In ArcGIS Pro, exports in vector format are much larger than the same map exported from ArcMap.
While Acrobat Pro’s option to reduce file size helps to some extent, users may not have access to this software. ‘Generalizing’ features in ArcGIS Pro reduces the size of files, but forces the user to modify their original data set.
It would be great to add a setting to generalize features as part of the export process, leaving the original data unaltered. So many maps become part of larger presentations, and the cumulative effect of large map sizes is significant.
