Visualize and Compare PDFs
The Visualizer allows you to explore aspects of a page that may be relevant for printing purposes, such as color applications, color spaces, safety zone or page object types. You will find this option in the “Reports” category and in the “View” menu of the standalone edition.
Whereas, the 'Compare' feature simply compares 2 PDFs and creates a report.
Visualizer on CLI
--visualizer [--usebleed] [--safetyoutside=safetyoutside] [--safetyinside=safetyinside] [--gamut_method=gamut_method] [--gamut_targetprofile=gamut_targetprofile] [--gamut_currentprofile=gamut_currentprofile] [--gamut=gamut] [--smlobj=smlobj] [--inkcov=inkcov] [--bmpres=bmpres] [--imgres=imgres] [--part=part] [--resolution=resolution] [--sep_colors] [--jpegformat=jpegformat] [--compression=compression] [--imgformat=imgformat] [-p=p] [-l=l]Purpose
Create a report listing print relevant aspects of a PDF document. Some usage examples can be found in this article.

Example:

--part=ink --imgformat=png --pagerange=1-5 <PDF file>Please note that 'pdfreport' as format is only functional until and including pdfToolbox 11.
Compare PDF
The Compare feature in pdfToolbox 12 Desktop comes with a resolution setting to compare the parameters and the possibility to easily navigate to the previous or next page with differences.
Also "Delta C" and "Delta E" variants have been added as new channels with pdfToolbox 12.
Below is a comparison of 2 files at 72 ppi:
Below is a comparison of 2 files at 36 ppi (where the pixels can be seen due to the low rendering resolution.):
