Load once
A short wait, then no waiting.
Plug in the card. Keeper reads every photo once and keeps a sharp preview on your Mac, so each arrow press is instant. Open the card again and it's ready at once.
Keyboard first
Every key does one thing.
Arrows to move. Shift to select a run. R to rotate, losslessly. Delete sends the shot and its RAW to the Trash, and ⌘Z brings it back.
On-device smarts
It spots the misses for you.
Keeper checks every shot for blur and bad exposure, on your Mac. Press F to see only the flagged ones, select them all, and delete in one go.
Share the keepers
Straight into Photos.
Select the good ones and press P to add them to your library, or ⇧P for a new album ready to share as a Shared Album. Or send them with AirDrop or Messages.
