, Spreadsheet and Form panels. The selection box provides the following
choices: Convert Page with OCR / Skip / Add to Document as Image.
Note2
If the program uses the PDF content information, a faster
and more accurate result can be achieved (as compared to OCR).
