I generate tech reports, with HUGE files sizes of micro-photographs. Our company e-mail attachment sizes are default limited by its Exchange Server, but NO LONGER! Neuxpower is very easy to use; I just drag and drop; reduce (I use "Tighter" settings quite often with no loss in detail) from large jpeg to small jpeg; then sometimes convert to pdf (alternate software); then (again, sometimes) this large pdf to small pdf (using Neuxpower in "Tighter" mode). Yeah, this may sound like a lot of steps but note really - it's good and fast. This has saved my deadlines countless times.
