The benefit
The speed comes from keeping the action close to Finder and the Dock. Drag, drop, let DropMachine reduce, then continue with the smaller file in place.
Benefit
DropMachine saves time by removing the round trip through a full editor, upload site, export settings panel, and duplicate-file cleanup.

The speed comes from keeping the action close to Finder and the Dock. Drag, drop, let DropMachine reduce, then continue with the smaller file in place.

Quick fix
DropMachine makes size reduction feel like a small action.
