Generalization in map making is about simplifying features so a map remains readable when shown at smaller scales. The main aim is to reduce data volume and computational load while preserving the essential geometry and spatial relationships of the features. When you zoom out, tiny details become unnecessary or clutter the map, so they are removed or simplified. Techniques include removing small features, merging adjacent areas, simplifying lines, smoothing curves, and preserving important shapes and topology. By keeping the overall form and relationships while using less data and fewer vertices, the map still communicates the geography clearly without overwhelming the viewer.

This is why reducing data volume while preserving the essential geometry is the best choice. Increasing detail would hurt readability at small scales; randomizing vertices would distort geometry; converting to raster is not the goal of generalization.
