Select Document Properties in the Document menu. The Document Properties dialog box has five panels: Description, Security, Initial View, Custom and Fonts.
Description
Under Description you find the Standard fields, such as Title, Author, Subject, Keywords. These values can be modified. Other values, such as Creator, Created and Modified cannot be changed.
Under Advanced you find PDF Producer, PDF Version, File Size, Page Size, Location and Number of Pages.
Security
For details see Security Properties.
Initial View
The Initial View options define how the document will be displayed when it is opened. These options are stored in the document and will be followed by any capable PDF viewer program.
Custom
You can include custom defined application-specific key-value document property pairs to the PDF document.
Later, other document management applications can retrieve the information for post-processing.
For example, you can make a custom field searchable by defining it in the custom field list before building the index.
Note
If any property is modified, you will be prompted to save the document before closing it.
Fonts
Use this to show all the fonts referenced in the document. This helps you to understand whether font substitution is used to show unavailable fonts; or if fonts are embedded in the document.
