their original values.
New
Click the New button to create a new conversion control.
Delete
The Delete button removes the currently selected conversion control.
Default
This returns supplied controls to default values and removes user-defined

Security
You can add passwords to PDF files you create and prohibit or allow actions,
such as printing, extracting content and editing. Choose a standard control and
click Advanced to specify passwords and permissions.
You can specify two passwords:
Open Password
Anyone providing this password can view the PDF it protects. This is sometimes
called a user password. Further use of such a PDF depends on which
permissions are set.
Permission Password
Anyone providing this password can view the PDF and use it freely, regardless of
permission settings. They can also modify, remove or add permission settings.
This is sometimes called a master or owner password.
Before setting permissions you must supply and confirm a permission password
and specify the encryption strength: 40-bit or 128-bit. This determines which
permissions are available. Make your settings and click OK.
Use New to name a new standard security control, make the desired settings
and click OK. Use Delete to remove a security control. Use Default to return
supplied controls to default values and remove user-defined controls.
