About Reduce Image Size by Resizing

You can reduce image size by resizing — fewer pixels often means a smaller file and faster load times. This page uses VSPic resize tooling (not compression-only) for users who want dimensional reduction first.

After resizing, open Compress Image if you still need a lower KB count at the same dimensions.
