PDF Document comparison
This lets you compare two PDF files with similar content - typically an
earlier and later version of one document. Access this from the
Document menu, then choose to see a visual or a textual comparison,
with a side-by-side or combined presentation. The latter shows only one
document and marks object or text changes: new text is underlined
while deleted text appears in a marker tooltip.
PDF to Word Document comparison
PDF Professional is able to compare a PDF file with a particular version
of a Word file; typically this will be the file the PDF was made from. It
can show which changes were made since the PDF was created. The
comparison is made within Word, the result can be displayed in a
temporary file that you can save if required.
PDF splitting
You can split large PDF files into a set of smaller ones so they are easier to
distribute. Access this from the Document menu and choose splitting
criteria: by file size, blank pages, number of pages, bookmarks, document
structure, etc. You can also extract pages by criteria that you specify.
PDF portfolios
Portfolios let you collect a set of documents relating to a particular topic
for convenient distribution. PDF Professional provides this by extending
the previous PDF Create support for packages. A portfolio is superior to
a package because it can contain documents of differing file types (all
documents in a package must be PDF files) as well as folders and folder
structures. Support for displaying non-PDF pages is added.
Package PDF files
PDF Create lets you select a set of files and have their copies grouped in a
single PDF package file. Any non-PDF files you select enter the package
as PDF files. To include non-PDF files in a package in their original
format, open a package, open a PDF inside it, and attach these files. You
can add a cover page to the package. Help explains how different PDF
programs let you use and unpack received packages.
